| 摘 要： | Hoek-Brown强度准则与Mohr-Coulomb强度准则相比,综合考虑了岩体结构、岩块强度、应力状态等多种因素的影响,可更好地反映岩体的非线性破坏特征,更符合工程实际,由该准则所估算的岩体力学参数可为最终确定岩体力学参数提供重要依据。基于引入的岩体体积节理数Jv和结构面条件因子JC量化的GSI(地质强度指标)围岩分级系统和Hoek-Brown强度准则来估计岩体力学参数,并结合具体的工程估算岩体的力学参数验证应用效果,其成果对工程设计和施工有重要指导意义。

| Abstract: | Compared with Mohr-Coulomb strength criterion,Hoek-Brown strength criterion considers more influential factors such as the rock structure,rock mass strength,rock mass stress state,and so on.It reflects the nonlinear failure characteristics more accurately and consists with practical rock engineering much better.The estimated mechanical parameters of rock masses based on Hoek-Brown strength criterion could provide important reference for ultimate determination mechanical parameters of rock masses.A quantitat... |
