摘　　要：通过对裂隙岩体露头处的裂隙进行调查统计,根据各结构面的分布特征,进行计算机裂隙网络模拟.利用数值计算方法求解等效岩体渗透张量,通过对服从某分布的裂隙网络进行多次抽样,得到该分区岩体渗透性的系列等效值,进而可以评价研究区岩体的渗透性状况,同时为合理评价工程岩体的稳定性提供科学依据.图3,参7.Investigation about fractures on the exposure of the fractured rock mass is performed ordinarily, to evaluate the mechanics property of rock mass. Fracture network is simulated by the aid of computer on the base of the distribution property of structrual planes. The fractured network is equivalent to the continuum by the numerical methods. By many samplings, series of value K can be obtained. As the result, we can assess the fractured rock mass permeability, and provide reliable information for evaluating the stability of engineering rock mass.3figs.,7refs.
