[0020] In this embodiment, the civil engineering structure 5 will be described mainly in the case where it is a civil engineering structure supporting a railway track as described above, but the civil engineering structure 5 handled by the structure design support system 1 (each of the devices 2 to 4 described below) is not limited to the above example and may be any civil engineering structure related to a railway. In addition to the above examples, examples of the civil engineering structure 5 related to a railway include station buildings, platforms, slopes, underpasses, etc. Furthermore, the type of member 51 is not limited to the above example and may be specified according to, for example, the structural type, structural form, construction method, etc. of the civil engineering structure 5.

[0021] The main components of the structure design support system 1 include a structure design support device 2 used by a designer who designs the civil engineering structure 5 (5A to 5E), a worker terminal device 3 used by a worker or manager who performs research, planning, design, ordering, construction, maintenance, etc. related to the civil engineering structure 5, and a database device 4 that stores various data related to the civil engineering structure 5. Each of the devices 2 to 4 is, for example, configured as a general-purpose or dedicated computer, and is connected to a wired or wireless network 10 so as to be able to transmit and receive various data to and from each other. Note that the number of the devices 2 to 4 and the configuration of the network 10 are not limited to the example in FIG. 1.

[0022] The structure design support device 2 is composed of, for example, a desktop computer or a portable computer. Programs such as applications and browsers are installed in the structure design support device 2, and the structure design support device 2 accepts various input operations and outputs various information via a display screen or voice. The structure design support device 2 also transmits and receives various data to and from a database device 4, and supports work related to the design of the civil engineering structure 5 by, for example, displaying various data related to the civil engineering structure 5 on a display screen, accepting input operations on the display screen, registering new data in the database device 4, or correcting registered data.

[0023] The worker terminal device 3 is composed of, for example, a stationary computer or a portable computer. Programs such as applications and browsers are installed in the worker terminal device 3, and the worker terminal device 3 accepts various input operations and outputs various information via a display screen or voice. For example, the worker terminal device 3 transmits and receives various data to and from the database device 4, displays the contents of various data related to the civil engineering structure 5 on the display screen, accepts various input operations on the display screen, registers new data in the database device 4, and modifies registered data, thereby supporting work related to the survey, planning, ordering, construction, maintenance, and management of the civil engineering structure 5.

[0024] The database device 4 is configured, for example, by a server-type computer or a cloud-type computer. The database device 4 includes a database 40 that manages structure management data 41 related to the design of a civil engineering structure 5 for each construction site 6. As shown in Fig. 1, the database device 4 may be shared throughout the entire life cycle, or a dedicated database device 4 may be prepared for each stage of the life cycle.

[0025] Fig. 7 is a data configuration diagram showing an example of structure management data 41 managed in database 40. The structure management data 41 includes wiring data, topographical data, design conditions, structure models 50, two-dimensional drawings, quantity summary tables, etc. The database 40 shown in Fig. 7 illustrates a case in which structure management data 41 for structures A, B, ..., N is registered.

[0026] 8 is a schematic diagram showing an example of wiring data. The wiring data is data in which a track center line 100 indicating the center line of a track installed at the construction site 6 is recorded as three-dimensional data. The wiring data may be created in the investigation and planning stage, for example, by a program other than the structure design support program 210 described later, or may be created as a part of the function of the structure design support program 210.

[0027] Fig. 9 is a schematic diagram showing an example of topographical data. The topographical data is data in which the ground surface 60 and the supporting layer 61 at the construction site 6 are recorded as three-dimensional data. The topographical data of the ground surface 60 is created based on the measurement results, for example, by measuring the height of the ground surface 60 from the sky using a measuring device capable of measuring the height as a point cloud, during the investigation and planning stage. The topographical data of the supporting layer 61 is created based on the investigation results, for example, by conducting a boring investigation at multiple points during the investigation and planning stage.

[0028] The topographical data may include information (position, size, material, etc.) about the buried object 62 buried in the ground. The buried object 62 includes, but is not limited to, for example, a water pipe, a gas pipe, a subway, an underground road, an underground building, etc. In this case, the buried object 62 may be partially installed above ground. The topographical data may also include information about the strength of the support layer 61.

[0029] The design conditions include design conditions for the civil engineering structure 5 and design conditions for the members 51 .

