摘　　要：地下工程施工、开发地下资源(包括开采地下水),都会导致地下出现地下空间,引起位于地面的城市、交通线路及水体发生沉降。基于褶皱地层出现地下空间时的地面沉降规律,研究非层状地下空间的表述和处理方法。根据非层状地下空间投影方法,确定了非层状地下空间投影的基本形状和积分区间,推导出非层状地下空间形状系数的计算公式。Underground construction, mining and excessively pumping groundwater are probably led to occur underground room. The subsidence of cities and towns, traffic lines and waters in ground are caused by underground room. Based on the principle of surface subsidence under folding bedded shape room, the methods of describing and disposing the non-bedded shape room are studied in this paper. According to the projection method of non-bedded shape underground room, the primary shapes and integration limits of the projection of the non-bedded shape underground room are determined. And also the computational formulas of the shape coefficients of the non-bedded shape underground room are deduced.
