摘    要:狮子滩大坝是我国解放初期建设的,受当时坝工设计、施工水平的限制,大坝的防渗处理效果不甚理想,这是造成坝基扬压力部分超标的原因之一.另外,由于狮子滩大坝已运行多年,水库中有机质的富集致使下层库水弱酸性化和含侵蚀CO2.本文根据狮子滩大坝现有的资料初步分析了坝基扬压力超标的原因,并提出了处理意见.

关 键 词:狮子滩水库  坝基  扬压力超标  原因

Abstract:The shizitan dam was constructed in the 1950's.Because of the limit in aspects such as design and construction,the anti-seepage effect was not so good.This is one reason for the uplift pressure exceeded the standards.Furthermore,the dam has been in operation for many years,the organic items'concentration leads to the low-level reservoir water weak acidulated and eroded CO2.This paper,combined with the data of shizitan dam,analyzed the reasons for uplift pressure exceeded the standards at some dam blocks and advanced the treatment measures.
Keywords:Shizitan reservoir  dam foundation  uplift pressure  reason
