摘要
在一些滑坡治理工程中，为了更真实地研究滑坡内部滑体、滑带和滑床的岩土组成与结构特征，需要在不扰动滑坡结构稳定性的前提下采集土样并进行现场大剪切试验和变形监测。而目前的治理工程中，主要采用的是2×3m2矩形探井。本论文将详细讲解其开挖和支护方法。
Abstract
In some engineering landslide, to truly observe the rock and soil composition and structure characteristics of the landslide, sliding zone, sliding bed, and to sample the undisturbed soil and make large shear test and deformation monitoring on site, so as to make the digging well method has been applied to. At present, the main wells is 2 × 3 m2 rectangular wells. This theory study the rectangular wells’ excavation and supporting.
