水利水电工程喀斯特地质缺陷处理措施实践

Practice of treatment measures for karst geological defects in water conservancy and hydropower projects

我国西南地区碳酸盐岩广布,喀斯特形态各异,星落密度,形成了众多美妙的地质奇观,也给众多工程建设过程及安全运行带来困扰。本文以旧司水库左坝肩基础开挖揭露的隐伏喀斯特地质缺陷对工程建设及安全运行的影响分析,以及工程处理措施建议为例,论述当工程建设与喀斯特地质缺陷冲突,只能通过合理的工程处理措施来满足建(构)筑物基础承载力、防止库水渗漏等条件的工作思路,为工程的顺利建设及安全运行提供重要保证。

Carbonate rocks are widely distributed in southwest China,KRAS is different,The stars are falling,To form many wonderful geological wonders,It also brings trouble to the construction process and safe operation of many projects.This paper analyzes the influence of hidden karst geological defects exposed by excavation of left abutment foundation of Jiusi reservoir on the construction and safe operation of the project,And proposed engineering measures as examples,On the conflict between,engineering construction and geological defects in Kras,The bearing capacity of building(structure)foundation can only be satisfied by reasonable engineering treatment measures Working Thought of preventing reservoir water leakage and other conditions,For the smooth construction and safe operation of the project to provide an important guarantee.
