摘　　要：针对地下工程开挖引起的地表下沉问题,根据岩石流变学理论,给出地表下沉预计分析的粘弹性力学理论模型,并对工程实例进行了计算分析。将理论分析结果与现场工程实测资料对比,二者吻合较好,表明本文提出的方法可用于分析地下开采地表下沉问题。It is the purpose of the paper to discuss the problem of ground surface subsidence due to underground mining. According to the theory of rock rheology mechanics, the theoretical model for the predietion and analysis of the ground surface subside.nee is given. The agreement of the theoretical results with the filed measurements shows that the model is satisfactory and the formulae obtained are valid and thus can be effectively used for predicting the ground surface subsidence due to underground mining.
