Experiments and Study on Anti-Cracking Technique for Concrete in Lock-Chamber Walls of Second Ship Lock in Jianbi on Beijing-Hangzhou Grand Canal

大体积混凝土存在裂缝在水利水运工程中是常见的现象 ,本文着重介绍了谏壁二线船闸闸室墙施工中 ,采用两种防裂混凝土与普通混凝土的对比试验研究 ,分析裂缝产生的原因 ,提出相应的建议 。

It is common that cracks develop in mass concrete in hydraulic and waterway engineering works.The paper emphasizes on the experiments and study carried out to compare two types of anti cracking concrete with the ordinary concrete during the construction of the lock chamber walls of the second ship lock in Jianbi on Beijing Hangzhou Grand Canal.With the analyses of the causes resulting in cracking in concrete,recommendations are also made to deal with cracking in concrete accordingly,which will be of reference for other ship lock projects.
