摘要
针对变形监测网数据处理时判断基准点是否稳定可靠的情况,提出了一种平均间隙法和单点检验法相结合的变形分析方法.通过对某一沉降监测网的两期观测进行平差计算,将不稳定的基准点剔除,避免了用不稳定基准点给变形计算带来偏差,提高了变形分析预报的准确性和科学性.
According to judging whether the control points are stable and reliable in data processing of the deformation monitoring network,a method combined the method of mean GAP with the single point inspection is presented.By two-stage observation adjustment calculating of a settlement monitoring network,the unstable control points are eliminated,which avoids bringing deviation to the deformation calculation by using the unstable control points,and further improves the scientific accuracy of deformation forecasting and analysis.
