【摘要】 地面沉降是城市主要地质灾害之一。随着中国城市化进程的加快,地面沉降规模扩大,危害加剧。本文简述了国内外地面沉降概况,对地面沉降的成因、危害、机制、数学模拟、监测、防治等方面的研究进展进行了综合论述;并指出,建设工程性地面沉降、孔隙水运移机制、地下水和地面沉降模型耦合、地面沉降生态—经济—社会影响评估、地下水采灌优化设计、地面沉降系统防治、地面变形高精度监测、城市化建设与地面沉降的相互关系等,是今后城市地面沉降研究的主要方向。更多还原

【Abstract】 Land subsidence is a major urban geological hazard at home and abroad. With the accelerating of urbanization in China, the scale of land subsidence is enlarging and the harm is aggravating. On the basis of brief introduction of general situation on land subsidence at home and abroad, the advances in forming causes, harm, mechanism, mathematical simulating, monitoring and control on land subsidence in the World have comprehensively been summarized and the principal research directions about land subsidence in the future, which is land subsidence resulting from urbanization and engineering construction, porous water migrating mechanism, model coupling on groundwater and land subsidence, affecting assessment on ecology-economy-sociaty resulting from land subsidence, optimization design on exploitating and artificial recharge of groundwater, systematic control on land subsidence, high precision monitoring on land deformation, mutual relation between urbanization construction and land subsidence, etc. , have been put forward in this paper.更多还原
