摘要： 在围护结构施工过程中，监测结构深层、内部的变形，及时预报结构失稳的部位，对围护结构稳定性预测尤为重要。通过某地下车库围护结构(基坑)监测表明，采用钻孔侧向位移监测，可以揭示围护结构内部岩土变形状况，从而达到对围护结构稳定性进行预测的目的。

Abstract: Conventional ground deformation monitoring is to survey surface displacements. In supporting structure installations for deep excavations, it is especially more important to monitor the deformation inside the soil mass so that the potential structure instability can be forecasted by evaluation of internal deformation at various locations. This paper presents the results of stability evaluations of supporting structures for the deep excavation of an underground parking garage using lateral soil displacements measured by inclinometers.
