沉降观测在“鑫润北国之春”高层建筑施工中的应用

Analysis on Application of Settlement Observation in High Building Named “Xinrunbeiguozhichun”

摘要:

城市高层建筑物变形监测是从施工到竣工直至稳定阶段进行周期性的沉降观测，目的是指导合理的施工工序，预防在施工过程中出现不均匀沉降，避免因沉降原因造成建筑物主体破坏而导致巨大经济损失。该文详细介绍沉降观测基准点、沉降观测点布设过程及观测方法，介绍使用的观测仪器、计算软件及观测精度；结合等值线图、楼载荷-时间-沉降量关系曲线图作楼基变形沉降分析，分析出现不均匀沉降现象的原因，并提出预防和解决问题的方法。

Abstract:

Deformation monitoring of urban high buildings is the periodic settlement observation from the period of construction, completion to stable phase. Its purpose is to guide the rational construction process, preventing uneven settlement, and avoiding damage and huge economic losses caused by the settlement. In this paper, datum marks of settlement observation, layout of observation points, observation methods, observation instruments, calculation software and observation precision are introduced. Combining with contour map, floor load time and settlement curve, deformed settlement analysis of building base is carried out, the reasons which caused uneven settlement are analyzed, and countermeasures for preventing and soluting the above problems are put forward as well.
