中文摘要: |
岩体的完整性和渗透性对水电工程防渗排水系统的设计具有重要意义,而钻孔压水试验是通常用来测定裂隙岩体透水性的方法之一。考虑到裂隙岩体渗透特性的空间分布与其所在坝址区的地质条件、风化卸荷作用等密切相关,本文将以某水电站工程区裂隙岩体为研究对象,在已有地质勘察资料的基础上,采用压水试验和统计分析相结合的方法,进一步开展天然条件下无卸荷微新岩体和风化卸荷岩体渗透性特征研究,并评估钻孔压水试验在西南峡谷区水电工程中的重要应用。 |
英文摘要: |
The integrity and permeability of rock masses is vital to the design of seepage control system for hydropower projects,water pressure test in borehole is one of the method to assess the hydraulic properties of rock masse.Considering the permeability distribution of fractured rock masses is strongly related to the geological settings and stress release effect,this paper took the fractured rock masses of a hydropower station as the research object,combining the techniques of water pressure test with statistical analysis based on thehydrogeological analysis,in order to analysis the fractured rocks in stress release zone and the deeply seated rocks ,and evaluate the significant application of data results for the hydropower projects in the Southwest valleys |
