对露天矿边坡实时、精确测量可以为边坡治理和预警提供可靠的信息,直接关系到露天矿的经济效益和生产的连续性.本文提出采用地基合成孔径雷达干涉测量技术（GB-InSAR）监测露天矿边坡,和常规测量方式相比,该技术具有高的空间分辨率和测量精度,实现与地形无关的差分干涉技术,能够获得多时相形变图和形变速度图,反映边坡的整体位移趋势,为露天矿边坡的运动历程分析提供了可靠的信息,并通过实验验证了GB-InSAR技术监测边坡的可靠性.

英文摘要：

A real-time, accurate measurement of slope of open pit could provide reliable information for slope management and the warning system, directly related to the economic benefits and production continuity in the open pit. This paper proposed an innovative technique, based on synthetic aperture radar interferometry and implemented using ground-based instrumentation, has been applied for monitoring slope of open pit. Compared to conventional measurements, The proposed technique presents high spatial resolution and accuracy, generates a topography-free interferogram, provides multi-temporal displacement and velocity map, supplies a deformation field of slope, which represents reliable information for the interpretation of slope kinematics and short-term evolution. The experiment shows that the new technique is reliable for monitoring slope of open pit.
