Transparent soil slope anchor rod dynamic response testing device and slope sliding surface identification method
The invention discloses a transparent soil slope anchor rod dynamic response testing device and a slope sliding surface recognition method. The testing device comprises a model box, a loading assembly and a monitoring assembly. A transparent soil side slope is formed in the model box through layered stacking and pressing, and an anchor rod is hit into the transparent soil side slope; the monitoring assembly comprises an OFDR optical fiber data acquisition instrument, an OFDR optical fiber data processing and analyzing platform, a fixing clamp, optical fiber sensors arranged on the anchor rod and optical fiber sensors buried in the transparent soil slope in a layered mode. An optical fiber winding disc is arranged at the end of the anchor rod, and a tail winding column is arranged at the tail of the anchor rod. An anchor rod provided with an optical fiber sensor is driven into the transparent soil slope, the optical fiber sensor laid on the anchor rod is connected to an OFDR optical fiber data acquisition instrument, and in each stage of loading, the position point of the slope sliding surface is determined according to the strain peak value of the anchor rod monitored by the optical fiber sensor and the strain peak value of a slope soil body. The survival rate of the optical fiber sensor in the anchor rod construction process is improved, and high-precision monitoring of the strain of the side slope anchor rod is achieved.
本发明公开了一种透明土边坡锚杆动态响应测试装置及边坡滑动面识别方法，该测试装置包括模型箱、加载组件和监测组件；模型箱内分层堆压形成透明土边坡，透明土边坡内打入有锚杆；监测组件包括OFDR光纤数据采集仪、OFDR光纤数据处理与分析平台、固定夹具、布设在锚杆上的光纤传感器和分层埋设在透明土边坡内的光纤传感器；锚杆端部设有光纤缠线盘，锚杆尾部设有尾部缠线柱。本发明将布设有光纤传感器的锚杆打入透明土边坡内，将铺设在锚杆上的光纤传感器连接至OFDR光纤数据采集仪，在每级加载中，根据光纤传感器监测到的锚杆的应变峰值及边坡土体的应变峰值确定边坡滑面的位置点。本发明提高了光纤传感器在锚杆施工过程的存活率，实现了边坡锚杆应变的高精度监测。
