Servo steel support foundation pit model test device
A servo steel support foundation pit model test device comprises a model box, an enclosure structure baffle is vertically inserted into the model box, strain gauges are symmetrically arranged on the soil facing face and the soil backing face of the enclosure structure baffle, and meanwhile a miniature soil pressure box is arranged on the soil facing face of the enclosure structure baffle. The strain gauges and the miniature soil pressure boxes are electrically connected with an external reading device, a plurality of model supports are further arranged between the retaining structure baffle and the inner side wall of the model box, the model supports are connected with the model box through support adjusting ends, and the support adjusting ends are electrically connected with an external axial force servo control terminal through wires. According to a specific test scheme, the application positions and the number of the common model supports and the servo model supports can be flexibly adjusted in the sliding grooves in the side wall of the model box, and the supporting axial force and deformation are adjusted through the axial force servo control terminal and the supporting adjusting end; and the strain gauges and the miniature soil pressure boxes are adopted to synchronously monitor the deformation of the enclosure structure, the deformation of the supporting members and the change conditions of the soil pressure behind the wall.
一种伺服钢支撑基坑模型试验装置，包括模型箱，模型箱的内部竖向插接有围护结构挡板，围护结构挡板的迎土面和背土面对称设置应变片，同时在围护结构挡板的迎土面设置微型土压力盒，应变片和微型土压力盒与外部的读数装置电性连接，围护结构挡板与模型箱内侧壁之间还设置有若干块模型支撑，模型支撑与模型箱之间通过支撑调整端头连接，支撑调整端头通过电线与外部的轴力伺服控制终端电性连接，本发明可以根据具体试验方案在模型箱侧壁滑槽中灵活调整普通模型支撑和伺服模型支撑的施作位置和数量，通过轴力伺服控制终端及支撑调整端头调整支撑轴力和变形，并采用应变片和微型土压力盒同步监测围护结构变形、支撑构件变形和墙后土压力的变化情况。
