摘要
软地基条件下沉降监测网的点位精度及可靠性分析,是保证变形处理数据准确性的重要条件。利用3种平差数学模型(基准)进行观测基准网的解算精度比较,结合实例,提出了选用拟稳平差,处理软地基条件下沉降监测网的解算方案。
The precision and reliability analysis of points in settlement monitoring network is an important factor to guarantee the accuracy of deformation process data. Using the three adjustment model, this paper compared the precision of observation datum network. Combining a practical example, this paper brought forward a solution of network which is based on selecting Quasi - stable adjustment method and can deal with soft ground case.
