摘要
引用非饱和土抗剪强度理论研究了土体与玻璃间摩擦机理,为解决滑坡模型试验中模型槽侧壁玻璃与土体间摩擦边过大问题提供了试验依据,设计改造了室内土体直接剪切试验,证明了土体与模型槽侧壁玻璃接触面间存在吸力,且随土体含水量而变化,先增后减。
In this paper, the theory of shear strength in the non-saturated soil is used to study the frictional mechanism between soil and glass. Provided the test basis for solving the problem that the friction between soil and glass was too much in the landslide model test,and the direct shear test of soil is designed and modified to prove that the suction existed between soil and glass. The test shows that the size of suction changes with soil moisture and in the case of moisture increasing,the suction increases at first and then decreases.
