摘　　要：从地质学与力学的角度看 ,城市的不断扩展等同于城市建设对地质环境施加规模和强度不断增大的荷载 ,而城市下伏岩土体承受荷载的能力是有限的。本文由此侧面切入城市地质环境与地质灾害问题。注重潜在的、缓慢的城市地质作用。以承载能力的极限为研究目标 ,重在提示附加应力对地质介质力学性状的作用 ,并由此揭示对地基破坏、区域地面沉降、含水层状态。From the viewpoint of geology and mechanics, progressive enlargement of cities puts loadings on its geological environment. Actually bearings of the geomaterials in the environment are limited. This paper presents researches on the geological environment and geological hazards associated with the loadings and bearing limits in cities development. More attentions are paid on the potential geologic process with a slow rate in urban areas. Through finding out reactions of the geological media to overlaying additional loadings, this research aims at seeking bearing limit of geomaterials. As a result, the perturbation mechanism of the basement failure, regional ground subsidence, behaving status of aquifers, seismic wave transmission properties, and active faults reoccurrence, etc., are interpreted.
