摘要
断裂构造是工程建设中经常遇到的一种地质现象,其渗透特性是影响水工建筑物渗流稳定的重要因素和勘察设计中的重要内容。以内蒙古某水库坝基发育的断裂构造——F1断层为例,在分析构造特征、发育规模的基础上,将断层影响带岩体划分为碎裂岩带、软弱构造岩带两种类型,利用压水试验成果分析评价其渗透性能、空间分布规律以及影响渗透性的因素,旨在为类似工程提供借鉴和参考。
Fault structure is a kind of geological phenomenon often encountered in engineering construction ,and its per-meability is an important factor affecting the stability of hydraulic structures .Based on the analysis of structural features and development scale , the F1 fault zone is divided into two types , which are cataclastic rock zone and weak tectonic rocks belt .Using the results of the pressure water test ,its permeability ,spatial distribution and the factors that affect the permeability are analyzed ,the purpose is to provide reference for similar projects .
