裂隙岩体的水力劈裂分析
|
摘要
随着水电工程建设、地下核废料储存、地热开发、矿井采掘等岩体工程越来越多的处于高水头、大埋深等恶劣水文地质条件下,水力劈裂作用正在受到越来越多岩体工程稳定性研究者的关注。本文主要研究裂隙岩体的材料和力学特性以及裂隙岩体的数值模型与数值分析,并通过工程实例提出了作者的见解;最后展望了水力劈裂的前景和提出几个重要的待解决问题。
More and more rock mass engineering under the high water pressure and deep burying with wicked hydro- geological conditions such as the hydropower construction, storage of underground nuclear waste, geothermal develop- ment, mine excavation. The role of hydraulic fracturing the role of hydraulic fracturing is being concerned by more and more researchers who research on stability rock mass engineering stability. This paper research on material, mechanical properties, numerical model and numeric analysis of fractured rock mass, then put forward the suggestion through some engineering cases. In the end of this paper, it expresses the prospect of hydraulic fracturing and raises several important questions to be solved.
