Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel design, in particular to an auxiliary tunnel center mileage determination method based on group optimization. BACKGROUND

[0002] In the process of railway mountain tunnel construction, construction period and engineering cost affect the selection of tunnel scheme. For a super-long tunnel, if only one-way or opposite construction of the tunnel is considered, the construction period generally cannot meet the overall project demand, so an auxiliary tunnel needs to be set in the middle of the tunnel to shorten the construction period. Because tunnel excavation is carried out in different grades of rock, the excavation construction speed is not the same, which affects the overall construction period of the auxiliary tunnel, and the number of auxiliary tunnels also affects the engineering cost, so determining the number and layout position of auxiliary tunnels is an important factor to be considered in the process of optimizing construction period and cost.

[0003] At present, the design of auxiliary tunnels by designers often relies on inherent design experience. Whether the design experience is rich or poor determines whether the auxiliary tunnel scheme is accurate. Whether there is an optimization space for the auxiliary tunnel scheme cannot be known from objective data calculation, which does not meet the requirement of refined design. Moreover, in actual scheme design, the tunnel line scheme is often adjusted and changed, and the geological information is also updated continuously in the process of drilling. The conventional auxiliary tunnel design idea cannot be quickly updated, and the auxiliary tunnel scheme cannot be adjusted accordingly. The adjustment of upstream data requires designers to re-study and draw the auxiliary tunnel scheme, which is low in efficiency and cannot be updated accordingly, and cannot meet the requirement of rapid drawing.

[0004] Therefore, how to effectively improve the design efficiency of the auxiliary tunnel scheme is a problem to be solved at present.

[0062] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0063] In order to better understand the technical solutions of the present application, the specific embodiments will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] The main solution of the embodiment of the present application is: acquiring tunnel engineering data, and determining the number of construction work areas according to the tunnel engineering data; determining a tunnel reference construction period under the auxiliary tunnel based on the number of construction work areas; determining an initial center mileage of the auxiliary tunnel based on the tunnel reference construction period; acquiring a tunnel actual construction period under the auxiliary tunnel, and optimizing the initial center mileage based on the tunnel actual construction period to obtain a target center mileage of the auxiliary tunnel.

[0065] At present, the design of the auxiliary tunnel by the designer often relies on inherent design experience, and whether the auxiliary tunnel scheme is accurate depends on the richness and scarcity of the design experience. Whether there is an optimization space for the auxiliary tunnel scheme cannot be known from objective data calculation, which does not meet the requirement of refined design. Moreover, in actual scheme design, the tunnel line scheme is often adjusted and changed, and the geological information is also updated constantly in the drilling process. The conventional auxiliary tunnel design idea cannot be quickly updated, and the auxiliary tunnel scheme cannot be adjusted specifically. The adjustment of the upstream data causes the designer to re-study and draw the auxiliary tunnel scheme, the auxiliary tunnel scheme design efficiency is low, the auxiliary tunnel scheme cannot be updated specifically, and cannot adapt to the requirement of rapid drawing. Therefore, how to effectively improve the auxiliary tunnel scheme design efficiency is a problem to be solved at present.

[0066] The present application determines the reference construction period by determining the number of construction work areas, thereby determining the initial center mileage and optimizing it to obtain the target center mileage. The initial center mileage is quickly determined by the number of construction work areas and is constantly optimized, which can quickly and accurately locate the auxiliary tunnel center mileage, overcomes the technical defect of low auxiliary tunnel scheme design efficiency, and can effectively improve the auxiliary tunnel scheme design efficiency.

[0067] It should be noted that the execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, or an electronic device capable of realizing the above functions, an auxiliary tunnel center mileage determination device based on group optimization, etc. The following will take the auxiliary tunnel center mileage determination device based on group optimization as an example to describe the embodiment and the following embodiments.

[0068] Based on this, the embodiment of the application provides an auxiliary tunnel center mileage determination method based on group optimization, which refers to Figure 1 , Figure 1 The flowchart of the first embodiment of the auxiliary tunnel center mileage determination method based on group optimization of the application is shown in the figure.

[0069] In the embodiment, the auxiliary tunnel center mileage determination method based on group optimization comprises steps S10-S40:

[0070] Step S10, acquiring tunnel engineering data and determining the number of construction work areas according to the tunnel engineering data.

[0071] It should be noted that the tunnel engineering data refers to various data generated in the design and construction process of the tunnel project, including the overall duration of the tunnel, the length of the tunnel, the construction speed and length of each stratum within the tunnel range, and the construction duration of a single auxiliary tunnel, etc., which are not specifically limited in the embodiment.

