摘要
在某大型水利水电工程建设的原位监测工作中,发生锚杆应力计应力超量程问题。是否由裂隙的滑移剪切造成的,在室内进行了大型锚杆剪切模型试验,模拟锚杆在滑移剪切荷载作用下的工作性状。在试验中采用了多种类型的应力和应变传感器,并进行了优化组合,为整个试验数据的成功获得奠定了基础。
The bolt stress gauge outrange problems often happened in in-situ monitoring work in domestic large-scale water conservancy and hydropower project construction.Whether caused by the slip shear fractures or not,indoor large bolt shear model test is carried out to simulate anchor work characteristics under shear load.Multiple types of stress and strain sensors are used in the test,and the optimized combination set up the basis for successful acquisition of the whole test data.
