摘　　要：本文以瑶寨隧道为研究对象,结合现场地质分析与结构面统计,以Monte-Carlo法为基础,对该隧道各测线不同等级围岩分别进行结构面网络模拟,评价遂道岩体的结构性质,并进行工程岩体分类,估算其力学参数,以为采取合适的围岩支护方式提供依据。According to geological analysis and statistics of structural planes,this paper selected Yaozhai tunnel as the research object.The discontinuity network simulations were made separately for different grades of surrounding rock of the tunnel based on Monte-Carlo method so as to evaluate the structural texture of rock mass,classify the engineering rock mass and calculate the mechanical parameters to provide the basis for taking the appropriate way of surrounding rock supports.

关 键 词：岩体结构面 网络模拟 岩体结构性质 MONTE-CARLO法 瑶寨隧道
