此处所进行的研究,是为了对於水平层叠的粘土岩层为地基的水工建筑物‘平面’滑动的稳定性加以核算。考虑到土壤的特性,在研究其抗剪强度的时候,不能仅限於一般化的试验,而是应该(按照所确定的接触剪切力)作一些特别的试验,测定接触面上的剪切力。这样的试验是用水力发电设计总局莫斯科分局的MVC-46型仪器进行的,试样的面积为40CM~2。把普通完整的试样,以及地层分界间的天然接触面,混凝土与地层间的人工接触面,砂土岩与粘土岩间的分界面均加以试验,后者是在某种程度上土层形成破裂面区域剪切的模型,其抗剪强度的总值中,不包括结构凝聚力。用整块样品试验后的结果表明,一些地层
The research carried out here is intended to account for the ’planar’ sliding stability of hydraulic structures where the horizontal layers of clay rock are groundwork. Considering the characteristics of the soil, when studying its shear strength, it should not be limited to generalized tests. Instead, special tests should be carried out (according to the determined contact shear force) to determine the shear force at the contact surface . Such tests are carried out using the MVC-46 instrument from the Moscow branch of the Design Bureau of Hydroelectric Power, with an area of 40 cm -2. The normal intact specimen, as well as the natural contact surface between the stratigraphic boundaries, the artificial contact surface between the concrete and the formation, the interface between the sandstone and the clay rock, is tested, to a certain extent, The model of shear zone is formed, whose total shear strength does not include the structural cohesion. The results of the whole sample test show that some of the formations
