Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to an emergency water discharge structure and its design, layout and use methods. Background Technology

[0002] Aqueducts, as the most widely used intersecting structures in irrigation projects, are characterized by their "top-heavy" nature, which is extremely detrimental to their seismic resistance. Taking earthquake disasters as an example, if the water in the aqueduct is regulated before the arrival of the destructive S-wave, it could significantly reduce the bending moment at the pier base, lower the structural response of the aqueduct under strong earthquakes, and mitigate earthquake damage. However, the opening and closing speeds of existing spillway gates (electric, hydraulic, and manual) are typically on the order of minutes, while the effective window for earthquake early warning is only 10-30 seconds. This significant time difference prevents proactive disaster mitigation using early warning information. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the opening and closing time of existing aqueduct spillway gates is much longer than the effective window time for earthquake early warning. The purpose is to provide an emergency spillway structure and its design, deployment and use method to solve the above-mentioned problem.

[0004] This invention is achieved through the following technical solution:

[0005] In a first aspect, the present invention provides an emergency drainage structure, including an aqueduct, a drainage channel, and a control module;

[0006] The aqueduct is equipped with a drain outlet for emergency water discharge;

[0007] The drainage channel is set on the drainage outlet of the aqueduct and is used to control the opening and closing of the drainage outlet. The drainage channel includes multiple sealing layers arranged sequentially along the height direction of the drainage outlet, and adjacent sealing layers are connected by explosive bolts.

[0008] The control module is installed on the aqueduct and is used to control the detonation of the explosive bolts.

[0009] In one possible design, there are multiple drainage outlets, and correspondingly, the aqueduct is divided into several sections with the drainage outlets as boundaries; each drainage outlet is provided with a drainage channel, and correspondingly, there are multiple drainage channels, each corresponding to one of the drainage outlets.

[0010] The drainage channel includes several hinged plates arranged sequentially along the height of the aqueduct. Adjacent hinged plates are connected by explosive bolts, and the hinged plates serve as a sealing layer.

[0011] Secondly, the present invention provides a design method for the aforementioned emergency drainage structure, comprising the following steps:

[0012] Based on the relationship between water volume and depth within the aqueduct and the relationship between the outflow rate from the aqueduct's spillway and water depth, the rate of change of water depth within the aqueduct is obtained.

[0013] By integrating the rate of change of water depth in the aqueduct, the relationship between the water depth in the aqueduct and time can be obtained.

[0014] By substituting specific point values ​​into the relationship between the water depth in the aqueduct and time, the total width of the aqueduct's spillway can be obtained.

[0015] In one possible design, specific points include time zero and its water level, as well as time for the aqueduct to discharge water and reach a safe water depth and a safe water level.

[0016] In one possible design, the formula for calculating the time it takes for the aqueduct to discharge water and reach a safe water depth is obtained based on the ratio of the straight-line distance from the engineering site to the fault segment most likely to experience an earthquake exceeding the design seismic intensity, as determined during the exploration phase, to the propagation velocity of the seismic S-wave.

[0017] Accordingly, the formula for calculating the time it takes for the aqueduct to discharge water and reach a safe water depth is used to calculate the coefficients in the relationship between the water depth in the aqueduct and time.

[0018] Thirdly, this invention provides a method for deploying an emergency drainage structure based on the design method of an emergency drainage structure, comprising the following steps:

[0019] Based on the calculation formula for the time it takes for the aqueduct to discharge water and reach a safe water depth, the time it takes for an earthquake exceeding the design intensity to reach the engineering site is determined.

[0020] Substituting the time of zero and the time of water discharge from the aqueduct to reach a safe water depth into the relationship between the water depth in the aqueduct and time, the total width of the aqueduct's discharge outlet is determined.

[0021] Based on the overall structural layout of the aqueduct, the drainage channel was located at the position that would have the least impact on the area below the aqueduct.

[0022] Determine the width of each individual drainage channel until the total width of all drainage channels reaches the calculated total width of the aqueduct drainage outlet;

[0023] Draw a distribution map of the drainage channels and drawings of the aqueduct pier top modification.

[0024] Fourthly, the present invention provides a method for using the aforementioned emergency drainage structure, comprising the following steps:

[0025] Early warning signal reception and processing;

[0026] Signal analysis and flood discharge plan generation;

[0027] The drainage channel was blasted open and water was released.

[0028] Real-time water level monitoring and processing;

[0029] Follow-up processing.

