Description

Technical Field

[0001] This application relates to the technical field of rock and soil earthquake experiments. Specifically, it relates to a seismic motion simulation test device for gently inclined bedding rock slopes. Background Art

[0002] Gently inclined bedding rock slopes widely exist in terrain areas such as mountainous areas and hilly areas. With the continuous advancement of infrastructure construction, a large number of engineering activities involve such slopes. However, seismic activities pose a serious threat to the stability of gently inclined bedding rock slopes. During an earthquake, the generated seismic waves will cause the vibration of the slope rock and soil mass, resulting in a change in the internal stress state of the rock and soil mass, and then may trigger slope instability, causing geological disasters such as landslides and collapses, causing great damage to surrounding buildings, transportation facilities, and the safety of personnel. For example, in the construction of some mountain roads, if the stability of gently inclined bedding rock slopes under seismic action is not fully considered, once an earthquake occurs, slope instability may block traffic, causing serious economic losses and casualties. Therefore, seismic motion simulation tests for gently inclined bedding rock slopes are particularly important.

[0003] However, during the use of existing seismic motion simulation test devices for gently inclined bedding rock slopes, most can only vibrate the model storage box in one direction or two directions. However, in actual earthquakes, the slopes are subjected to complex multi-dimensional vibrations, including combinations of vertical, horizontal, and longitudinal vibrations, etc. The vibration simulation in only one direction or two directions cannot truly restore the complexity of seismic motion, ignoring the coupling effect between vibrations in different directions, and thus affecting the accuracy of the experiment, which is not conducive to accurately evaluating slope stability. Summary of the Invention

For this reason, this application proposes a seismic motion simulation test device for gently inclined bedding rock slopes. The seismic motion simulation test device for gently inclined bedding rock slopes generates vertical and horizontal vibrations of the model storage box through the cooperation of a cam and a vibration plate, and a pressing seat and a vibration convex seat, restores the multi-dimensional vibration scenario, and at the same time, by means of the inclination of the vibration plate and the corner jacking, simulates the different forces and uneven vibrations of the slope during an earthquake, effectively presenting the complex stress state and response characteristics of the slope in actual earthquakes.

[0021] The beneficial effects of the present application are as follows: During use, the vertical vibration mechanism drives the horizontal vibration mechanism to cause the model storage mechanism to generate horizontal vibration. At the same time, the vibration position adjusting mechanism moves horizontally back and forth under the drive of the horizontal vibration mechanism and intermittently lifts the corner of the model storage mechanism, thereby changing the vibration position of the vertical vibration mechanism. Through the coordinated action of each mechanism, the multi-dimensional vibration and uneven vibration conditions of the gently inclined bedding rock slope during an earthquake are simulated, improving the accuracy of the earthquake motion simulation test of the gently inclined bedding rock slope. Among them, by starting one servo motor, various vibrations of the model storage box can be realized. First, the model storage box can generate vertical and horizontal vibrations simultaneously. The vertical vibration is generated by the cooperation of the cam and the vibration plate, and the horizontal vibration is generated by the cooperation of the pressing seat and the vibration convex seat. Acting together with the vertical vibration, it truly restores the complex multi-dimensional vibration conditions suffered by the slope during an earthquake. Second, the inclined state of the front end of the vibration plate being high and the rear end being low and the uneven vibration distribution effectively simulate different stress conditions of the slope during an earthquake. The larger vertical displacement and acceleration at the front end and the relatively smaller vertical movement at the rear end conform to the differences in the influence of the actual seismic wave on different parts of the slope. Third, during the vibration of the vibration plate, one corner can be intermittently lifted by the upper lifting frustum, changing the vibration position and vibration effect of the vertical vibration mechanism, which is more in line with the uneven vibration conditions in actual earthquakes. Fourth, the model storage box can generate vertical, horizontal and specific inclined vibrations. By the cooperation of multiple components, multi-dimensional vibrations are restored, stress differences and uneven vibrations are simulated, greatly improving the accuracy of the earthquake motion simulation test of the gently inclined bedding rock slope. Fifth, the multi-source vibration conditions in an earthquake are simulated, which can cover complex vibration combinations such as shear waves, longitudinal waves and their reflections and refractions in different geological media, and are no longer limited to simple single-direction or double-direction vibrations, thus highly restoring the real vibration environment of the slope during an earthquake.