[0072] It can be understood that the tunnel engineering data can be obtained in various ways, such as from design drawings, construction records, geological survey reports, etc., and the tunnel engineering data is crucial for determining the number of construction work areas, because the division of construction work areas will directly affect the efficiency and quality of tunnel construction. When determining the number of construction work areas, factors such as the overall duration of the tunnel, the length of the tunnel, and the stratum construction speed should be considered comprehensively to ensure that the division of construction work areas is reasonable and efficient.

[0073] Step S20, determining the tunnel reference construction duration under the auxiliary tunnel based on the number of construction work areas.

[0074] It should be noted that the tunnel reference construction duration refers to the theoretical duration required for tunnel construction obtained by the first recalculation duration under the condition of setting an auxiliary tunnel. When determining the tunnel reference construction duration, factors such as the number of construction work areas, the length of the tunnel, and the stratum construction speed can be considered comprehensively.

[0075] It can be understood that when the construction duration of tunnel unidirectional construction and bidirectional construction both do not meet the demand of the overall duration, an auxiliary tunnel needs to be set in the middle of the tunnel to shorten the construction duration, and the construction time of each construction work area after setting the auxiliary tunnel is the construction duration of a single construction work area minus the construction duration of a single auxiliary tunnel.

[0076] In one feasible implementation, step S20 may include: determining the number of auxiliary tunnels based on the number of construction work areas; determining the construction time of each construction work area based on the number of auxiliary tunnels; and determining the reference construction period of the tunnel under the auxiliary tunnels based on the construction time of each construction work area.

[0077] It should be noted that the number of auxiliary tunnels is determined based on the number of construction work areas. That is, if the number of construction work areas is even, the number of auxiliary tunnels N = number of construction work areas / 2 - 1; if the number of construction work areas is odd, the number of auxiliary tunnels N = (number of construction work areas + 1) / 2 - 1.

[0078] like Figure 2 As shown, Figure 2 The diagram illustrates a construction zone with an odd number of sections. The tunnel length is divided into three sections based on the construction zones, meaning there are three construction zones. The connection point between two construction zones is the boundary between adjacent construction zones. When there are three construction zones, there are two connection points between them.

[0079] like Figure 3 As shown, Figure 3 The diagram shows a construction zone with an even number of sections. The tunnel length is divided into 4 sections based on the construction zones, meaning there are 4 construction zones. The connection point between construction zones is the boundary between adjacent construction zones. When there are 4 construction zones, there are 3 connection points between construction zones.

[0080] It is understandable that the construction time of each construction section can be obtained based on the number of auxiliary tunnels and the sum of the construction time of all strata within the tunnel area. This is the tunnel construction period under the auxiliary tunnels with a quantity of N, i.e., the reference construction period of the tunnel under the auxiliary tunnels.

[0081] Step S30: Determine the initial center mileage of the auxiliary tunnel based on the reference construction period of the tunnel.

[0082] It should be noted that the initial center mileage is determined based on a comprehensive analysis of the tunnel's reference construction period and tunnel engineering data. After determining the initial center mileage, the center mileage of the auxiliary tunnels needs to be optimized based on the actual conditions of the tunnel engineering data to ensure it meets the actual construction requirements. The optimization process may include multiple iterations and adjustments until the optimal target center mileage is obtained.

[0083] Understandably, the center mileage of an auxiliary tunnel refers to its position during tunnel construction, specifically the location of the intersection of the auxiliary tunnel's centerline and the tunnel axis along the tunnel's length. Determining the center mileage of the auxiliary tunnel is crucial for the smooth progress of tunnel construction, directly impacting construction efficiency and project costs.

[0084] It is worth noting that the initial center mileage of the auxiliary tunnel is determined based on the tunnel's reference construction period and the distribution of the construction area. When determining the initial center mileage, the connection point of the construction area and the impact of the auxiliary tunnel on the construction area need to be considered.

[0085] In one feasible implementation, step S30 may include: determining the boundary mileage of each construction zone according to the tunnel reference construction period; obtaining the index number at the boundary mileage and performing parity judgment based on the index number; when the index number is odd, using the boundary mileage as the initial center mileage of the auxiliary tunnel.

[0086] It should be noted that the boundary mileage of each construction section is calculated based on the tunnel's reference construction period, tunnel stratum velocity, and distance, and this boundary mileage is added to the set. The parity of the index number at the boundary mileage is used to determine whether the mileage is the initial mileage of the construction section or the initial mileage of the auxiliary tunnel. If the number is even, it is the initial mileage of the construction section; if the number is odd, it is the initial center mileage of the auxiliary tunnel.