[0030] In one possible design, based on the reception and processing of early warning signals, the following is included:

[0031] By monitoring and receiving seismic wave signals through the earthquake early warning system, the earthquake intensity, the actual distance from the epicenter to the aqueduct site, and the dominant frequency can be obtained.

[0032] Based on signal analysis and flood discharge scheme generation, including:

[0033] Determine whether the intensity of the earthquake is greater than the seismic design intensity. If it is less than the seismic design intensity, emergency water discharge is not triggered. If it is greater than the seismic design intensity, emergency water discharge is triggered. Based on the seismic design intensity of the aqueduct, determine the optimal seismic water level and select the optimal combination of water discharge channels to generate an emergency water discharge trigger signal.

[0034] In one possible design, based on the explosive opening of the drainage channel and the release of water, the following is included:

[0035] The control module receives the emergency water discharge trigger signal and initiates the blasting, opening the sealing layer of the water discharge channel and releasing water;

[0036] Based on real-time water level monitoring and processing, including:

[0037] The system monitors water level changes in the aqueduct in real time and compares them with updated seismic signals, adjusting the number of sealing layers opened on the spillway as needed; and the sealing layers are opened one by one from top to bottom.

[0038] In one possible design, based on subsequent processing, including:

[0039] Post-earthquake structural inspection; replacement of explosive bolts; replacement and repair of drainage channels; testing and acceptance.

[0040] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0041] 1. Rapid response: The action time of the explosive bolt is in the millisecond range, and the entire water release process is completed within a few seconds, perfectly matching the earthquake early warning window.

[0042] 2. Precise control: The drainage channel is designed with multiple sealing layers to achieve "discharge on demand" rather than completely emptying, maximizing the protection of water resources and reducing the impact.

[0043] 3. Safe and reliable: The aqueduct is no different from existing aqueducts under normal use; it can operate reliably in emergencies.

[0044] 4. High cost-effectiveness: The structure is simple and easy to modify, avoiding huge risks of damage to the main structure with minimal modification costs. Attached Figure Description

[0064] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0065] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to practice the invention. In other embodiments, well-known structures, circuits, materials, or methods have not been specifically described in order to avoid obscuring the invention.

[0066] Example 1:

[0067] like Figures 1-4 As shown, an emergency water discharge structure includes an aqueduct 100, a water discharge channel 200, and a control module 300.

[0068] The aqueduct 100 is equipped with a drain outlet for emergency water discharge;

[0069] The drainage channel 200 is set on the drainage outlet of the aqueduct 100 and is used to control the opening and closing of the drainage outlet. The drainage channel 200 includes multiple sealing layers 201 arranged sequentially along the height direction of the drainage outlet, and adjacent sealing layers 201 are connected by explosive bolts 202.

[0070] The control module 300 is mounted on the aqueduct 100 and is used to control the detonation of the explosive bolts 202.

[0071] Aqueduct 100 is an overhead water conveyance structure, such as Figure 1 As shown, a support pier 400 is also provided below it. When the aqueduct 100 is used for emergency water discharge, it is equipped with a suitable drainage outlet. Preferably, as shown... Figure 1 As shown, multiple drainage outlets are provided to improve the drainage capacity of the aqueduct 100. Correspondingly, each drainage outlet is provided with a drainage channel 200.

[0072] Under normal circumstances, the sealing layer 201 of the discharge channel 200 blocks the aqueduct 100 to prevent water from flowing out of the discharge outlet and ensure that the water flows in the designed direction. At this time, the sealing layer 201 acts as a sealing gate for the discharge.

[0073] In special circumstances such as earthquakes, the aqueduct 100 needs to quickly discharge water. At this time, the control module 300 controls the explosive bolts 202 to detonate, and the connection between the sealing layers 201 is released, so that the sealing layers 201 rotate under the impact of the water and open the water discharge channel 200. The water can flow out of the aqueduct 100 from the discharge port, realizing the rapid opening and rapid discharge of the water discharge channel 200. It can respond quickly within the warning period of special circumstances and reduce the damage to the aqueduct 100.

[0074] It is worth noting that there are multiple sealing layers 201 in the same drainage channel 200. The control module 300 can control the number of sealing layers 201 that are opened as needed. The drainage flow rate is controlled by controlling the drainage height of the drainage outlet. This achieves rapid drainage while also enabling stratified drainage, effectively controlling the drainage flow rate to reduce the impact of water on the aqueduct 100 during the drainage process and reduce the damage to the aqueduct 100.