The upper end of the fixing frame 223 is fixedly connected with an extrusion plate 225 at one end away from the middle of the connecting plate 103. The upper surface of the extrusion plate 225 cooperates with the lower surface of the adjusting convex plate 220. The vibration box 209 and the adjusting box 217 are located at the lower ends of the vibration plate 105 and the model storage box 110. The upper end of the reciprocating short screw 202 is rotatably connected to the lower surface of the connecting plate 103. The adjusting convex plate 220 reciprocates up and down inside the adjusting groove 218. A slide groove 224 is provided at one end of the adjusting box 217 close to the middle of the connecting plate 103. The extrusion plate 225 reciprocates laterally inside the slide groove 224. During the reciprocating movement of the adjusting convex plate 220, the vibration plate 105 is lifted. Specifically, in the seismic simulation test of the gently inclined rock slope,First, start the servo motor 201 to make the rectangular reciprocating slider 203 start to perform up and down reciprocating linear motion under the rotational drive of the reciprocating short screw 202. At the same time, the fixed plate 204 drives the mounting box 205 to also perform up and down reciprocating linear motion synchronously. At this time, the toothed cylinder 208 on the outer wall of the first rotating rod 207 meshes with the toothed plate 206. When the mounting box 205 moves up and down, the toothed cylinder 208 rolls along the toothed plate 206 and drives the first rotating rod 207 to rotate. The first transmission wheels 212 on the front and rear outer walls of the first rotating rod 207 and the middle second rotating rod 210 rotate synchronously through the first toothed belt 213. At the same time, the second transmission wheels 214 on the outer walls of the two side second rotating rods 210 also rotate synchronously through the second toothed belt 215. When the second rotating rod 210 rotates, the cam 211 on its outer wall also rotates accordingly. During the rotation process, the cam 211 contacts the lower surface of the vibrating plate 105, thereby achieving the purpose of jacking up the vibrating plate 105 and causing the vibrating plate 105 to generate vertical vibration. At the same time, since the reciprocating distance of the rectangular reciprocating slider 203 on the outer wall of the reciprocating short screw 202 is relatively short, under the meshing of the toothed plate 206 and the toothed cylinder 208, the first rotating rod 207 rotates reciprocally for half a week. At the same time, the second rotating rod 210 rotates synchronously with the first rotating rod 207. Therefore, the rotation period of the cam 211 is also half a week. After jacking up the vibrating plate 105, it will return to its original position under the action of the second rotating rod 210. At the same time, the vibrating plate 105 is connected to the connecting plate 103 through the reset thick spring 104. The reset thick spring 104 plays a role in resetting during the vibration process, enabling the vibrating plate 105 to vibrate continuously and stably. At the same time, when the rectangular reciprocating slider 203 moves upward, it will also drive the one-way lead screw 221 to rotate. At this time, the front one-way slider 222 will drive the fixed frame 223 and the pressing plate 225 to move inside the sliding groove 224 and jack up the adjusting convex plate 220 upward. At the same time, the rear one-way slider 222 will drive the fixed frame 223 and the pressing plate 225 to leave the inside of the sliding groove 224, and the adjusting convex plate 220 will return to its original position under the action of the short reset spring 219. At this time, the overall vibrating plate 105 is at an angle with the front end higher and the rear end lower. At this time, at the relatively high front position of the vibrating plate 105 under the jacking action of the cam 211, it will obtain a larger vertical displacement and acceleration compared to the rear end. At the same time, the relatively low rear position will experience a relatively small vertical movement, thus forming a non-uniform vibration distribution, further simulating the differences in the vibration wave effects on different parts of the slope during an earthquake, and further promoting more realistic deformation and dislocation of the bedding rock mass structure.