[0030] As the design conditions of the civil engineering structure 5, structure design values ​​are set for each of a plurality of structure design items that define the three-dimensional shape of the civil engineering structure 5. As the design conditions of the members 51, member design values ​​are set for each of a plurality of member design items that define the three-dimensional shape of the members 51 for each type of member 51. Note that in this embodiment, the design conditions of the civil engineering structure 5 and the members 51 are described below mainly with reference to conditions related to the three-dimensional shape, but may also include, for example, characteristic values ​​of the load when a train is running, characteristic values ​​related to the environment such as temperature, materials of concrete, metal, and composite members, materials and cover of reinforcing bars, etc.

[0031] The structure model 50 is composed of multiple component models 510 of multiple types, and is data representing the three-dimensional shape of the civil engineering structure 5. The multiple component models 510 of multiple types are data created corresponding to the structural types of the civil engineering structure 5 and the structural forms of the civil engineering structure 5 determined for each structural type of the civil engineering structure 5, and each component model 510 is data representing the three-dimensional shape of a component 51.

[0032] The structure model 50 and the component model 510 are data whose three-dimensional shapes can be displayed at any viewpoint, magnification, transparency, and display color, and are configured as data that can be converted into any outline drawing, cross-sectional drawing, etc. The structure model 50 and the component model 510 are data created by the structure design support device 2, and any data format can be adopted. As the data format of the structure model 50 and the component model 510, for example, a data format called a BIM (Building Information Modeling) model can be adopted.

[0033] Since the component model 510 differs for each type of component 51, the multiple component design items that define the three-dimensional shape differ for each type of component 51. The component model 510 defines the three-dimensional shape of the component 51 by setting component design values ​​for fixed and variable target component design items as the multiple component design items.

[0034] Fixed component design items are component design items for which component design values ​​are manually set by the designer. Variable component design items are component design items for which component design values ​​are automatically set by the structure design support device 2. In each component model 510, which component design items are fixed or variable can be appropriately determined by the designer or the structure design support device 2, and may differ for each type of component 51. In this case, all component design items may be fixed component design items or variable component design items.

[0035] In the plurality of component models 510 constituting the structure model 50, component setting values ​​for a plurality of component design items are set for each of the component models 510, whereby the structure model 50 is created.

[0036] Hereinafter, the design conditions and structure models 50 (50A to 50E) of the viaduct, bridge, tunnel, and underground structure 5E will be described with reference to Figs.

[0041] In FIG. 10, columns 52E, 52F and piles 52G are illustrated as types of components 51, but component setting values ​​for a plurality of component design items are set for other types of components 51 in the same manner.

[0043] Fig. 11 shows a case where the three-dimensional shapes of the column models 520E and 520F are defined by further setting a component design value for "column height", which is a variable component design item, in the column models 520E and 520F. Also, Fig. 11 shows a case where the three-dimensional shape of the pile model 520G is defined by further setting a component design value for "pile length", which is a variable component design item, in the pile model 520G.

[0064] When the type of component 51 is upper deck 55A, the component design items are, for example, component thickness, material, etc. Fig. 16 illustrates a case where component design values ​​for "component thickness" and "material" are set as component design items of the fixed object.

[0065] When the type of member 51 is pile 55D, the member design items are, for example, cross-sectional shape, cross-sectional dimensions, pile length, embedment, etc. Fig. 18 illustrates a case where member design values ​​for "cross-sectional shape", "cross-sectional dimensions", and "embedding" are respectively set as the member design items of the fixing target.

[0066] In FIG. 18, the upper deck 55A and the piles 55D are illustrated as types of components 51, but component setting values ​​for a plurality of component design items are set for other types of components 51 in the same manner.

[0067] Corresponding to each component 51 (upper deck 55A, side wall 55B, lower deck 55C, pile 55D) of the underground structure 5E, an upper deck model 550A, a side wall model 550B, a lower deck model 550C, and a pile model 550D are defined, as shown in Figure 19.

[0068] Fig. 19 illustrates a case where the three-dimensional shape of upper deck model 550A is defined by further setting component design values ​​for "component thickness" and "material," which are variable component design items, in upper deck 55A. Fig. 19 also illustrates a case where the three-dimensional shape of pile model 550D is defined by further setting component design values ​​for "pile length," which is a variable component design item, in pile model 550D.

