| 摘 要： | 节理岩体强度与力学参数可通过最新版的广义Hoek-Brown破坏准则进行估计,其预测结果能够满足工程应用。建立在现场工程岩体详细工程地质勘察基础上的Q系统法,不仅为确定岩体GSI指标提供了便利,也可用于详细设计阶段的支护设计。通过工程应用说明了采用Hoek-Brown破坏准则预测节理岩体力学参数的过程。

| Abstract: | The strength and mechanical parameters of jointed rock mass can be estimated in terms of the lately generalized Hoek-Brown failure criterion,the estimated results can be applicable in project properly.Q system based on careful geology observations of in situ rock mass provides convenience to determine rock mass index GSI.Furthermore,it can be applied in detailed support design.An engineering calculation process shows how the mechanical parameters of jointed rock mass are estimated by means of Hoek-Brown failure criterion. |
