高层建筑物沉降观测及形变分析

摘要

This paper introduces the technical requirement of high - rise construction settlement observation in the first place, then introduces settlement observation plan of the office building of Police Center of Tongzhou District of Nantong City. It focuses on the analysis of settlement observation data. The result shows that point ZL08 is the least stable, ZL02, ZL06, ZL07 points are next to it, ZL05 is the most stable point from the point of view of a single point, but the settlement value of all points%首先介绍了高层建筑物常规沉降观测相关要求，然后给出了南通市通州区公安局指挥中心大楼主楼沉降观测技术方案，并重点对沉降观测数据进行了研究分析，结果表明，就单个点而言，ZL08最不稳定，ZL02，ZIA36和ZL07次之，ZL05最稳定，但最终所有点都稳定在0～1mm区间内，按照主体结构封顶后一年内最后100d的沉降速率小于0．02mm／d，可认为该高层建筑物沉降稳定该大楼在观测周期内沉降形变稳定，符合建设要求。