[0069] The two-dimensional drawing is data representing an outline drawing or a cross-sectional drawing of the civil engineering structure 5 or the member 51. The two-dimensional drawing is created by the structure design support device 2 based on the structure model 50 and the member model 510.

[0070] The quantity summary table is data that summarizes the quantity of the member 51 by type. The quantity summary table is created by the structure design support device 2 based on the structure model 50 and the member model 510.

[0071] Each data constituting the structure management data 41 may be referenced by the structure design support device 2 and the worker terminal device 3 and displayed on a display screen of the structure design support device 2 and the worker terminal device 3, or may be transmitted and received between the structure design support device 2 and the worker terminal device 3. In this case, each data of the structure management data 41 may be edited or printed according to the permission authority given to the designer or worker. Furthermore, each data of the structure management data 41 may be subject to version management, for example, so that the structure model 50 and component model 510 before and after editing may be included in the structure management data 41.

[0072] In addition, the data configuration of the structure management data 41 is not limited to the above example and may be changed as appropriate, some of the above data may be omitted, and data other than the above may be added. For example, various work records performed in ordering, construction, maintenance, etc. may be associated with the structure management data 41.

[0073] (Configuration of structural design support device 2) 20 is a block diagram showing an example of a structure design support device 2. The structure design support device 2 includes a control unit 20 configured with a processor such as a CPU, an MPU, etc., a storage unit 21 configured with an HDD, an SSD, a memory, etc., a communication unit 22 which is a communication interface with the network 10, an input unit 23 configured with a keyboard, a mouse, etc., and an output unit 24 configured with a display, etc.

[0074] The storage unit 21 stores the structure design support program 210, as well as an operating system, a browser, other programs, various data, etc. The structure management data 41 may be stored in the storage unit 21 instead of the database 40 of the database device 4.

[0075] The control unit 20 functions as a data receiving unit 200, a design condition receiving unit 201, a model creation unit 202, a 2D drawing creation unit 203, and a quantity summary table creation unit 204 by executing a structure design support program 210 stored in the memory unit 21.

[0076] Each of the parts 200 to 204 of the control unit 20 causes the output unit 24 to display various display screens, and receives various input operations on the display screens via the input unit 23 to operate.

[0077] (Structure design support method) The following describes a series of operations (structure design support method) performed by the structure design support device 2. The series of operations is performed by each unit of the structure design support device 2 (each step of the structure design support method executed by the structure design support program 210).

[0078] 21 is a flowchart showing an example of the operation of the structure design support device 2. The following describes the operation when a designer issues an instruction to execute a structure design support program 210 via the input unit 23 of the structure design support device 2, and the control unit 20 of the structure design support device 2 supports the design of a civil engineering structure 5 (in this embodiment, a rigid frame viaduct 5A with a two-line three-column, back-split type column and pile foundation) that is the design target.

[0079] In step S10 (data receiving process), the data receiving unit 200 receives wiring data (see FIG. 8 ) in which a track centerline 100 at a construction site 6 where a civil engineering structure 5 to be designed is to be constructed is recorded as three-dimensional data, and topographical data (see FIG. 9 ) in which a ground surface 60 and a supporting layer 61 at the construction site 6 are recorded as three-dimensional data. For example, when a designer specifies a reference destination for the wiring data and the topographical data on a display screen on which a file name or the like can be specified, the data receiving unit 200 receives the reference wiring data and the topographical data, and registers the referenced wiring data and the topographical data in the database 40.

[0080] In step S11 (design condition receiving step), the design condition receiving unit 201 receives design conditions related to the civil engineering structure 5 and the members 51.

[0081] Specifically, in step S110, the design condition receiving unit 201 receives structure design values ​​for a plurality of structure design items that define the three-dimensional shape of the civil engineering structure 5 as design conditions of the structure model 50. For example, the design condition receiving unit 201 displays a structure setting screen 11 for setting design conditions of the structure model 50, receives the design conditions of the structure model 50 on the display screen, and registers them in the database 40.

[0082] Fig. 22 is a diagram showing an example of a structure setting screen 11 for setting design conditions for a structure model 50. The structure setting screen 11 has design value input boxes 110, 111 for inputting structure design values ​​for structure design items. Fig. 23 shows the design value input box 110 in which designation of a structure type and a structure format can be input as structure design items. As a result, the design condition receiving unit 201 receives the designation of a structure type and a structure format as structure design items.

