Multi-layer sliding zone landslide and slide-resistant pile model test system and method
The invention provides a multi-layer sliding zone landslide and slide-resistant pile model test system. The system comprises a model box, a landslide monitoring device and a movable loading device. The model box is internally provided with a simulated slide bed, a simulated landslide body and a simulated slide-resistant pile. The simulated landslide body is internally provided with multiple layersof simulated sliding zones. The simulated slide-resistant pile is buried in the simulated landslide body. The landslide monitoring device comprises micro resistor type strain gages, micro resistor type earth pressure cells, flexible inclinometers and a 3D laser scanner which are arranged in the simulated landslide body. The movable loading device comprises a lifting rod, hydraulic jacks and a stretchable bearing plate. The rear ends of the hydraulic jacks are movably connected with the lifting rod, and the front ends of the hydraulic jacks are movably connected with the stretchable bearing plate. The front end face of the stretchable bearing plate is attached to the rear end face of the simulated landslide body. The multi-layer sliding zone landslide and slide-resistant pile model test system has the beneficial effects that the adjustable vertical height of the stretchable bearing plate is consistent with the thickness of the corresponding borne single-layer landslide body, the layering thickness of the landslide body can be changed at will for load applying, and accurate simulation is realized.
本发明提供一种多层滑带滑坡‑抗滑桩模型试验系统，包括模型箱、滑坡监测装置和活动加载装置；模型箱内设有模拟滑床、模拟滑坡体和模拟抗滑桩，模拟滑坡体内设有多层模拟滑带，模拟抗滑桩埋设于模拟滑坡体内；滑坡监测装置包括设置于模拟滑坡体内的微型电阻式应变片、微型电阻式土压力盒和柔性测斜仪、以及三维激光扫描仪；活动加载装置包括升降杆、液压千斤顶和可伸缩承载板，液压千斤顶后端活动连接升降杆、前端活动连接可伸缩承载板，可伸缩承载板的前端面与模拟滑坡体的后端面贴合。本发明的有益效果：可伸缩承载板可调整竖直方向的高度与对应受载的单层滑坡体厚度一致，可任意改变滑坡体的分层厚度进行施加荷载，实现精准模拟。
