单点位移法在沉降变形监测中的应用

摘要

在变形监测网中，由于外界因素等影响，很多情况下很难确定网中的基准点是否稳定，而基准点的稳定性对变形观测的数据处理的可靠性有很大影响，本文通过采用单点位移法对某实例数据进行分析，试验表明单点位移法有效的发现了动点，但在数据复杂时宜采用多种方式共同探测。%In deformation monitoring network, because of the influence of external factors and so on, in many cases it is difficult to determine the reference point in the net is stable, and the stability of the datum of deformation observation has a great impact on the reliability of the data processing, the single point displacement method through the use of an instance data were analyzed, and the ex-periments show that single point displacement method effectively find the fixed point, but in common detection data of place in many ways.
