摘　　要：通过地质调研,分析了大冶铁矿滑坡体破坏特征和成因.根据滑坡发展过程表现出来的破裂扩展极限特征,建立了滑坡位移、变形速率、蠕变切线角、位移加速度、位移矢量角变化趋势曲线.运用数理统计,将多参数进行联合分析,提出了滑坡的综合预报判据,为滑体后续监测提供了科学的理论和实际依据.The characteristics of slope deformation and failure, the causes of landslide damage were studied through geological investigation in Daye Iron Mine. According to the limit characteristics of the development process, the trend curves of displacement, convergence velocity, creeping tangent-angle criterion,acceleration and displacement vector angles were deduced. On the basis of the mathematical statistics and multi-parameter analysis, comprehensive prediction criterion was discussed, which may provide scientific evidence for future monitoring.
