摘　　要：在岩土工程界,如何准确确定岩体的力学参数已成为一个迫在眉睫而又难以解决的问题。简略的介绍了几种当前在实际工程中运用较多的岩体强度参数经验确定方法,指出了它们所存在的不足之处。在此基础上,提出了一种综合考虑实验室标准岩石试件强度参数和岩体实地地质条件,以及外界扰动等因素的岩体强度参数经验确定方法;并通过一个具体的工程实例,初步证明该方法是可行的。How to accurately determine the mechanical parameters of rock mass has become an urgent and difficult problem to solve in geotechnical engineering.Some empirical methods in practical engineering rock mass strength parameters determined,and the exist inadequacies is briefly described.On this basis,a new rock mass strength parameter determination method has been put forward which comprehensive consideration of the laboratory standard rock specimen strength parameters and geological conditions and external disturbance.And through a specific project example,it is proved that the method is reasonable.