[0087] like Figure 4 As shown, Figure 4 To illustrate the auxiliary tunnel and construction area diagram, the tunnel length is divided into multiple construction areas based on the overall tunnel construction period, the construction speed Vi of each stratum within the tunnel, and the length li. The first and last construction areas are located at the tunnel entrance. The boundary between adjacent construction areas is the connection point of the construction area. The boundary between adjacent construction areas can also be the location of the auxiliary tunnel. The auxiliary tunnel is the starting point of the construction area, and the connection point is the ending point of the construction area.

[0088] Step S40: Obtain the actual construction period of the tunnel under the auxiliary tunnel, and optimize the initial center mileage based on the actual construction period of the tunnel to obtain the target center mileage of the auxiliary tunnel.

[0089] It should be noted that the actual construction period of the tunnel under the auxiliary tunnel, i.e. the required construction period, must conform to the overall progress of the tunnel project.

[0090] It is understandable that, due to changes in the tunnel's route and geological information, there may be some discrepancies between the reference construction period and the actual construction period. To ensure that the design of the auxiliary tunnel meets the actual construction requirements, it is necessary to obtain the actual construction period of the tunnel under the auxiliary tunnel and optimize the initial center mileage based on this actual construction period. This will allow for data adjustment and updates, adapting to the requirements of rapid drawing production for the auxiliary tunnel design, thereby improving engineering design efficiency.

[0091] In a feasible implementation, step S40 can include: comparing the actual tunnel construction period with the reference tunnel construction period; updating the number of auxiliary tunnels until the reference tunnel construction period corresponding to the updated number of auxiliary tunnels is less than or equal to the actual tunnel construction period, to obtain a target number of auxiliary tunnels; determining a target tunnel construction period according to the target number of auxiliary tunnels; and determining a target center mileage of the auxiliary tunnel according to the target tunnel construction period.

[0092] It should be noted that the target tunnel construction period is a theoretical period required for tunnel construction obtained by recalculating the period under the target number of auxiliary tunnels. By comparing the actual tunnel construction period with the reference tunnel construction period, the deviation between the two can be found in time, so that appropriate measures can be taken for adjustment. When the reference tunnel construction period is greater than the actual tunnel construction period, it indicates that the current number of auxiliary tunnels can be too small, and the number of auxiliary tunnels needs to be increased to shorten the period. In the process of increasing the number of auxiliary tunnels, the number of auxiliary tunnels needs to be updated constantly, and the reference tunnel construction period needs to be recalculated until the reference tunnel construction period is less than or equal to the actual tunnel construction period.

[0093] In a specific implementation, if the reference tunnel construction period is greater than the actual tunnel construction period, one auxiliary tunnel is added, the reference tunnel construction period is recalculated according to the updated number of auxiliary tunnels until the reference tunnel construction period is less than the actual tunnel construction period, and if the reference tunnel construction period is less than the actual tunnel construction period, a new initial center mileage of the auxiliary tunnel is calculated according to the current number of auxiliary tunnels, and the new initial center mileage of the auxiliary tunnel is taken as the target center mileage.

[0094] It should be noted that the basic principle of the auxiliary tunnel center mileage determination method based on optimization in the embodiment is as follows: before the auxiliary tunnel is arranged, the overall tunnel construction period, the tunnel length, the construction speed and length of each stratum within the tunnel range, and the construction period of a single auxiliary tunnel are determined; the tunnel is processed by slicing according to the period by using the greedy algorithm, and the number of construction work areas is preliminarily obtained; the number of auxiliary tunnels is determined according to the number of construction work areas and the parity characteristics thereof; the overall tunnel construction period is recalculated according to the determined number of construction work areas; the length of the construction work area is calculated according to the new tunnel construction period; the preliminary center mileage of the auxiliary tunnel is determined according to the length of the construction work area and the period boundary position thereof; the construction period of the auxiliary tunnel is determined, the tunnel construction period is recalculated until it is less than the required period, and the steps of “recalculating the overall tunnel construction period according to the determined number of construction work areas” to “determining the preliminary center mileage of the auxiliary tunnel according to the length of the construction work area and the period boundary position thereof” are repeated to calculate the final center mileage of the auxiliary tunnel.

[0095] The embodiment provides a method for determining an auxiliary tunnel center mileage based on optimization, and the method comprises the following steps: acquiring tunnel engineering data, and determining the number of construction work areas according to the tunnel engineering data, so as to improve the accuracy of the number of construction work areas; determining a tunnel reference construction period under the auxiliary tunnel based on the number of construction work areas, so as to quickly and accurately determine the tunnel reference construction period; determining an initial center mileage of the auxiliary tunnel based on the tunnel reference construction period, so as to improve the optimization efficiency; acquiring an actual tunnel construction period under the auxiliary tunnel, and optimizing the initial center mileage based on the actual tunnel construction period, so as to obtain a target center mileage of the auxiliary tunnel, and the target center mileage can be used to quickly and accurately locate the center mileage of the auxiliary tunnel, thereby effectively improving the auxiliary tunnel scheme design efficiency.

