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。
The main influencing radius is determined by using D-In SAR technology. Combined with the measured values of GPS, the estimated parameters of probability integral method are obtained. The predicted and measured errors are within 0.25 m. Experiments show that this method can be better applied to the surface of mining area Deformation of the settlement is expected.