[0083] In this embodiment, a case will be described in which a "viaduct" is specified as the structural type and a "two-line three-column, split-back columns, rigid-frame viaduct with pile foundations" is specified as the structural style in the design value input box 110.

[0084] Next, in step S111, the design condition receiving unit 201 receives, as design conditions for the component model 510, component design values ​​for component design items to be fixed, among the component design values ​​for multiple component design items that define the three-dimensional shape of the component 51 for each type, for each component model 510.

[0085] In this embodiment, the design condition receiving unit 201 receives member design values ​​for member design items to be fixed for each member model 510 corresponding to the structural type and structural format specified as the structure design items. That is, the design conditions are received for each of the slab model 520A, the vertical beam model 520B, the cross beam model 520C, the balustrade model 520D, the column models 520E and 520F, the pile model 520G, and the root-wrapped steel pipe model 520H as the multiple member models 510 constituting the rigid-frame viaduct 5A with a two-line three-column, back-split type column and pile foundation.

[0086] At this time, the design condition receiving unit 201 displays the component setting screen 12 for setting the design conditions of the component model 510, receives the design conditions of the component model 510 on the display screen, and registers them in the database 40.

[0087] Fig. 23 is a diagram showing an example of a member setting screen 12 for setting design conditions for a member model 510. The member setting screen 12 includes a member selection tab 120 for selecting the type of member 51, and a design value input box 121 for inputting member design values ​​for member design items. Fig. 23 shows a case where the design value input boxes 121 for column models 520E and 520F are displayed.

[0088] In the design value input box 121, component design items for which component design values ​​have been input by the designer (in the example of FIG. 23, "cross-sectional shape," "cross-sectional dimensions," and "soil cover") are treated as component design items that are fixed in the subsequent processing. On the other hand, component design items for which component design values ​​have not been input by the designer (in the example of FIG. 23, "column height") are treated as component design items that are variable. In this embodiment, a case will be described in which "column height," a component design item of column models 520E and 520F, and "pile length," a component design item of pile model 520G, are treated as component design items that are variable.

[0089] In step S12 (model creation process), the model creation unit 202 creates a structure model 50 based on the design conditions accepted in step S11 by placing multiple types of component models 510 on the ground surface 60 and supporting layer 61 recorded in the topographical data, based on the track center line 100 recorded in the wiring data, and registers the structure model 50 in the database 40.

[0090] Specifically, in step S120, the model creation unit 202 determines the number of component models 510 to be arranged for each type, based on structure design values ​​for a plurality of structure design items.

[0091] For example, depending on the structural design values ​​for the structural type "two-line, three-column type, split-back columns, rigid-frame viaduct with pile foundation", the structural design value for the bridge length "45m", the structural design value for the number of spans "3", etc., the number of component models 510 (specifically, slab model 520A, vertical beam model 520B, horizontal beam model 520C, parapet model 52D, columns 52E, 52F, piles 52G, wrapped steel pipe 52H) corresponding to each component 51 (specifically, slab 52A, vertical beam model 520B, horizontal beam model 520C, parapet model 520D, column models 520E, 520F, pile model 520G, wrapped steel pipe model 520H) to be arranged is determined.

[0092] Next, in step S121, the model creation unit 202 arranges the multiple component models 510 three-dimensionally along the track center line 100 based on the positional relationship between the component model 510, the track center line 100, the ground surface 60, and the support layer 61, and determines the component design value for the component design item to be changed for each component model 510. At that time, when the design condition reception unit 201 receives the "soil cover" of the column models 520E and 520F and the "embedding" of the pile model 520G as the component design item to be fixed in a specific type of component model 510 among the multiple types of component models 510, the model creation unit 202 determines the component design value for the component design item to be changed (in this embodiment, the "column height" of the column models 520E and 520F, and the "pile length" of the pile model 520G) for each column model 520E, 520F or for each pile model 520G so as to satisfy the embedding or the soil cover.

[0093] For example, a slab model 520A is placed based on the track centerline 100, and vertical beams 52B and horizontal beams 52C are placed to support the lower surface of the slab model 520A, while balustrade models 520D are placed at both ends in the width direction of the upper surface of the slab model 520A. Then, column models 520E and 520F are placed to support the lower surface of the slab model 520A and to be connected to the respective ends of the vertical beam model 520B and horizontal beam model 520C.

