摘要
通过某工程超长地下室在设计时的温度应力控制分析,提出了利用结构板面标高变化及混凝土侧壁折角释放温缩应力的方法,结合合理设置后浇带和加强施工养护等措施,释放施工阶段的温缩应力和混凝土干缩应力,形成多层次多梯度的收缩应力控制方法。
By the analysis of the overlong basement of a hospital,this paper put forward the method of using the elevation changes of the concrete board to release the shrinkage stress of overlong concrete. Combined with the after pouring belt methods and conservation measures,the release temperature shrinkage stress and drying shrinkage stress of concrete construction phase,thus forming a multi-level gradient shrinkage stress control methods.