[0096] In conclusion, the reference construction period is determined by determining the number of construction work areas, the initial center mileage is determined and optimized to obtain the target center mileage, the initial center mileage is quickly determined based on the number of construction work areas and is continuously optimized, the center mileage of the auxiliary tunnel can be quickly and accurately located, the technical defect of low auxiliary tunnel scheme design efficiency is overcome, and the auxiliary tunnel scheme design efficiency can be effectively improved.

[0097] Based on the first embodiment of the application, in the second embodiment of the application, the same or similar contents as the above-mentioned first embodiment can be referred to the above description, and the subsequent description will not be repeated. On this basis, please refer to Figure 5 , the step S10 further comprises steps S101-S103:

[0098] In step S101, the tunnel overall construction period, the construction speed of each stratum in the tunnel range and the construction length of each stratum are determined according to the tunnel engineering data.

[0099] It should be noted that the tunnel engineering data at least comprises a tunnel overall construction period T s , a tunnel length L s , a construction speed V i of each stratum in the tunnel range, a length l i and a single auxiliary tunnel construction period T f , and the embodiment does not make specific limitation on this.

[0100] It can be understood that according to the tunnel overall construction period, in combination with the construction speed V i of each stratum in the tunnel range and the length l i , the entire tunnel is processed by slicing according to the tunnel overall construction period T s , a local optimal solution of the number of construction work areas under this construction period is obtained according to the number of slices, and the number of construction work areas is preliminarily obtained.

[0101] Step S102: Determine the construction time for each stratum based on the construction speed and construction length of each stratum.

[0102] It should be noted that, based on the construction speed V of each stratum within the tunnel area... i and length l i The construction time t for each stratum can be obtained. i , t i =V i / l i .

[0103] Step S103: Determine the number of construction zones based on the construction time of each stratum and the overall tunnel construction period.

[0104] It should be noted that, depending on the construction time t of each stratum, i And the overall construction period of the tunnel T s This allows us to determine the number of construction zones.

[0105] In practical implementation, the overall tunnel construction period T can be... s According to the construction time of each stratum t i The project is divided into sections, and the construction period for each section is determined. This determines the number of construction sections, and the time allotted for each section is the total construction period T. s It is the sum of the construction times Ti of each stratum according to the overall construction period T. s The number of work zones is obtained by dividing the area into zones. The number of work zones can also be determined by other methods, but this embodiment does not impose specific restrictions on this.

[0106] In one feasible implementation, step S103 may include: determining the number of strata and the tunnel length based on the tunnel engineering data; determining the one-way construction period based on the number of strata and the construction time of each stratum; and determining the number of construction zones based on the one-way construction period and the tunnel length.

[0107] It should be noted that the one-way construction period refers to the time required to start construction from one end of the tunnel and reach the other end. If the one-way construction period is less than or equal to the overall tunnel construction period, then one-way construction can meet the requirements of the overall tunnel construction period, and there is no need to increase the number of construction work areas. However, if the one-way construction period is greater than the overall tunnel construction period, then one-way construction cannot meet the requirements of the overall tunnel construction period, and it is necessary to consider increasing the number of construction work areas. In this case, two-way construction can be considered, that is, starting construction simultaneously from both ends of the tunnel, which can shorten the construction period.

[0108] It can be understood that if the two-way construction period is less than or equal to the overall tunnel construction period, the two-way construction can meet the requirement of the overall tunnel construction period, and in this case, the auxiliary tunnel does not need to be added. However, if the two-way construction period is still greater than the overall tunnel construction period, the auxiliary tunnel needs to be added in order to further shorten the construction period.

[0109] In a specific implementation, only the one-way construction is considered, if wherein, is the one-way construction period, the one-way construction can meet the overall tunnel construction period; if the one-way construction does not meet the overall construction period, the two-way construction is considered, if the two-way construction can meet the overall tunnel construction period, in this case, the auxiliary tunnel does not need to be added, if the auxiliary tunnel needs to be added.

