摘要
沉降监测控制网是沉降监测的基准,控制点本身的沉降变化理应被及时发现。对沉降监测控制网进行灵敏度分析,主要是分析控制网能够发现控制点沉降量的最小值,这对保证沉降监测成果的真实可靠具有重要意义。结合某建筑小区群楼施工沉降监测控制网的复测结果,对控制网的灵敏度进行分析,及时发现控制点的沉降变化,保证沉降监测期间始终使用可靠的控制基准。
Subsidence monitor and control network is a fiducial network for subidence observation. The changes of control points should be found in time. The sensitivity analysis of this network is on the control points in order to know what is the minimum value of the subsidence, the accuracy and reliablity of subsidence observation. Based on the retest results from a local building construction, the sensitivity of this network is analyzed to detect changes thus guaranteeing, and to ensure reliable control data.
