地面沉降对太原市城市建设的影响及防治对策

Effect of land subsidence on the city construction of Taiyuan and the preventive countermeasures thereof

太原市地面沉降发展历史主要分4个阶段,通过对各阶段的各沉降漏斗中心地下水水位变化与地面沉降速率间关联性的分析,说明超采地下水是太原市地面沉降的主导因素,但仍然受地层岩性分布的深刻影响及其他因素的共同作用.从太原市建设现状与规划角度进行了地面沉降灾害分析,系统总结了太原市历年来地面沉降的防治措施并分析其效果,提出了太原市下一步需要加强及推动的地面沉降防治工作.

The developing history of land subsidence in Taiyuan can be divided into four main phases. An correlation analysis of the underground water level changes in each subsidence funnel center and land subsidence rate in each stage showed that the land subsidence in Taiyuan has been mainly caused by groundwater overdraft, and also been deeply influenced by stratigraphic distribution and other factors. Land subsidence disasters were discussed from the perspectives of city construction and urban planning of Taiyuan, and the preventive countermeasures and effect of land subsiding in the past years were also summarized, suggesting that ground subsidence prevention and control work in Taiyuan should be strengthened in the future.
