Anchor rod stress monitoring and reconstructed slope stability evaluation method for anchoring type slope
The invention provides an anchor rod stress monitoring and reconstructed slope stability evaluation method for an anchoring type slope. The anchor rod stress monitoring and reconstructed slope stability evaluation method for the anchoring type slope comprises the steps that the stability of an original slope is analyzed by means of numerical simulation software, the cut-off stress is tested when an anti-slide pile encounters anchor rods at different depths, then the anchor rods exposed out of the pile are dismantled, residual anchor rods in a slope body are reserved, and afterwards, stress gauges are mounted on the residual anchor rods on the two sides of the pile for long-term monitoring; and finally, the stability under different working conditions is analyzed by means of the numerical simulation software, and the stability of a reconstructed slope is evaluated according to monitoring data. By the adoption of the anchor rod stress monitoring and reconstructed slope stability evaluation method for the anchoring type slope, detection of the cut-off stress of original anchor rods is realized during expanding construction of the anchoring type slope, the stress of the residual anchorrods is monitored in the whole construction process and for a long time after construction, the utilization of existing supporting structures and the evaluation of the stability of the reconstructedslope are studied based on data, stability analysis by means of the simulation software is comprehensively considered, and thus, results have higher research value.
本发明提供了一种锚固型边坡的锚杆应力监测及重建边坡稳定性评价方法，首先利用数值模拟软件进行原边坡稳定性分析，然后在抗滑桩不同深度遭遇既有锚杆时，测试截断应力，接着拆除桩内裸露锚杆后，保留坡体内残余锚杆，之后对桩内两侧残余锚杆进行应力计安装，以进行长期监测；最终利用数值模拟软件进行各工况稳定性分析，结合监测数据，进行重建边坡稳定性评价。本发明实现了锚固型边坡在扩建施工时对原有锚杆截断应力的检测，对残余锚杆应力在施工全过程以及施工后长期的监测，利用数据展开对既有支挡结构的利用以及重建后边坡的稳定性进行评价的研究，还综合考虑利用模拟软件进行稳定性分析，结果更具研究价值。