[0075] Therefore, the number of open drainage channels 200 and the number of open sealing layers 201 in a single drainage channel 200 are the key factors determining the drainage flow rate of the aqueduct 100.

[0076] As is easily understood, the control module 300 can be any suitable existing model, and the control module 300 is connected to the early warning system. The early warning system is used to monitor any unexpected disasters such as earthquakes, formulate a water release plan according to the disaster situation and send out signals in a timely manner. After receiving the signal, the control module 300 promptly controls the corresponding explosive bolt 202 to detonate.

[0077] In one possible implementation, there are multiple drainage outlets, and the aqueduct 100 is divided into several sections with the drainage outlets as boundaries; each drainage outlet is provided with a drainage channel 200, and there are multiple drainage channels 200, which are set one-to-one with the drainage outlets.

[0078] Therefore, for the drainage outlets, their height is equal to the height of the aqueduct 100, and their width is parallel to the water flow direction of the aqueduct 100. Multiple drainage outlets are provided, and during emergency drainage operations, the total width of the drainage outlets equals the sum of the widths of the open drainage outlets. It is easy to understand that if a drainage outlet is blocked by the drainage channel 200, then the width of a single drainage outlet equals the width of the drainage channel 200. Therefore, the total width of the drainage outlets equals the sum of the widths of the open drainage outlets equals the sum of the widths of the open drainage channel 200.

[0079] Meanwhile, since the drainage channel 200 includes multiple sealing layers 201, the height of the corresponding drainage outlet for drainage is limited by the sealing layers 201. That is, the sum of the heights of the multiple sealing layers 201 equals the height of the corresponding drainage outlet. By opening the sealing layers 201 one by one from top to bottom, layered drainage can be achieved, and the drainage flow rate can be controlled more precisely.

[0080] Based on this, the early warning system should formulate a drainage plan based on two factors: the number of drainage channels 200 that are opened and the number of sealing layers 201 that are opened in a single drainage channel 200.

[0081] In one possible implementation, the drainage channel 200 includes a plurality of hinged plates arranged sequentially along the height of the aqueduct 100, with adjacent hinged plates connected by expansion bolts 202, and correspondingly, the hinged plates serve as a sealing layer 201.

[0082] Based on the above design, the hinge plate has a hinge portion 203 hinged to the aqueduct 100 and a detachable portion 204 connected to adjacent components via expansion bolts 202. The hinge portion 203 is connected by any suitable existing hinge portion 203 component. The adjacent components connected to the detachable portion 204 include, but are not limited to, the inner wall of the aqueduct 100 and adjacent hinge plates. When the drainage channel 200 blocks the aqueduct 100, both the hinge portion 203 and the detachable portion 204 remain connected; conversely, when the drainage channel 200 is opened, the detachable portion 204 is disconnected, and the hinge plate rotates around the hinge portion 203 under the impact of water.

[0083] For a single sealing layer 201, it may include a hinged plate, one side of which is connected to the inner wall of the aqueduct 100 via a hinge portion 203, and the other side of which is connected to the inner wall of the aqueduct 100 via a detachable portion 204. The upper and lower ends of the hinged plate are also connected to adjacent hinged plates via expansion bolts 202. Alternatively, as... Figure 3As shown, it may also include two hinged plates. One side of a single hinged plate is connected to the inner wall of the aqueduct 100 via a hinge portion 203, and the other side of the hinged plate is connected to a hinged plate of the same sealing layer 201 via a detachable portion 204. The upper and lower ends of the hinged plates are also connected to adjacent hinged plates via expansion bolts 202. In other words, a single sealing layer 201 has a single-opening structure including one hinged plate and a split structure having two hinged plates, or it can be constructed as any other suitable structure for selection by those skilled in the art.

[0084] It is worth noting that by setting multiple sealing layers 201 sequentially from top to bottom, layered drainage is achieved, and the specific number of sealing layers 201 can be increased or decreased as needed, making the design more flexible. For example, such as Figure 4 As shown, the drainage channel 200 has three sealing layers 201 from top to bottom. From left to right, the states of one of the drainage outlets on the drainage channel 200 are shown when the sealing layer 201 is opened by one (i.e., first-level drainage), two (i.e., second-level drainage), and three (i.e., third-level drainage).

[0085] Example 2:

[0086] In a first aspect, the present invention provides a design method for the aforementioned emergency drainage structure, comprising the following steps:

[0087] S10 is based on the relationship between water volume and depth within the aqueduct. Relationship between the outflow rate from the aqueduct spillway and water depth Obtain the rate of change of water depth within the aqueduct .

