吴江市地面沉降与开采地下水关系的研究

Relationship between Ground Settlement and Groundwater Exploitation in Wujiang City

对吴江市地面沉降与开采地下水关系的研究表明 ,地面沉降量在时空分布上与地下水开采量基本一致 ,地面沉降速率与地下水位呈明显的相关性。地下水累计开采量与地面累计沉降量有较好的相关性。运用太沙基的有效应力原理及一维固结理论 ,对地面沉降极限量进行估算 ,提出了控制地面沉降的措施。

A study on the relationship between the ground settlement and groundwater exploitation in Wujiang City reveals that the amount of ground settlement is consistent in space time distribution with the volume of water exploitation, that the rate of ground settlement is obviously related to the groundwater table, and that there is good correlativity between the cumulative volume of groundwater exploitation and cumulative amount of ground settlement. By use of the Terzaghi Effective Stress Principle and the theory of one dimensional consolidation, the ultimate ground settlement is estimated, and some measures are proposed for control of ground settlement.
