裂隙岩体坝基渗流分析成果是进行大坝工程设计的重要依据之一。本文对三峡双线五级船闸基础排水廊道渗流监测成果进行分析;对关于船闸基础排水廊道渗流量情况进行说明并分析;检修后对混凝土结构缝止水单元外漏施工进行评价。
The result of seepage analysis of dam foundation of fractured rock mass is one of the important bases for dam engineering design. This paper analyzes the monitoring results of the seepage flow in the foundation drainage corridor of the Three Gorges double-line five-stage ship lock, explains and analyzes the seepage flow of the foundation drainage corridor of the ship lock, and evaluates the leakage construction of the water stop of the concrete structure sewer after the overhaul.
