Description

Technical Field

[0001] The present application relates to the technical field of rock and soil earthquake experiments, and in particular to a seismic motion simulation test device for a gently inclined, layered rock slope. Background Art

[0002] Gently inclined bedding rock slopes are widely found in mountainous areas, hilly areas and other terrain areas. With the continuous advancement of infrastructure construction, a large number of engineering activities involve such slopes. However, seismic activity poses a serious threat to the stability of gently inclined bedding rock slopes. When an earthquake occurs, the seismic waves generated will cause the vibration of the slope rock and soil, resulting in changes in the internal stress state of the rock and soil, which may in turn cause slope instability, resulting in geological disasters such as landslides and collapses, causing great damage to surrounding buildings, transportation facilities and human life safety. For example, in the construction of some mountain roads, if the stability of gently inclined bedding rock slopes under the action of earthquakes is not fully considered, once an earthquake occurs, the instability of the slope may block traffic, causing serious economic losses and casualties. For this reason, the seismic motion simulation test of gently inclined bedding rock slopes is particularly important.

[0003] However, during the use of existing seismic motion simulation test devices for gently inclined bedding rock slopes, most of them can only vibrate the model storage box in one direction or two directions. However, in actual earthquakes, the slope is subjected to complex multi-dimensional vibrations, including a combination of vertical, lateral and longitudinal vibrations. Vibration simulation in only one direction or two directions cannot truly restore the complexity of seismic motion, and ignores the coupling effect between vibrations in different directions, which in turn affects the accuracy of the experiment and is not conducive to accurately evaluating the stability of the slope.

The servo motor 201 is fixedly connected to the middle part of the upper surface of the bottom plate 101. The output end of the servo motor 201 is fixedly connected to a reciprocating short screw 202. The rod body of the reciprocating short screw 202 is sleeved with a rectangular reciprocating slider 203. The outer walls of the front and rear ends of the rectangular reciprocating slider 203 are fixedly connected to a fixing plate 204. The end of the upper surface of the fixing plate 204 close to the rectangular reciprocating slider 203 is fixedly connected to a mounting box 205. The front and rear ends of the lower surface of the connecting plate 103 are fixedly connected to a tooth plate 206. The lower end of the inner wall of the mounting box 205 is rotatably connected to a first rotating rod 207. The outer walls of the front and rear ends of the first rotating rod 207 are fixedly connected to a gear cylinder 208. 208 is meshed with the tooth plate 206, the upper ends of the installation box 205 extend to the upper part of the connecting plate 103 and are fixedly connected with a vibration box 209, the inner wall of the vibration box 209 is rotatably connected with a second rotating rod 210, the outer wall of the second rotating rod 210 is fixedly connected with a cam 211, and the cam 211 contacts the lower surface of the vibration plate 105 during rotation, the outer walls of the front and rear ends of the first rotating rod 207 and the middle second rotating rod 210 are fixedly connected with a first transmission wheel 212, the outer wall of the first transmission wheel 212 is provided with a first toothed belt 213, the outer walls of the second rotating rods 210 on both sides are respectively fixedly connected with second transmission wheels 214, the outer wall of the second transmission wheel 214 is provided with a second toothed belt 215, and the upper surface of the fixed plate 204 is away from the rectangular reciprocating slide One end of the block 203 is fixedly connected with a transfer block 216, the upper end of the transfer block 216 passes through the connecting plate 103 and is fixedly connected to the middle of the lower surface of the adjusting box 217, an adjusting groove 218 is provided on the upper surface of the adjusting box 217 away from the vibration box 209, and short return springs 219 are fixedly connected to the two sides of the bottom of the adjusting groove 218, and the upper ends of the short return springs 219 are fixedly connected to the adjusting convex plate 220, and the end of the first rotating rod 207 away from the rectangular reciprocating slider 203 passes through the mounting box 205 and is fixedly connected with a one-way screw rod 221, the outer wall of the one-way screw rod 221 is sleeved with a one-way slider 222, and the outer wall of one side of the one-way slider 222 is fixedly connected with a fixing frame 223, and the upper end of the fixing frame 223 extends to the connecting plate 103. 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, the servo motor 201 is started to make the rectangular reciprocating slider 203 start to do up and down reciprocating linear motion under the rotation drive of the reciprocating short screw 202, and at the same time, the fixed plate 204 drives the installation box 205 to also do up and down reciprocating linear motion synchronously. At this time, the gear cylinder 208 on the outer wall of the first rotating rod 207 is meshed with the tooth plate 206, so that when the installation box 205 moves up and down, the gear cylinder 208 rolls along the tooth plate 206 and drives the first rotating rod 207 to rotate. The first rotating rod 207 and the first transmission wheel 212 on the outer wall of the front and rear ends of the middle second rotating rod 210 realize synchronous rotation through the first toothed belt 213. At the same time, the second rotating rods 210 on both sides rotate synchronously. The second transmission wheel 214 on the outer wall of the body also realizes 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. The cam 211 contacts the lower surface of the vibration plate 105 during the rotation process, thereby achieving the purpose of lifting the vibration plate 105, so that the vibration plate 105 produces 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 short, the tooth plate 206 and the gear cylinder 208 are meshed with each other, and the first rotating rod 207 reciprocates in a half-circle. At the same time, the second rotating rod 210 rotates synchronously with the first rotating rod 207, so that the cam 211 The rotation cycle is also half a cycle. After the vibration plate 105 is lifted, it will return to its original position under the action of the second rotating rod 210. At the same time, the vibration plate 105 is connected to the connecting plate 103 through the reset thick spring 104. The reset thick spring 104 plays a reset role during the vibration process, so that the vibration plate 105 can vibrate continuously and stably. At the same time, the one-way screw rod 221 will be driven to rotate during the upward movement of the rectangular reciprocating slider 203. At this time, the one-way slider 222 at the front end will drive the fixing frame 223 and the extrusion plate 225 to move inside the slide groove 224 and lift the adjusting convex plate 220 upward. At the same time, the one-way slider 222 at the rear end will The fixing frame 223 and the extrusion plate 225 are driven to leave the interior of the slide groove 224, and the adjusting convex plate 220 is returned to its original position under the action of the short return spring 219. At this time, the vibration plate 105 is at an angle with the front end higher and the rear end lower. At this time, the higher position of the front end of the vibration plate 105 will obtain a larger vertical displacement and acceleration than the rear end under the lifting action of the cam 211, while the relatively lower position of the rear end will experience a relatively small vertical movement, thereby forming an uneven vibration distribution, thereby simulating the difference in the impact of vibration waves on different parts of the slope during an earthquake, and further promoting more realistic deformation and dislocation of the bedding rock structure.

