测斜数据改正方法在基坑监测中的应用

Application of Inclinometer Data Correction in Foundation Pit Monitoring

以上海某在建基坑为例,为解决测斜管埋设时方向偏移而造成数据不准确的问题,提出一种测斜数据改正方法,并对改正后的数据与实测数据进行对比分析。工程实例应用表明:改正后的数据可以较好地反映基坑变化趋势;该改正方法在基坑监测中的应用是可行的。

Taken a building foundation pit in Shanghai as an example, in order to solve the problem of inaccurate data caused by the deflection of inclinometer tube while it is buried, a method for correcting the inclinometer data is proposed and the contrast test is carried out between the corrected data and the measured data. It is demonstrated that the corrected data can better reflect the tendency of the foundation pit. It shows that the correction method is feasible in the foundation pit monitoring.
