根据监测基坑的大致情况进行分析研究,在此基础上制定可行的监测方案;通过电子水准仪测量监测点位沉降、精密全站仪测量监测点的水平位移、测斜仪监测土体倾斜位移、应力计测量土应力变化。按照测量规范,定期内对监测点进行测量,记录。对监测的数据进行处理和分析,利用多项式拟合建立监测模型,最后进行监测结果的分析。

According to the analysis of the general situation of foundation pit monitoring, a feasible monitoring plan is established based on this. The settlement of monitoring point by electronic level, the horizontal displacement of monitoring point by precision total station, Stress gauges measure changes in soil stress. In accordance with measurement specifications, regular monitoring points on the measurement, recording. The monitoring data processing and analysis, the use of polynomial fitting to establish a monitoring model, the final monitoring results of the analysis.
