跳仓法在超长混凝土底板中的设计与研究

Design and Researchof Sequence Construction to Super-long Concrete Foundation Slab

一般工程中对超长地下室主要采用设置施工后浇带的方式,从而释放施工阶段混凝土的收缩变形。但这种常规的处理方式存在一些设计和施工不足,给工程质量造成一定的隐患。论文以某工程项目为依托,对跳仓法进行了研究和应用。该方法避免了施工后浇带的设置,达到了良好的设计和施工效果。

In order to release the shrinkage deformation in concrete construction phase, the late poured band is always applied in super-long foundation slabs. But many disadvantages have been found in the process of design and construction, increasing the probality of safety risks. Based on an engineering project, the sequence construction has been conducted and researched. The application of the sequence construction gets perfect design and construction effect, insteading of the late poured band.