Vertical limiting grooves 315 are respectively provided on both sides of the lower end of the pressing seat 308. The vertical limiting block 312 is slidably connected inside the vertical limiting groove 315. Specifically, during the rotation of the reciprocating short screw 202, the first bevel gear 301 and the fourth bevel gear 314 mesh with each other and drive the third rotating rod 302 to rotate. At this time, The second bevel gear 303 and the third bevel gear 305 mesh with each other and the reciprocating long screw 304 starts to rotate, causing the circular reciprocating slider 306 to perform horizontal 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 in the limit shell 307 slides with the horizontal limit groove 311 through the horizontal limit block 310, and the vertical limit block 312 slides with the vertical limit groove 315, thereby realizing a composite motion of sliding horizontally on the outer wall of the L-shaped frame 309 and sliding vertically inside the limit shell 307. As a result, during the upward movement of the vibration convex seat 313, the pressing seat 308 will also move upward synchronously and move horizontally periodically.

At the same time, when the front pressing seat 308 squeezes the vibration convex seat 313, the rear pressing seat 308 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.

[0035] like Fig.15 and Fig.16The vibration position adjustment mechanism 4 includes a position adjustment frame 401, which is arranged on both sides of the upper surface of the connecting plate 103. Both sides of the upper surface of the connecting plate 103 are provided with transverse positioning grooves 409. The end of the lower surface of the position adjustment frame 401 away from the pressing seat 308 is fixedly connected with a transverse positioning block 407, and the transverse positioning block 407 is slidably connected inside the transverse positioning groove 409. The end of the position adjustment frame 401 close to the pressing seat 308 is fixedly connected with a vertical positioning block 408. The end of the pressing seat 308 close to the position adjustment frame 401 is provided with a vertical positioning groove 410. The vertical positioning block 408 slides 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. The convex frame 40 2 is fixedly connected with a plurality of connecting springs 403, 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 platform 405, the upper end of the upper lifting platform 405 passes through the convex frame 402, the lower surface of the assembly circular plate 404 is fixedly connected with a lower lifting platform 406, the end of the upper surface of the position adjustment frame 401 away from the pressing seat 308 cooperates with the lower lifting platform 406, during the lateral movement of the pressing seat 308, the position adjustment frame 401 will be driven to move lateral, when the position adjustment frame 401 contacts the lower lifting platform 406, the lower lifting platform 406 will be squeezed, and the assembly circular plate 404 will drive the upper lifting platform 405 to move upward, so that the vibration plate One corner of 105 is lifted up, 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. 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 horizontally, 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 back and forth horizontally, 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, and when the rear end position adjustment frame 401 squeezes the lower lifting table 406, the rear end position adjustment frame 401 cannot squeeze the lower lifting table 406, and can only make one corner of the vibration plate 105 be lifted up. The model storage box 110 is lifted and stopped to further simulate the influence of earthquake motions at different positions on the gently inclined rock slope model. Among them, a servo motor 201 is started to realize multiple vibrations of the model storage box 110. First, the model storage box 110 can 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. Together with the vertical vibration, the complex multi-dimensional vibration of the slope during an earthquake is truly restored. Secondly, the tilted state of the vibration plate 105 with a high front end and a low rear end and the uneven vibration distribution effectively simulate the different stress conditions of the slope during an earthquake, with a larger vertical displacement and acceleration at the front end and a relatively small 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.

