摘　　要：滑坡、崩塌、泥石流、地塌、地陷等危害人民生命和财产安全的地质灾害发生前和发生时会出现地下深部的位移现象,尾矿坝在不断堆积中也会出现深部位移现象。因此,对岩土地下深部变形或位移进行监测是防御灾害、保障建筑和水利等岩土工程质量的必要的手段。现有的测斜测量仪必须由人工操作测量,且测量准确性与操作者的技术有关;还有,当测斜管发生大曲率弯曲时,测量探头无法放下去完成测量。另外,测斜管具有较好的抗破坏强度,当地下土质较软时,实际地下土体的位移大于测斜管的倾斜角度所对应的位移值。提出基于测斜和霍尔效应的地下变形(位移)测量集成传感器单元的构成,组成相应的地下位移测量仪器系统,以及地下变形(位移)测量方法,以便解决现有测斜测量仪的缺点。It usually appears the phenomenon of deep underground displacement when geological disasters such as landslide,collapse,debris flow,subsidence and other harmful to people＇s life and property safety occur. Tailings dam in the continuous accumulation also appears deep displacement phenomenon. Therefore,monitoring the deformation and displacement of the rock is a necessary means of protecting the quality of rock and soil engineering including defense,construction and water conservancy. The existing measuring instrument must be measured by manual operation,and the accuracy of measurement is related to the operator＇s technique. Also,when the test tube occurred in large curvature,the measuring probe cannot be put down to finish the measurement. In addition,it has good anti-failure strength. When the underground soil is soft,the displacement of the actual underground soil is larger than that of the inclined tube. In this paper,the structure of the integrated sensor unit,which is based on the measurement of the inclination and the Holzer effect,is proposed to measure the integrated sensor unit.
