岩质边坡的稳定性主要由其结构面控制,应用有限元分析岩质块体稳定性,具有可充分考虑岩体结构面间的相互作用,可反映边坡失稳以及塑性区的变化过程,能较好地反映岩体失稳的机理。结合广东省清远~连州一级公路升级改造工程中遇到的大量的裸露挖方路基边坡现状,采用有限元法分析岩体的稳定性,可为岩质边坡的设计、支护加固和施工提供一定的理论依据。
The stability of rock slope is mainly controlled by its structural plane. Finite element analysis of rock block stability can fully reflect the interaction between rock mass structural planes and reflect the instability of slope and the change of plastic zone , Which can well reflect the mechanism of rock instability. Combined with a large number of bare excavation subgrade slope encountered in the Qingyuan ~ Lianzhou highway upgrading and reconstruction project in Guangdong Province, the stability of rock mass is analyzed by finite element method, which can be used for the design of rock slope, reinforcement and Construction to provide some theoretical basis.
