摘要
地下建筑工程裂缝80%以上由变形引起。采用以放为主的设计原则,在规划部位以多设缝的方法释放混凝土的内应力,可以达到控制和减少无序裂缝产生的目的。而地下建筑工程中,缝的防水又是一大难题,针对地下工程中几种常用缝的防水方法进行分析,在参考了日本防水做法的基础上,结合我国工程应用实例,提出各种缝的优化防水设计方法。
80% cracks of underground project are caused by deformation.In order to control and reduce casual cracks,the design principle of 'release' can be adopted and the internal stress of concrete can be released by setting construction gaps within the planned locations.Waterproof design is another challenge of underground project.Analyses were performed with respect to the waterproof design methods for several common joints.With reference to the waterproof technology in Japan,and also combined with actual projects in China,the waterproof design optimization methods were proposed for various joints.
