太白县石沟水库坝基深埋强透水层成因及工程处理对策分析

Analysis on Genesis of Deep Buried Strong Permeable Layer in the Dam Foundation ofShigou Reservoir in Taibai County and the Countermeasures of Engineering Treatment

通过对水库坝基深埋强透水岩层的平面分布、空间发育、形成机理及其透水原因的深入分析论述,采用钻探、物探及联通试验等多种手段相互印证分析,阐明强透水岩层的地质特征,综合评价其对成库条件、坝基稳定的影响,并合理提出水库工程中坝基防渗处理对策。此为水库工程的设计、施工起到重要的指导作用。

In this paper,the plane distribution,spatial development,formation mechanism and permeable cause of the deep buried strong permeable rock layer in the dam foundation of the reservoir are analyzed and discussed in depth,and various means such as drilling,geophysical exploration and connection test are used to confirm and analyze each other.This paper expounds the geological characteristics of the strong permeable rock stratum,comprehensively evaluates its influence on the reservoir forming conditions and dam foundation stability,and reasonably puts forward the dam foundation anti-seepage treatment measures in the reservoir engineering.It plays an important role in the design and construction of reservoir engineering.
