地下工程施工、开发地下资源(包括开采地下水)都会引起地面发生沉降,导致位于地面的城市、交通线路及水体随之沉降。这种工程性沉降问题产生的根本原因在于地下出现了空间,而非层状(即不规则形状)空间环境是一种普遍存在的情况,与层状空间环境的地面沉降机理不同。当地下出现非层状空间环境时,目前还没有实用的地面沉降预测模型,否则,把非层状地下空间简化为层状情形进行处理。基于地下出现褶皱层状空间环境时的地面沉降规律,研究非层状地下空间形态的表述和处理方法。
Underground construction, mining and excessively pumping groundwater cause the surface subsidence. The subsidence of cities and towns, traffic lines and waters are probably led to occur in the subsidence. The problem of subsidence is produced as a result of the underground-excavated rooms. The condition, which there is the non-bedded shape room or irregular shape room environments, exists in common. The bedded shape room environments differ greatly from non-bedded shape room environments in mechanism of sur...
