边坡三维稳定分析是一个复杂问题，以某大型溢洪道边坡楔体稳定性研究为工程实例，基于GIS数据平台进行边坡三维稳定极限平衡分析，经过数据的获得、空间处理、模型建立和安全系数计算，不仅得出了边坡的安全系数，而且给出了危险滑动面的滑动力大小和滑动方向分布，并根据锚索与软弱地层的空间位置关系，给出了锚索支护的调整方案。

Three dimensional slope stability analysis is a very complex issue. Setting research on the stability of a wedge on the large spillway slope as an engineering example,based on GIS,we approached to the use of three-dimensional slope stability limit equilibrium analysis. After data ac-quisition,spatial processing,modeling and safety factor calculation,we not only drew the safety factor of the slope,but also showed the distribution of the sliding forces and their direction on the critical sliding surface. And then,in accordance with the spatial relationship between weak layers and anchors,we proceeded the anchor support adjustment programs.
