某尾矿库初期坝采用分段施工，可能产生不均匀沉降，影响坝体的稳定性。采用孔径雷达干涉技术对尾矿库初期坝进行了短期变形速率观测，得出坝体右侧的后期填筑区域整体上与主体仍能够基本保持同步沉降。建立了三维流固耦合模型，分析了尾矿库初期坝的静力稳定性和渗流稳定性，结果表明：初期坝体的水平位移和竖向位移都在安全范围之内，考虑水和尾砂的共同作用，后期堆积坝堆积至1765m高程时，坝体顶部和后期回填区域，存在小量位移变形，静态稳定性安全系数达到2.25，初期坝能够保持稳定。

The initial dam of a tailings reservoir has been constructed in sections , and the differential settlement may affect the stability of dam body .A short-term observation for deformation rate of the initial dam was implemen-ted by INSAR, and the conclusion showed that the different area of dam body can keep pace with subsidence .Fur-thermore , a 3 D fluid-solid coupling numerical simulation model was established to analyze the stability of initial dam, and the conclusion showed that both the lateral displacement and vertical displacement of the dam body are within safe limits, and when the dam rises to the final attitude of 1765m, the safety factor of dam stability can reach 2.25, so the initial dam can be safe .
