摘要
结合小浪底地下厂房及江阴大桥等国家重点工程的岩体稳定性研究 ,对层状裂隙岩体稳定分析中的地质模型、计算参数及计算方法等主要问题作了探讨。提出了建立概化地质模型及计算参数的多种方法综合取值 ,并采用考虑结构面变形的非线性有限元分析方法等 ,计算结果与施工监测成果基本吻合。
Combining with research on the stability of rock mass in two state key projects,i.e. underground building of Xiaolangdi and foundation o f Jiangyin Bridge,the main problems of stability analysis of layer jointed rock mass such as geol ogical model, calculating parameter and method are discussed. The establishment of geological model and integrating method for determination of calculating para meter is proposed. By using the method of non-liner FEM with consideration of the deformation of geological structural plane, the results agree approximately wi th the monitored results during construction.
