建筑物变形观测及数据分析

Observation and data analysis of building deformation

本文以湿陷性黄土地区的某建筑物为研究对象,通过对其沉降后引起的楼体变形进行观测,设计了以变形测量和工程测量规范为依据的变形测量实施步骤。对测得的观测数据进行了沉降量、沉降速率、沉降趋势以及"时间-沉降"关系分析。在此基础上,对建筑物加固施工后的稳定性做出了分析和判断。

This research was based on the observation of a building in the area of collapsible loess. According to the Standard of Deformation Measurement and Engineering Surveying, this article pur- posed the implementation steps of deformation measurement, analyzed the data of settlement, settle- ment rate, settlement trend and relationship of time - settlement, and made the conclusive analysis and judgment of the stability of the building.