[0055] Such as Figure 12 , Figure 13 and Figure 14As shown, the lateral vibration mechanism 3 includes a first bevel gear 301, which is fixedly connected to the outer wall of the lower end of the reciprocating short screw 202. On both sides of the middle of the upper surface of the bottom plate 101, there are rotatably connected third rotating rods 302. At one end of each of the third rotating rods 302 close to the reciprocating short screw 202, there is fixedly connected a fourth bevel gear 314, and the fourth bevel gear 314 meshes with the first bevel gear 301. At the other end of each of the third rotating rods 302 away from the reciprocating short screw 202, there is fixedly connected a second bevel gear 303. On one side of the front end and the back end of the upper surface of the bottom plate 101, there are respectively rotatably connected reciprocating long screws 304. At one end of each of the reciprocating long screws 304 close to the third rotating rod 302, there is fixedly connected a third bevel gear 305, and the second bevel gear 303 meshes with the third bevel gear 305. A circular reciprocating slider 306 is sleeved on the rod body of the reciprocating long screw 304. On the upper surface of the circular reciprocating slider 306, there is fixedly connected a limiting shell 307. Inside the limiting shell 307, there is arranged a pressing seat 308. On the outer walls of both sides of the rectangular reciprocating slider 203, there are fixedly connected L-shaped frames 309. The limiting shell 307 drives the pressing seat 308 to slide horizontally on the outer wall of the L-shaped frame 309, and the L-shaped frame 309 drives the pressing seat 308 to slide vertically inside the limiting shell 307. The upper end of the pressing seat 308 extends above the connecting plate 103. On one side of the front outer wall and the other side of the back outer wall of the model storage box 110, there are fixedly connected vibration convex seats 313, and the vibration convex seats 313 are all located at the lower end of the outer wall of the model storage box 110. The vibration convex seats 313 are located on one side of the upper end of the adjusting convex plate 220. During the horizontal movement of the pressing seat 308, it cooperates with the vibration convex seats 313. On the upper surface of the L-shaped frame 309, there is opened a horizontal limiting groove 311. On the lower surface of the pressing seat 308, there is fixedly connected a horizontal limiting block 310, and the horizontal limiting block 310 is slidably connected inside the horizontal limiting groove 311. On the inner walls of both sides of the upper end of the limiting shell 307, there are fixedly connected vertical limiting blocks 312. On both sides of the lower end of the pressing seat 308, there are respectively opened vertical limiting grooves 315, and the vertical limiting blocks 312 are slidably connected inside the vertical limiting grooves 315. Specifically, during the rotation of the reciprocating short screw 202, the first bevel gear 301 meshes with the fourth bevel gear 314 and drives the third rotating rod 302 to rotate. At this time, under the meshing of the second bevel gear 303 and the third bevel gear 305, the reciprocating long screw 304 starts to rotate, causing the circular reciprocating slider 306 to perform a horizontal reciprocating linear motion on the reciprocating long screw 304. At this time, the circular reciprocating slider 306 will drive the limiting shell 307 to move synchronously. The pressing seat 308 in the limiting shell 307 realizes the compound motion of sliding horizontally on the outer wall of the L-shaped frame 309 and sliding vertically inside the limiting shell 307 through the sliding cooperation of the horizontal limiting block 310 and the horizontal limiting groove 311, and the sliding cooperation of the vertical limiting block 312 and the vertical limiting groove 315. Furthermore, when the vibration convex seat 313 moves upward, the pressing seat 308 will also move upward synchronously and move horizontally periodically. At this time, the pressing seat 308 will periodically press the vibration convex seat 313,Thus, the model storage box 110 generates a lateral vibration. At the same time, when the front pressing seat 308 presses the vibration convex seat 313, the pressing seat 308 at the rear end is located at the notch of the vibration convex seat 313, thereby ensuring the stability of the lateral vibration of the model storage box 110.