[0088] S20 rate of change of water depth in the aqueduct By performing integration, the relationship between the water depth in the aqueduct and time can be obtained. .

[0089] S30 substitutes specific point values ​​into the relationship between the water depth in the aqueduct and time. , obtain the total width b of the aqueduct outlet.

[0090] Where, d - differential sign; f(h) - function relating the cross-sectional area of ​​the aqueduct to the water depth h; L - total length of the aqueduct; V - water volume of the aqueduct; h - water level of the aqueduct; t - time; q - discharge flow rate; b - total width of the aqueduct outlet; C - integral constant related to the initial conditions;

[0091] Therefore, a design method for aqueducts is presented. Below, based on the above design concept, taking a square-section aqueduct as an example, an application of the design method for the emergency drainage structure is given, which includes the following steps:

[0092] S10 is based on the relationship between water volume and depth within the aqueduct. Relationship between the outflow rate from the aqueduct spillway and water depth Obtain the rate of change of water depth within the aqueduct .

[0093] S20 rate of change of water depth in the aqueduct By performing integration, the relationship between the water depth in the aqueduct and time can be obtained. .

[0094] S30 substitutes specific point values ​​into the relationship between the water depth in the aqueduct and time. , obtain the total width b of the aqueduct outlet.

[0095] Where d is the differential symbol; L is the total length of the aqueduct; B is the width of the aqueduct; V is the water volume of the aqueduct; h is the water level of the aqueduct; t is the time; q is the discharge flow rate; b is the total width of the aqueduct outlet; and C is the integral constant related to the initial conditions.

[0096] For step S30, step S30 includes:

[0097] S31 obtains specific points: these specific points include time zero and its water level, as well as time for the aqueduct to discharge water and reach a safe water depth and a safe water level. Based on this, Indicates that the time is zero, with The water level at time zero is represented by... Indicates the time it takes for the aqueduct to discharge water and reach a safe water depth, in... If the safe water level (i.e., the optimal water level for seismic resistance of the aqueduct) is represented, then the two specific points mentioned above can be represented as ( , )and( , ).

[0098] The formula for calculating the time it takes for S32 to discharge water from the aqueduct and reach a safe water depth is based on the straight-line distance from the engineering site determined during the exploration phase to the fault segment most likely to experience an earthquake exceeding the design seismic intensity. The ratio of the propagation velocity of the seismic S-wave to the time it takes for the aqueduct to discharge water and reach a safe water depth is used to calculate the time. ;

[0099] Accordingly, the formula for calculating the time it takes for the aqueduct to discharge water and reach a safe water depth is as follows. The coefficient C is used to calculate the relationship between water depth and time in the aqueduct; k is the epicenter deviation coefficient, which can be taken as 1.0~2.5 according to the actual situation during design.

[0100] Secondly, the present invention also provides a hardware device for implementing the design method of the emergency drainage structure, comprising:

[0101] First calculation unit: used to obtain the rate of change of water depth in the aqueduct based on the relationship between water volume and depth in the aqueduct and the relationship between the outflow from the aqueduct outlet and water depth.

[0102] The second calculation unit is used to integrate the rate of change of water depth in the aqueduct to obtain the relationship between the water depth in the aqueduct and time.

[0103] The third calculation unit: by substituting specific point values ​​into the relationship between the water depth in the aqueduct and time, the total width of the aqueduct's spillway is obtained.

[0104] The working process, working details and technical effects of the device provided in this embodiment can be found in the first aspect of this embodiment, and will not be repeated here.

[0105] Thirdly, the present invention provides a device comprising a memory, a processor, and a transceiver connected in sequence and communication, wherein the memory is used to store a computer program, the transceiver is used to send and receive messages, and the processor is used to read the computer program and execute the design method of the emergency drainage structure.

[0112] Example 3:

[0113] In a first aspect, the present invention provides an emergency drainage structure layout method based on an emergency drainage structure design method, comprising the following steps:

[0115] S20 time is zero and time is the time it takes for the aqueduct to discharge water and reach a safe water depth [i.e. ( , )and( , Substitute the two points into the relationship between the water depth in the aqueduct and time. Determine the total width b of the aqueduct's outlet.

[0116] S30, based on the overall structural layout of the aqueduct, selects the location with the least impact on the area below the aqueduct for the placement of the drainage channel. Specifically, depending on the aqueduct layout, an open area can be selected for drainage, and the drainage channel can be installed at the corresponding location. It is readily understood that those skilled in the art can determine the location of the drainage channel based on existing drainage standards, specifications, and other relevant documents.

