摘要
混凝土结构设计中,采用以"放"为主的设计原则,通过设缝的方法释放混凝土的内应力,可以控制和减少混凝土结构无序裂缝的发生。而地下建筑工程中,缝的防水又是一大难题,本文着重针对地下工程中几种常用缝的防水方法进行了分析,在参考日本防水做法的基础上,结合我国工程应用实例,提出了各种缝的优化防水设计方法。
＂Release＂ is a major principle in the design of concrete structure. Through the construction joints, the internal stress of concrete can be released. In this way, unordered cracks in the concrete structure can be controlled or reduced. Nevertheless, waterproofing for the joints is a major challenge in underground constructions. This article analyses some waterproofing solutions for the common joints in underground constructions, and points out optimized waterproofing designs for various joints with references of Japanese practices and cases in our country.
