摘要
以等影响原则为前提,分析了基坑位移监测方法、差分测量原理及精度。利用基准点的已知信息,实现位移监测点的差分计算与数据处理。从而提高基坑位移监测精度。通过对比分析和实际工程应用表明,该方法对基坑位移监测完全满足规范要求,方便灵活,具有较好的应用价值。
On the assumption of equal influence, this paper introduces a method of foundation pit deformation measurement which includes the principle and accuracy of differential measurements.According to the given information of datum point,the differential computation and data processing can be conducted to calculate displacements of monitoring points and improve measurement accuracy of the displacements. Comparative analysis and practical engineering applications show that this method is convenient and flexible,fitting the specifications adequately,which has good application values.