[0130] In summary, the aqueduct is designed according to the design method for the aforementioned emergency drainage structure, enabling it to achieve the expected drainage capacity. The design values ​​obtained through this method are used to plan the layout of the aqueduct, or to modify an existing aqueduct by installing drainage channels at the required locations to form the emergency drainage structure.

[0131] Example 4:

[0132] Taking the aforementioned emergency water discharge structure for earthquake disaster relief as an example, firstly, such as Figure 5 As shown, the present invention provides a method for using the aforementioned emergency drainage structure, comprising the following steps:

[0133] S10 Early Warning Signal Reception and Processing: After an earthquake occurs, the earthquake early warning system monitors and receives seismic wave signals to obtain the earthquake intensity, the actual distance from the epicenter to the aqueduct site, and the dominant frequency.

[0134] The early warning system also needs to preprocess the received information (mainly earthquake intensity, epicenter distance, and dominant frequency) to facilitate faster generation of flood discharge plans. Therefore, the early warning system can select the appropriate model based on the type of disaster to improve the accuracy of the warning. Furthermore, for earthquake disasters, in addition to the aforementioned earthquake intensity, actual distance from the epicenter to the aqueduct site, and dominant frequency, the earthquake early warning system can also receive any other suitable information to provide more reference data for flood discharge plans.

[0135] S20 Signal Analysis and Flood Discharge Scheme Generation: Determine whether the intensity of this earthquake is greater than the seismic design intensity. If it is less than the seismic design intensity, emergency water discharge is not triggered; if it is greater than the seismic design intensity, emergency water discharge is triggered. Based on the seismic design intensity of the aqueduct, determine the optimal seismic water level and select the optimal combination of water discharge channels to generate an emergency water discharge trigger signal.

[0136] The early warning system includes a contingency plan database. Upon receiving disaster information, based on the seismic wave signal and the seismic water level determined by the previous contingency plan, the corresponding flood discharge plan in the contingency plan database is directly selected according to the disaster intensity (the flood discharge plan includes the optimal seismic water level and the optimal combination of water discharge channels), which further improves the response speed of the early warning system and shortens the time for the emergency water discharge structure to open the water discharge channel.

[0137] It is worth noting that when a disaster occurs, if its intensity does not trigger emergency water release, the early warning system should increase the detection frequency.

[0138] S30 drainage channel blasting opens and releases water: The control module receives the emergency drainage trigger signal and initiates blasting, opening the sealing layer of the drainage channel and releasing water.

[0139] Upon receiving an emergency water release trigger signal, the control module initiates blasting according to preset logic, causing the corresponding explosive bolts to detonate and open the sealing layer (the sealing layer is...). Figure 5 The layered water-blocking connection structure described herein allows the drainage channel to open and drain water.

[0140] S40 Water Level Real-time Monitoring and Processing: Real-time monitoring of water level changes in the aqueduct and comparison with updated seismic signals; adjusting the number of sealing layers opened on the spillway as needed; and opening the sealing layers one by one from top to bottom.

[0141] This means that the early warning system keeps working and updates disaster-related information, obtains the optimal seismic water level of the aqueduct for the corresponding time period, and adjusts the drainage area of ​​the aqueduct in a timely manner.

[0142] The logic for adjusting the spillway is as follows: based on the updated seismic signal, determine whether the aqueduct has reached the optimal seismic water level. If so, maintain the current spillway status until the next seismic signal update. If not, determine the optimal seismic water level and select the optimal spillway combination, generate an emergency spillway trigger signal, and thereby adjust the width and depth of the spillway.

[0143] S50 follow-up procedures: post-earthquake structural inspection; replacement of explosive bolts; replacement and repair of drainage channels; testing and acceptance.

[0145] Early warning signal receiving and processing unit;

[0146] Signal analysis and flood discharge scheme generation unit;

[0147] The drainage channel was blasted open, and the drainage unit was activated.

[0148] Real-time water level monitoring and processing unit;

[0149] Subsequent processing unit.

[0152] The working process, working details and technical effects of the device provided in this embodiment can be found in the first aspect of this embodiment, and will not be repeated here.

[0153] Fourthly, the present invention provides a storage medium for storing a method of using the emergency drainage structure described in the first aspect of the embodiments, wherein the storage medium stores instructions that, when the instructions are executed on a computer, execute the method of using the emergency drainage structure.

