摘要
通过浅层地下水压力回灌对比试验研究,掌握上海地区特殊地质条件下浅层地下水回灌技术工艺,并对浅层地下水压力回灌技术控制地面沉降的效果进行了分析。研究表明,采用变压力、变流量地下水人工回灌可有效实现地下水位和地面沉降的双重控制,效果显著,可有效应用于上海地区地下空间开发引发的工程性地面沉降防治实践。
Through exploratory research on shallow aquifer pressure groundwater recharge experience,superficial groundwater recharge technique and process have been learned under special geological conditions in Shanghai,whose effect of controlling engineering land subsidence have been analyzed.It was shown that superficial groundwater recharge with variational pressure and flux can realize dual control of groundwater level and land subsidence.This technology can effectively prevent and control engineering land subsidence caused by ground space development in Shanghai.