[0110] In a feasible implementation, the construction work area quantity is determined according to the one-way construction period and the tunnel length, including: when the one-way construction period is greater than the overall tunnel construction period, the two-way construction period is determined according to the number of strata and the construction time of each stratum; when the two-way construction period is greater than the overall tunnel construction period, the construction work area boundary position and the construction work area boundary position quantity are determined according to the construction time of each stratum, the construction speed of each stratum, the construction length of each stratum and the preset construction period of a single auxiliary tunnel; the target position in the construction work area boundary position is compared with the tunnel length; when the target position in the construction work area boundary position reaches the tunnel length, the construction work area boundary position quantity is taken as the construction work area quantity.

[0111] It should be noted that the work area quantity is obtained by dividing the tunnel according to a certain period of time, and the position calculation is the tunnel length / work area quantity. In the calculation arrangement, the tunnel length can be certainly reached.

[0112] If the two-way construction does not meet the overall construction period, the auxiliary tunnel is considered to be constructed, when the first or last construction work area is calculated, the construction work area boundary position f(w) is as follows:

[0113]

[0114] In formula 1, f(w) is the current construction work area boundary position, f(w+1) is the next construction work area boundary position, t i is the construction time of stratum i, T s is the overall tunnel construction period, V i , l i are respectively the construction speed and length of each stratum in the tunnel range.

[0115] When calculating the remaining construction areas, the construction time of auxiliary tunnels must be taken into account, and the construction period T for each auxiliary tunnel should be set in advance. f If the construction time of the stratum is t i <T s -T f Then compare the construction time t of the next stratum. i+1 and The relationship between them. If the construction time t of the stratum... i >T s -T f Then it can be determined that there is a construction zone interface at the location of the i-th stratum, and its specific location is... The formula for calculating the location of the work area is as follows:

[0116]

[0117] In Equation 2, f(w) represents the current construction zone boundary position, f(w+1) represents the next construction zone boundary position, and t i T is the construction time for stratum i. s For the overall construction period of the tunnel, T f For the construction period of a single auxiliary tunnel, V i l i These represent the construction speed and length of each stratum within the tunnel area.

[0118] like Figure 6 As shown, Figure 6 This is a schematic diagram showing the connection point of the construction work area. The tunnel is divided into multiple construction work areas, and the construction period for each work area is t. The boundary of the construction work area is the connection point of the construction work area.

[0119] By traversing all geological strata within the tunnel, the number of iterations w (i.e., the number of construction work zone boundaries) and the value of f(w) can be obtained. The maximum value of f(w) can then be determined in relation to the tunnel length L. s Relationship, if f(w) < L s If the condition is met, the next iteration of the loop is required; otherwise, the loop is stopped. In this case, w represents the number of construction zones.

[0120] In a specific implementation, a certain tunnel is 14.116 km long, and the tunnel construction control period is 39 months. There are 8 strata in the tunnel range, and the tunnel construction speed and length in each strata are shown in Table 1. Table 1 is a table of construction information of each strata in the tunnel range, which includes the surrounding rock grade, construction speed (m / month), length (m), and event (month). For example, when the surrounding rock grade is 5, the construction speed is 65, the length is 512, and the time is 7.88. The initial construction period of the auxiliary tunnel is about 1.5 months, the starting mileage of the entrance is DK279+314, and after calculation, the preliminary construction work area is obtained, the number of which is 3, and the number of preliminary construction work area boundaries is 2, as shown in Figure 7 Figure 7 which is a schematic diagram of the number of preliminary construction work areas. The number of preliminary work areas is odd, so the number of auxiliary tunnels is 1, and the optimized construction work area is 28.8 months, which is less than the construction period of 39 months and meets the requirements. According to the number of auxiliary tunnels and the recalculated construction period, the position of the auxiliary tunnel is obtained, as shown in Figure 8 Figure 8 which is a schematic diagram of the position of the auxiliary tunnel and the construction work area. According to the calculation, the distance between the auxiliary tunnel and the starting entrance is 6.581Km, the mileage is DK285+895, and the positions of the two construction work areas are 2.755Km and 10.36Km, respectively, and the mileages are DK282+069 and DK289+674, respectively. The above data are all less than the total length of the tunnel 14.116Km, which meets the design requirements. The actual auxiliary tunnel construction period of 4.5 months is input at the position, and the updated auxiliary tunnel position is updated, as shown in Figure 9 Figure 9 which is a schematic diagram of the updated auxiliary tunnel and the position of the construction work area. After calculation, the actual construction period is 30.3 months, which is less than the required construction period of 39 months. The distance between the auxiliary tunnel and the starting entrance is 6.581Km, the mileage is DK285+895, and the positions of the two construction work areas are 2.98Km and 10.22Km, respectively, and the mileages are DK282+294 and DK289+534, respectively. The above data are all less than the total length of the tunnel 14.116Km, which meets the design requirements.
