我国滨海城市地面沉降的研究现状与发展趋势以天津市为例

RESEARCH PROGRESS AND DEVELOPMENT TRENDS OF GROUND SUBSIDENCE IN COASTAL CITY TAKE TIANJIN COASTAL PLANE FOR EXAMPLE

摘要: 地面沉降是世界沿海城市主要的地质灾害,使得社会经济遭受严重损失,国内外进行了大量的研究。诱发地面沉降的最主要的因素就是对以地下水为主等地下流体的过度开发,因此如何控制地面沉降,协调地下水资源利用与城市发展的关系,减轻灾害程度成为现在的研究热点问题,同时也是关系着国家的战略需求。本文针对目前地面沉降的研究现状和趋势,笔者在归纳总结的基础上提出了新的研究思路,这对地面沉降的今后研究具有重要的指导意义。

Abstract: Ground subsidence is the major geologic disaster of coastal city in the world, which has brought about serious loss to the economy. Ground subsidence occurs when large amounts of groundwater have been withdrawn from certain types of rocks, such as fine-grained sediments. How to reduce the damage extent and to control the ground subsidence is a hot topic, which is closely related to the national economy and the public livelihood. In this paper, further studies in the field are pointed out.
