地下混凝土工程抗裂研究

Anti-cracking research on underground concrete projects

目前我国地下工程以高层建筑地下室居多,地下室多数存在防水问题,而防水的关键在于抗裂和抗渗。混凝土抗渗问题现已能解决,抗裂问题则一直困扰工程界多年,未能很好解决。本文主要从设计角度并结合工程实践经验,推导出地下室底板和外墙的裂缝间距计算公式,供设计参考。

Nowadays more and more underground projects are basements of high-rise buildings. Most of the basements encounter waterproof problems, the keypoint of water proofing lies in anti-cracking and anti-seepage. Now the problem of anti-seepage has been solved, but the problem of anti-cracking still remains, and it brings much problems to the construction industry. This paper deduce a formula to calculate the disdance of cracks in basement slab and walls based on the experience of the auther and hopefully it can be a good reference.
