摘　　要：随着世界经济的发展、人口的膨胀以及城市化进程的加快,环境对人类的生产生活的制约性也日益加强,发生在新生代沉积软粘土地层上的地面高程损失(主要由地面沉降造成)成为世界性关注的重大环境问题之一。软粘土地层的地面沉降包括自然沉降和人为沉降两方面。因此,土力学者和地质学家从工程学界和地质-沉积两个不同的方面对地面沉降机制进行了研究,并且以对前者的关注为主。工程土力学中沉降的是由软粘土的固结压缩导致的。本文结合地质因素对发生在软粘土地层上的地面沉降问题进行了分析。With the world economic development, population expansion and the acceleration of urbanization process, the restrictions of human living and production is also increasing. The loss of ground elevation on the soft clay of Cenozoic sedimentary strata, which is mainly caused by land subsidence, becomes one of the largest global environmental problems. The land subsidence of soft clay is including natural and man-made content, which leads to the research on the mechanism of land subsidence constituted by two different aspects, which are studied by geological engineers and geologist. The main major research focuses on the effect of engineering. The land subsidence of soil in engineering mechanics is caused by the consolidation and compression of soft clay. The paper analyzes the loss of ground elevation from geological factors.