[0036] Specifically, the working principle of the seismic simulation test device for a gently inclined and layered rock slope is as follows: in the seismic simulation test for a gently inclined and layered rock slope, the servo motor 201 is first started to make the rectangular reciprocating slider 203 start to do up and down reciprocating linear motion under the rotation drive of the reciprocating short screw 202, and at the same time, the fixed plate 204 drives the installation box 205 to also do synchronous up and down reciprocating linear motion. At this time, the gear cylinder 208 on the outer wall of the first rotating rod 207 is meshed with the tooth plate 206, so that when the installation box 205 moves up and down, the gear cylinder 208 rolls along the tooth plate 206 and drives the first rotating rod 207 to rotate. The first transmission wheel 212 on the outer wall of the front and rear ends of the first rotating rod 207 and the middle second rotating rod 210 is realized through the first toothed belt 213 The second rotating rod 210 rotates synchronously, and the second transmission wheel 214 on the outer wall of the rod body of the second rotating rod 210 on both sides also rotates synchronously through the second toothed belt 215. When the second rotating rod 210 rotates, the cam 211 on its outer wall also rotates accordingly. The cam 211 contacts the lower surface of the vibration plate 105 during the rotation process, thereby achieving the purpose of lifting the vibration plate 105, causing the vibration plate 105 to vibrate vertically. 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 short, and then under the mutual meshing of the tooth plate 206 and the gear cylinder 208, the first rotating rod 207 reciprocates in half a circle, and the second rotating rod 210 rotates synchronously with the first rotating rod 207, and then the rotation period of the cam 211 is also half a circle. When the vibration plate 105 is lifted, 05, it will return to its original position under the action of the second rotating rod 210, and at the same time, the vibration plate 105 is connected to the connecting plate 103 through the thick reset spring 104. The thick reset spring 104 plays a reset role during the vibration process, so that the vibration plate 105 can vibrate continuously and stably. At the same time, the one-way screw rod 221 will be driven to rotate during the upward movement of the rectangular reciprocating slider 203. At this time, the one-way slider 222 at the front end will drive the fixing frame 223 and the extrusion plate 225 to move inside the slide groove 224 and push up the adjusting convex plate 220. At the same time, the one-way slider 222 at the rear end will drive the fixing frame 223 and the extrusion plate 225 to leave the inside of the slide groove 224, and make the adjusting convex plate 220 return to its original position under the action of the short reset spring 219. At this time, the vibration plate 105 as a whole is at an angle of high front end and low rear end. At this time, the higher position of the front end of the vibration plate 105 will obtain a larger vertical displacement and acceleration than the rear end under the lifting action of the cam 211, while the relatively lower position of the rear end will experience a relatively small vertical movement, thereby forming an uneven vibration distribution, thereby simulating the difference in the impact of vibration waves on different parts of the slope during an earthquake, and 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 and the fourth bevel gear 314 are meshed with each other and drive the third rotating rod 302 to rotate. At this time, the reciprocating long screw 304 starts to rotate under the meshing of the second bevel gear 303 and the third bevel gear 305.The circular reciprocating slider 306 makes a horizontal 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 in the limit shell 307 slides with the horizontal limit block 310 and the horizontal limit groove 311, and the vertical limit block 312 slides with the vertical limit groove 315, realizing a composite motion of sliding horizontally on the outer wall of the L-shaped frame 309 and sliding vertically inside the limit shell 307, thereby making the vibration convex seat 313 move upward. During the process, the pressing seat 308 will also move up synchronously and move laterally periodically. At this time, the pressing seat 308 will periodically squeeze the vibration convex seat 313, so that the model storage box 110 will vibrate laterally. At the same time, when the front pressing seat 308 squeezes the vibration convex seat 313, the rear pressing seat 308 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. 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 frame 401 contacts the lower lifting table 406, the lower lifting table 406 will be squeezed, and the assembly circular plate 404 will drive the upper lifting table 405 to move upward, so that a corner of the vibration plate 105 is lifted up, 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. When the pressing seat 308 moves upward, the vertical positioning block 408 will slide inside the vertical positioning groove 410, and when the pressing seat 308 moves horizontally, the horizontal positioning block 407 It will slide inside the transverse positioning groove 409, so that the position adjustment frame 401 can only move back and forth horizontally, but not up and down. At the same time, the position adjustment frame 401 is located at different positions of the connecting plate 103. When the rear position adjustment frame 401 squeezes the lower lifting table 406, the rear position adjustment frame 401 cannot squeeze the lower lifting table 406, and can only make a corner of the vibration plate 105 be intermittently lifted, further simulating the influence of earthquake motions at different positions on the gently inclined rock slope model.
