平班坝址水环境对水工建筑物的影响分析

Analysis on Impact of Pingban Damsite’s Water Environment on Hydraulic Structures

针对平班库区水和坝基廊道渗漏水以及坝基析出物的水质特征、水质演变的情况进行分析。从而了解大坝周围环境水对混凝土的影响及坝内防渗帷幕的微观状况,找出了不利于大坝长期安全运行的因素,为可能采取的工程补强措施提供了科学依据。

An analysis is made on quality characteristics and evolutions of reservoir water, dam foundation corridor seepage and dam foundation precipitations of Pingban hydropower station. Therefore, the factors, those are not con- ductive to the long-term and safe operation of dam, are identified based on the understandings on the impact of water environment on concrete and the microscopic conditions of anti-seepage curtain inside dam, which provides a scien- tific basis for engineering reinforcement measures may be taken.