[0154] Fifthly, the present invention provides a computer program product containing instructions that, when executed on a computer, cause the computer to perform a method for using the emergency drainage structure. The computer may be a general-purpose computer, a special-purpose computer, a computer network, or other programmable device.

[0155] Example 5:

[0156] This embodiment, based on embodiments 1-4, verifies the effectiveness of an emergency drainage structure applying the design, layout, and usage methods of the described emergency drainage structure. Specifically:

[0157] According to the standard "Standard for Seismic Design of Hydraulic Structures" (GB51247-2018), for seismic calculations of aqueducts of seismic grade 3 and below, a quasi-static method can be used to perform seismic calculations on the aqueduct piers and aqueduct body model. The load diagrams of the aqueduct pier model under longitudinal and transverse seismic loads are shown below. Figure 6 and Figure 7 As shown.

[0158] Wherein, P1 and P2 are the vertical loads transmitted by the final load of the upper trough shell under seismic load; Q (Q1) is the seismic force transmitted by the upper trough body and top beam (the seismic force of the top beam is evenly distributed to nodes 1 and 5); Q2 and Q3 are the seismic forces of the crossbeams (the seismic forces of each crossbeam are evenly distributed to the corresponding nodes of the crossbeams); q 震1 -q 震4 M is the seismic force of the column (the seismic force of the column is a uniformly distributed load with a trapezoidal distribution); M is the longitudinal bending moment transmitted by the upper trough.

[0159] To verify the impact of changes in water volume within the trench on the ground force and moment of the pier, based on the calculation and analysis of the above-mentioned actual cases, the specific values ​​of each load under longitudinal and transverse seismic action can be obtained for the trench pier model under the two working conditions of design water level and empty trench, as shown in the table below.

[0164] Based on the above calculations of the specific values ​​of various loads on the pier model under longitudinal and transverse seismic loading under the two water level conditions, the bending moment, shear force, and axial force under longitudinal and transverse seismic loading under different conditions can be compared using analysis software, as shown in the following figures. Figures 8-13 As shown.

[0165] Depend on Figures 8-13The comparison of bending moment, shear force, and axial force under transverse seismic loading with and without a design water level shows that the internal force response at the pier base is significantly reduced under the empty trench condition compared to the design water level condition. Specifically, the bending moment at the pier base decreases from 928 kN·m to 590 kN·m, a reduction of 36%; the shear force at the pier base decreases from 301 kN to 194 kN, also a reduction of 36%; and the maximum axial force at the pier base decreases from 2850 kN to 1734 kN, a reduction of 39%. These data indicate that under transverse seismic loading, lowering the water level in the trench can significantly reduce the bending moment, shear force, and axial force at the pier base section, thereby significantly reducing the adverse effects of seismic loading on the pier structure, improving the seismic performance of the structure, and mitigating potential damage. This result has reference value for the seismic design and safety control of similar hydraulic or bridge engineering structures, demonstrating that the dynamic response of the structure can be optimized by reasonably controlling the water level.

[0166] Depend on Figures 14-16 The comparison of bending moment, shear force, and axial force under longitudinal seismic loading with and without a design water level shows that the internal force response at the pier base is significantly reduced under the empty trench condition compared to the design water level condition. Specifically, the bending moment at the pier base decreases from 1820 kN·m to 1193 kN·m, a reduction of 34%; the shear force at the pier base decreases from 187 kN to 130 kN, a reduction of 30%; and the axial force at the pier base decreases from 1296 kN to 779 kN, a reduction of 40%. These data also indicate that under longitudinal seismic loading, lowering the water level in the trench can significantly reduce the bending moment, shear force, and axial force at the pier base section, thereby significantly reducing the adverse effects of seismic loading on the pier structure, improving the seismic performance of the structure, and mitigating potential damage. This result has reference value for the seismic design and safety control of similar hydraulic or bridge engineering structures, demonstrating that the dynamic response of the structure can be optimized by reasonably controlling the water level.

[0167] In summary, lowering the water level in the trench significantly reduces the bending moment, shear force, and axial force at the pier base under both lateral and longitudinal seismic loading, with reductions reaching 30% to 40%. This result demonstrates that rationally controlling the water level is an effective measure to optimize the dynamic response of the structure, significantly improving the seismic performance of piers and mitigating potential earthquake damage. It provides valuable practical reference for seismic design and safety control in hydraulic engineering and bridge construction.
