Sensitivity analysis of subsidence monitor and control network in buildings construction

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.
