住宅项目沉降后浇带提前封闭的探究与应用
Exploration and Application of Early Closure of Post Settlement Pouring Strips in Residential Projects

高层住宅项目主楼与地下车库荷载差异较大，为应对由此产生的建筑不均匀沉降问题，设计一般会采用沉降后浇带。传统沉降后浇带封闭时间要求严格，沉降后浇带长期不能封闭会对现场施工进度与场地排布等方面带来不利影响，其矛盾已日益凸显。本文以华侨村二期项目为实例，采用数值模拟的方式模拟建筑沉降变形，探究提前封闭沉降后浇带的可行性，为优化沉降后浇带封闭时间提供参考。
There is a significant difference in load between the main building and the underground garage of high-rise residential projects. In order to address the problem of uneven settlement of the building caused by this, the design generally adopts settlement post pouring strips. The sealing time requirements for traditional settlement post pouring strips are strict. The long-term inability to close the settlement post pouring strip will have adverse effects on the construction progress and site layout, and its contradictions have become increasingly prominent. This article takes the Overseas Chinese Village Phase II Project as an example and uses numerical simulation to simulate building settlement deformation, exploring the feasibility of early closure of settlement and post pouring strips, and providing reference for optimizing the closure time of settlement and post pouring strips.