[0056] Such as Figure 15 and Figure 16The shown vibration position adjustment mechanism 4 includes a position adjustment frame 401. The position adjustment frame 401 is arranged on both sides of the upper surface of the connection plate 103. Transverse positioning grooves 409 are provided on both sides of the upper surface of the connection plate 103. One end of the lower surface of the position adjustment frame 401 far from the pressing seat 308 is fixedly connected with a transverse positioning block 407. The transverse positioning block 407 is slidably connected inside the transverse positioning groove 409. One end of the position adjustment frame 401 close to the pressing seat 308 is fixedly connected with a vertical positioning block 408. A vertical positioning groove 410 is provided at one end of the pressing seat 308 close to the position adjustment frame 401. The vertical positioning block 408 is slidably connected inside the vertical positioning groove 410. The outer wall of one side of the adjusting convex plate 220 is fixedly connected with a convex frame 402. A plurality of connecting springs 403 are fixedly connected to the lower surface of the convex frame 402. The lower surface of the connecting spring 403 is fixedly connected with an assembly circular plate 404. The upper surface of the assembly circular plate 404 is fixedly connected with an upper lifting frustum 405. The upper end of the upper lifting frustum 405 penetrates through the convex frame 402. The lower surface of the assembly circular plate 404 is fixedly connected with a lower lifting frustum 406. One end of the upper surface of the position adjustment frame 401 far from the pressing seat 308 cooperates with the lower lifting frustum 406. During the lateral movement of the pressing seat 308, it will drive the position adjustment frame 401 to move laterally. When the position adjustment frame 401 contacts the lower lifting frustum 406, it will squeeze the lower lifting frustum 406, and make the assembly circular plate 404 drive the upper lifting frustum 405 to move upward, so that a corner of the vibration plate 105 is lifted, and finally the vibration position of the vertical vibration mechanism 2 is changed, which is more in line with the uneven vibration situation in the actual earthquake. Among them, when the pressing seat 308 moves upward, the vertical positioning block 408 will slide inside the vertical positioning groove 410. At the same time, when the pressing seat 308 moves laterally, the transverse positioning block 407 will slide inside the transverse positioning groove 409, so that the position of the position adjustment frame 401 can only move back and forth laterally and cannot move up and down. At the same time, the position adjustment frame 401 is located at different positions on the connection plate 103. Therefore, when the rear position adjustment frame 401 squeezes the lower lifting frustum 406, the rear position adjustment frame 401 cannot squeeze the lower lifting frustum 406, and only a corner of the vibration plate 105 can be intermittently lifted, further simulating the influence of seismic motions at different positions on the gently inclined bedding rock slope model. Among them, a variety of vibrations of the model storage box 110 are realized by starting a servo motor 201. First, it can make the model storage box 110 generate vertical and lateral vibrations at the same time. The vertical vibration is generated by the cooperation of the cam 211 and the vibration plate 105, and the lateral vibration is generated by the cooperation of the pressing seat 308 and the vibration convex seat 313. Acting together with the vertical vibration, it truly restores the complex multi-dimensional vibration situation suffered by the slope during an earthquake. Second, the inclined state of the front end of the vibration plate 105 being high and the rear end being low and the uneven vibration distribution effectively simulate different stress conditions of the slope during an earthquake, with a larger vertical displacement and acceleration at the front end and a relatively smaller vertical movement at the rear end.It is in line with the difference in the impact of actual earthquake waves on different parts of the slope. Thirdly, during the vibration process, a corner of the vibration plate 105 can be intermittently lifted up by the upper lifting table 405, changing the vibration position and vibration effect of the vertical vibration mechanism 2, which is more in line with the uneven vibration in actual earthquakes. Fourthly, the model storage box 110 can produce vertical, horizontal and specific tilt vibrations. Through the coordination of multiple components, multi-dimensional vibrations are restored, force differences and uneven vibrations are simulated, which greatly improves the accuracy of the seismic simulation test of the gently inclined rock slope.

