摘要
岩体抗剪强度是大坝设计最基本的参数,一般通过室内及现场试验取得的c, f值再经地质折减获取。研究表明,由于地质折减要考虑的因素很多且关系复杂,设计采用值的取得是一件相当艰难的事。除了岩性与岩体结构以外,岩体的围压条件也是影响取值的因素之一。
The rockmass shear strength is a fundamental parameter for dam design, and is normally obtained through the field or laboratory test with geological discount. The research result shows that it is very difficult to obtain the design value of rockmass shear strength because a lot of factors are necessary to be considered. In addition to the rock composition and structure, the stress state of rockmass is also a factor to influence the rockmass shear strength.
