摘　　要：本文主要是以万州区近水平地层滑坡的滑带土为研究对象从影响滑带土抗剪强度参数的因素出发设计出切实可行的试验,全面系统地研究了粘粒含量、含水量和应力状态与抗剪强度参数的关系并对其机理进行详细的解释。可为万州区近水平地层滑坡以及具有膨胀性滑带土滑坡的稳定性评价和设计治理工程提供可靠的力学参数。In order to find out the changing rules of shear strength parameters for the expansive soil on the landslide slip surface in Wanzhou of Three Gorges Reservoir Area, the characteristic tests for the sliding soils have been carried out based on the factors to influence the parameters. The relationship between the clay content, water content, stress state and shear strength parameters are studied and the mechanism is deeply explained, which have provided the credible mechanics parameters for the stability evaluation and the controlling design of the landslide with expansive soil in the horizontal strata.