[0094] At that time, the "column height" which is a variable target member design item in the column models 520E, 520F is determined based on the lower surface of the slab model 520A supported by the column models 520E, 520F, the height of the ground surface 60 on which the column models 520E, 520F are installed, and the member setting value for the "earth cover" which is a fixed target member design item in the column models 520E, 520F. At that time, it may be determined whether or not a middle-layer beam (not shown) is necessary depending on whether or not the length of the determined "column height" is longer than a predetermined specified value. If it is determined that a middle-layer beam is necessary, a middle-layer beam model (not shown) is arranged so as to be connected to the column models 520E, 520F.

[0095] Furthermore, the pile model 520G and the root-wrapped steel pipe model 520H are arranged so that the lower ends of the column models 520E, 520F and the upper end of the pile model 520G are surrounded by the root-wrapped steel pipe model 520H.

[0096] At this time, the pile length, which is a variable target member design item in the pile model 520G, is determined based on the upper surface of the pile model 520G arranged in a position surrounded by the root-wrapped steel pipe model 520H, the height of the support layer 61 on which the pile model 520G is installed, and the member setting value for the "embedding" which is a fixed target member design item in the pile model 520G. At this time, it may be determined whether or not an underground beam (not shown) is necessary depending on whether or not the determined "pile length" is longer than a predetermined specified value. If it is determined that an underground beam is necessary, an underground beam model (not shown) is arranged so as to be connected to the pile model 520G.

[0097] Subsequently, in step S122, the model creation unit 202 creates the structure model 50 by setting component design values ​​for the component design items of the fixed object and the variable object for each component model 510. That is, the model creation unit 202 sets the component design values ​​for the component design items of the fixed object received in step S111 and the component design values ​​for the component design items of the variable object determined in step S121 in the component models 510, respectively, thereby defining the three-dimensional shapes of the component models 510. Then, by defining the three-dimensional shapes of each component model 510, the three-dimensional shape of the structure model 50 composed of each component model 510 is defined.

[0098] 24 is a diagram showing an example of the structure model display screen 13 displaying the structure model 50. The structure model display screen 13 includes a model display area 130 displaying the structure model 50, a 2D drawing creation button 131 for instructing the creation of a 2D drawing based on the structure model 50, and a quantity summary table creation button 132 for instructing the creation of a quantity summary table based on the structure model 50. The model display area 130 is configured to be able to update the display form of the structure model 50 in response to operation input such as enlargement, reduction, rotation, etc. The model display area 130 may be configured to be able to select a component model 510 (a plurality of component models 510 may be able to be selected at once), and may be configured to be able to edit component design values ​​for component design items in the selected component model 510 (a plurality of component models 510 may be able to be edited at once).

[0099] In this embodiment, it is assumed that the 2D drawing creation button 131 is pressed, the process proceeds to step S13, and the quantity summary table creation button 132 is further pressed, the process proceeds to step S14.

[0100] In step S13 (two-dimensional drawing creation step), the two-dimensional drawing creation unit 203 creates a two-dimensional drawing representing an outline drawing or a cross-sectional view of the civil engineering structure 5 or member 51 based on the structure model 50. At that time, the two-dimensional drawing creation unit 203 may extract a cross-section including the main dimensions (column dimensions, pile dimensions, etc.) of the civil engineering structure 5 or member 51, and create a two-dimensional drawing representing the extracted cross-section. In addition, the two-dimensional drawing creation unit 203 may create a two-dimensional drawing representing a cross-section in a normal direction to the track center line 100 of a straight or curved portion, or may create a two-dimensional drawing representing a cross-section in a direction along the track center line 100.

[0101] 25 is a diagram showing an example of a two-dimensional drawing display screen 14 that displays a two-dimensional drawing. The two-dimensional drawing display screen 14 includes a two-dimensional drawing display area 140 that displays a two-dimensional drawing, a type selection box 141 that indicates the type of outline drawing or cross-sectional drawing, and a two-dimensional drawing save button 142 that instructs saving the two-dimensional drawing. The two-dimensional drawing may include not only line drawings of the civil engineering structure 5 and members 51, but also dimension lines, materials, construction methods, and the like.

