基于D-InSAR和概率积分法的矿区沉降预计

Mining Subsidence Prediction Based on D-InSAR and Probability Integral Method

提出利用D-In SAR技术确定主要影响半径,结合GPS实测值,求取了概率积分法预计参数,预计值与实测值误差在0.25 m之内,实验证明该方法可更好地用于矿区地表形变的沉降预计。

D-In SAR technique is used to determine the main influencing radius, then combines GPS data, calculate the expected parameters by probability integral method to,estimated values and measured error within 0.25 m, it is better than expected curve which obtained by sinking curve. The experiment proved that the method can be used for predicting the subsidence of the surface deformation better.
