摘　　要：粘聚力c和内摩擦角φ是岩土体的两个非常重要的参数,在工程设计中得到了广泛的应用。c,φ分别代表着岩土体的摩擦强度和粘结强度,虽然这两个参数是由试验得出的曲线人为定义的,但土的粘结强度和摩擦强度是真实存在的,因而这两个参数具有其实际意义。从c,φ的含义、确定方法、影响因素和两者之间的联系对土体的粘聚力和内摩擦角进行了讨论。Cohesion c and internal friction angleφis two very important parameter of cohesive clay,have been widely used in engineering designing.The value of c andφrepresents the frictional strength and bond strength of rock and soil,although these two parameters is defined by the test curve artificially,bond strength and friction strength is exactly exists in soil,thus these two parameters has its practical significance.This paper discuss the cohesion and internal friction angle from its implication,determination,influence factors and the connection between them.

关 键 词：粘聚力c 内摩擦角φ 剪切试验