[0102] In step S14 (quantity summary table creation process), the quantity summary table creation unit 204 creates a quantity summary table that records the counted results by adding up the quantities of the components 51 for each type based on the component design values ​​for a plurality of component design items.

[0103] 26 is a diagram showing an example of a quantity summary table display screen 15 that displays a quantity summary table. The quantity summary table display screen 15 includes a quantity summary table display area 150 that displays the quantity summary table, a type selection box 151 that specifies the type of the quantity summary table, and a quantity summary table save button 152 that specifies saving of the quantity summary table. The quantity summary table, for example, tallies the quantities of columns and piles based on member design values ​​such as column height and pile length, and displays the tallied quantities in a table format.

[0104] As described above, according to the structure design support device 2 and the structure design support method according to the present embodiment, the work of a designer when creating a three-dimensional model of a civil engineering structure 5 can be simplified.

[0105] (Other embodiments) The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention. All such modifications are included in the technical concept of the present invention.

[0106] In the above embodiment, the functions of the units 200 to 204 of the structure design support device 2 are described as being realized by one device, but the functions of the units may be distributed among a plurality of devices to be realized by a plurality of devices. Also, the control unit of the worker terminal device 3 may function as the structure design support device 2 by executing the structure design support program 210.

[0107] In the above embodiment, the structure design support device 2 operates according to the flowchart shown in FIG. 21. However, the order of execution of each step (process) may be changed as appropriate, and some steps (processes) may be omitted.

[0108] In the above embodiment, the case has been described in which the design condition receiving unit 201 receives design conditions related to a rigid-frame viaduct 5A as the structure type and structure format, and the model creating unit 202 creates the structure model 50A of the rigid-frame viaduct 5A. In contrast, the design condition receiving unit 201 may receive design conditions related to an arbitrary civil engineering structure 5, and the model creating unit 202 may create the structure model 50 of the arbitrary civil engineering structure 5. Below, a description will be given of cases (first to fourth creation examples) in which the model creating unit 202 creates the structure models 50B to 50E of a simple girder bridge 5B, a mountain tunnel 5C, a shield tunnel 5D, and an underground structure 5E, respectively, in step S12 (model creating step).

[0109] As a first creation example, the model creation unit 202 creates a structure model 50B (see FIG. 13) of a simple girder bridge 5B based on the design conditions of the simple girder bridge 5B as shown in FIG. 12. Specifically, the number of component models 510 (specifically, the main girder model 530A, the abutment body model 530B, the abutment foundation model 530C, the pier body model 530D, and the pier foundation model 530E) corresponding to each component 51 (the main girder 53A, the abutment body model 53B, the abutment foundation model 530C, the pier body model 530D, and the pier foundation model 530E) is determined according to the structure design values ​​for the structure design items such as the bridge length and the number of spans. Then, based on the positional relationship between the component models 510, the track centerline 100, the ground surface 60, and the support layer 61, each component model 510 is three-dimensionally arranged along the track centerline 100. In addition, the component design values ​​for the variable component design items (in the example of Figure 12, the "abutment height" of the abutment body model 530B and the "pier height" of the pier body model 530D) are determined for each component model 510 so as to satisfy the component design values ​​for the fixed component design items (e.g., embedment or soil cover) in a specific type of component model 510.

[0110] As a second creation example, the model creation unit 202 creates a structure model 50C (see FIG. 15) of the mountain tunnel 5C based on the design conditions of the mountain tunnel 5C as shown in FIG. 14. Specifically, the number of component models 510 (specifically, the arch model 540A, the side wall model 540B, the invert model 540C, the deformed steel bar model 540D, and the torsion steel bar model) corresponding to each component 51 (arch 54A, side wall 54B, invert 54C, deformed steel bar, and torsion steel bar) is determined according to the structure design values ​​for the structure design items such as the starting point and the structure type. At that time, the number of the deformed steel bar model 540D and the torsion steel bar model is determined by selecting the cross-sectional shape of the mountain tunnel 5C (for example, one of the support patterns A, B, and C) according to the positional relationship between the track center line 100 and the support layer 61 and the ground strength of the support layer 61. Then, when the design condition receiving unit 201 receives at least one of the soil cover from the ground surface 60 and the distance from the buried object 62 as a structure design item, each component model 510 is three-dimensionally arranged along the track center line 100 so as to satisfy the structure design value for at least one of the structure design items of the soil cover and the distance, based on the positional relationship between the component model 510 and the track center line 100, the ground surface 60, the supporting layer 61, and the buried object 62. In addition, the component design value for the variable component design item is determined for each component model 510.

