东北某水电站34-36号坝段F67断层坝基地质力学参数复核和选取研究

Review and selection of geomechanics parameters of dam foundation of F_(67) fault at block No.34～36 of a hydropower station in Northeast China

坝基岩体地质力学参数是工程地质从定性判断到定量分析的基础,是提供设计的依据,也是大坝坝基工程地质勘察的核心之一。以东北某水电站为例,介绍坝基地质力学参数的复核及岩体物理力学指标选取原则,供工程地质人员参考。

Geomechanics parameters of rock mass of dam foundation are the basis of quantitative analysis and design, as well as the core content of engineering geological investigation. Case study based on a hydropower station in northeast China was carried out to study the review of geomechanics parameters of dam foundation and mechanics principle of rock mass, for reference.
