摘要
城市供水工程的输水管线一般都很长,管辖范围大,沿途地形复杂,而隧洞是其中主要的水工建筑物。大量研究表明,裂缝是水工混凝土建筑物(包括隧洞)最普遍、最常见的病害之一,不发生裂缝的混凝土建筑物是极少的。隧洞混凝土裂缝往往是多种因素联合作用的结果。本文分析了东江水源一期工程隧洞产生裂缝的主要原因,提出了城市供水隧洞裂缝处理的特点和前提条件,为制定合理的修补方案提供了依据。
Generally, the conveyance line of a water supply project for cities is very long. It covers a large area and often has very complex topography. Tunnel is often to be the main structure in water supply projects. Many cases have demonstrated that cracking is a widely encountered problem in hydraulic structures （including tunnel）. The cracking of tunnel concrete is a result of multiple factors. In this paper, the main reasons of.the tunnel cracking at the 1^st stage Dongjiang Water Source Project were analyzed. The characteristics and the pre-conditions for treatment of the tunnel were presented. They could provide a good reference for setting a reasonable rehabilitation design.