[0111] As a third creation example, the model creation unit 202 creates a structure model 50D (see FIG. 17) of the shield tunnel 5D based on the design conditions of the shield tunnel 5D as shown in FIG. 16. Specifically, the number of component models 510 (specifically, the A-segment model 540F, the B-segment model 540G, and the K-segment model 540H) corresponding to each component 51 (the A-segment 54F, the B-segment model 540G, and the K-segment model 54H) is determined according to the structure design values ​​for the structure design items such as the starting point and the structure type. Then, when the design condition receiving unit 201 receives at least one of the earth covering from the ground surface 60 and the distance from the buried object 62 as the structure design items, the component models 510 are three-dimensionally arranged along the track center line 100 so as to satisfy the structure design values ​​for at least one of the structure design items of the earth covering and the distance, based on the positional relationship between the component models 510, the track center line 100, the ground surface 60, the support layer 61, and the buried object 62. In addition, by selecting the cross-sectional shape (component thickness, material (RC, steel, composite)) of the shield tunnel 5D depending on the ground strength of the supporting layer 61 and the acting load (soil overburden weight, earth pressure, overburden load, etc.), the component design values ​​for the variable component design items (in the example of Figure 16, ``component thickness'' and ``material'' in the A segment model 540F, B segment model 540G, and K segment model 540H) are determined for each component model 510.

[0112] As a fourth creation example, the model creation unit 202 creates a structure model 50E (see Fig. 19) of an underground structure 5E based on the design conditions of the underground structure 5E as shown in Fig. 18. Specifically, the number of component models 510 (specifically, upper deck model 550A, side wall model 550B, lower deck model 550C, pile model 550D) corresponding to each component 51 (upper deck 55A, side wall 55B, lower deck model 550C, pile 55D) is determined according to the structure design values ​​for the structure design items such as the starting point and structural form. When the design condition receiving unit 201 receives at least one of the soil cover from the ground surface 60 and the distance from the buried object 62 as a structure design item, each component model 510 is arranged with reference to the track center line 100 so as to satisfy the structure design value for at least one of the structure design items of the soil cover and the distance, based on the positional relationship between the component model 510 and the track center line 100, the ground surface 60, the support layer 61, and the buried object 62. At that time, the longitudinal gradient of the track center line 100 may be adjusted according to the soil cover from the ground surface 60 and the distance from the buried object 62. Also, by selecting the cross-sectional shape (component thickness, material (RC, steel, composite)) of the underground structure 5E according to the ground strength and applied load (soil covering weight, earth pressure, surcharge load, etc.) of the support layer 61, the component design values ​​for the component design items to be changed (in the example of FIG. 18, the "material" and "component thickness" of the upper deck model 550A) are determined for each component model 510. Furthermore, by considering uplift, subsidence, etc. according to the position of the support layer 61, the pile model 550D is positioned, and the component design values ​​for the component design items to be changed (in the example of FIG. 18, the "pile length" of the pile model 550D) are determined for each component model 510.

[0113] In the above embodiment, the design condition receiving unit 201 receives designation of structure design values ​​for a structure type and a structure format as structure design items. In contrast, designation of at least one of the structure type and the structure format may be omitted. For example, when both the structure type and the structure format are omitted, the structure design support device 2 may function as a device that creates a structure model 50 corresponding to a specific structure type and structure format by the model creation unit 202.

[0114] In the above embodiment, the design condition receiving unit 201 receives the designation of "pile foundation" as the structure design value for the structural type of the foundation, and the model creating unit 202 places the pile model 520G. In contrast, the designation of the structural type of the foundation may be omitted. In this case, the model creating unit 202 may select, for example, one of the pile foundation, spread foundation, and caisson foundation based on the positional relationship between the ground surface 60 and the support layer 61, and place one of the pile model 520G, the footing model, and the caisson foundation model. In this case, if the topographical data includes information on the strength of the support layer 61, the strength of the support layer 61 may be further taken into consideration.

[0115] In the above embodiment, the model creation unit 202 has been described as registering and storing the structure model 50 created based on the design conditions in the database 40, but the storage location of the structure model 50 is not limited to the above example.