[0057] Specifically, the working principle of the seismic motion simulation test device for gently inclined bedding rock slopes is as follows: In the seismic motion simulation test of gently inclined bedding rock slopes, first, start the servo motor 201 to make the rectangular reciprocating slider 203 start to perform up-and-down reciprocating linear motion under the rotational drive of the reciprocating short screw 202. At the same time, the fixed plate 204 drives the installation box 205 to perform synchronous up-and-down reciprocating linear motion. At this time, the toothed cylinder 208 on the outer wall of the first rotating rod 207 meshes with the toothed plate 206. When the installation box 205 moves up and down, the toothed cylinder 208 rolls along the toothed plate 206 and drives the first rotating rod 207 to rotate. The first transmission wheels 212 on the front and rear outer walls of the first rotating rod 207 and the middle second rotating rod 210 achieve synchronous rotation through the first toothed belt 213. At the same time, the second transmission wheels 214 on the outer walls of the two side second rotating rods 210 also achieve synchronous rotation through the second toothed belt 215. When the second rotating rod 210 rotates, the cam 211 on its outer wall also rotates accordingly. During the rotation process, the cam 211 contacts the lower surface of the vibrating plate 105, thereby achieving the purpose of jacking up the vibrating plate 105 and causing the vibrating plate 105 to generate vertical vibration. At the same time, since the distance that the rectangular reciprocating slider 203 reciprocates on the outer wall of the reciprocating short screw 202 is relatively short, under the meshing of the toothed plate 206 and the toothed cylinder 208, the first rotating rod 207 rotates in a semi-circular reciprocating motion. At the same time, the second rotating rod 210 rotates synchronously with the first rotating rod 207. Therefore, the rotation period of the cam 211 is also half a cycle. After jacking up the vibrating plate 105, it will return to its original position under the action of the second rotating rod 210. At the same time, the vibrating plate 105 is connected to the connecting plate 103 through the reset thick spring 104. The reset thick spring 104 plays a role in resetting during the vibration process, enabling the vibrating plate 105 to vibrate continuously and stably. At the same time, when the rectangular reciprocating slider 203 moves upward, it will also drive the one-way lead screw 221 to rotate. At this time, the front one-way slider 222 will drive the fixed frame 223 and the pressing plate 225 to move inside the chute 224 and jack up the adjusting convex plate 220. At the same time, the rear one-way slider 222 will drive the fixed frame 223 and the pressing plate 225 to leave the inside of the chute 224, and the adjusting convex plate 220 will return to its original position under the action of the short reset spring 219. At this time, the whole vibrating plate 105 is at an angle with the front end higher and the rear end lower. At this time, the relatively higher position at the front end of the vibrating plate 105 will obtain a larger vertical displacement and acceleration compared to the rear end under the jacking action of the cam 211, while the relatively lower position at the rear end will experience a relatively smaller vertical movement, thus forming a non-uniform vibration distribution, further simulating the differences in the vibration wave effects on different parts of the slope during an earthquake, further promoting more realistic deformation and dislocation of the bedding rock structure. At the same time, during the rotation of the reciprocating short screw 202, the first bevel gear 301 meshes with the fourth bevel gear 314 and drives the third rotating rod 302 to rotate. At this time, under the meshing of the second bevel gear 303 and the third bevel gear 305, the reciprocating long screw 304 starts to rotate.The circular reciprocating slider 306 is made to perform a lateral reciprocating linear motion on the reciprocating long screw 304. At this time, the circular reciprocating slider 306 will drive the limit shell 307 to move synchronously. The pressing seat 308 inside the limit shell 307 is in sliding fit with the lateral limit groove 311 through the lateral limit block 310, and in sliding fit with the vertical limit groove 315 through the vertical limit block 312, realizing a compound motion of lateral sliding on the outer wall of the L-shaped frame 309 and vertical sliding inside the limit shell 307. Furthermore, when the vibration convex block 313 moves upward, the pressing seat 308 will also move upward synchronously and laterally periodically. At this time, the pressing seat 308 will periodically squeeze the vibration convex block 313, thereby causing the model storage box 110 to generate lateral vibration. At the same time, when the front pressing seat 308 squeezes the vibration convex block 313, the pressing seat 308 at the rear is located at the notch of the vibration convex block 313, thus ensuring the stability of the lateral vibration of the model storage box 110. At the same time, during the lateral movement of the pressing seat 308, it will drive the position adjustment frame 401 to move laterally. When the position adjustment frame 401 contacts the lower lifting frustum 406, it will squeeze the lower lifting frustum 406, and cause the assembly circular plate 404 to drive the upper lifting frustum 405 to move upward, lifting a corner of the vibration plate 105, and finally changing the vibration position of the vertical vibration mechanism 2, making it more in line with the uneven vibration situation in actual earthquakes. Among them, when the pressing seat 308 moves upward, the vertical positioning block 408 will slide inside the vertical positioning groove 410. At the same time, when the pressing seat 308 moves laterally, the horizontal positioning block 407 will slide inside the horizontal positioning groove 409, so that the position of the position adjustment frame 401 can only move laterally reciprocally and cannot move up and down. At the same time, the position adjustment frame 401 is located at different positions of the connecting plate 103. Therefore, when the rear position adjustment frame 401 squeezes the lower lifting frustum 406, the rear position adjustment frame 401 cannot squeeze the lower lifting frustum 406, and can only intermittently lift a corner of the vibration plate 105, further simulating the influence of ground motions at different positions on the gently inclined bedding rock slope model.
