Study on optimized strategy of groundwater recharge for land subsidence control in Shanghai
摘要
Abstract
Land subsidence is the primary geological hazard in Shanghai,posing a long-term serious threat to urban safety and sustainable socioeconomic development.Although the subsidence rate has notably decreased,uneven subsidence remains prominent,demanding increasingly precise control and prevention measures.Currently,groundwater extraction and recharge are unevenly distributed across regions and aquifer layers,with localized groundwater depression cones persisting in certain areas.The existing extraction-recharge pattern still fails to meet subsidence control requirements.This study conducts an in-depth analysis of long-term groundwater and subsidence monitoring data in Shanghai,proposing an optimized groundwater recharge scheme.Using a three-dimensional groundwater seepage and one-dimensional subsidence coupled mathematical model,the scheme's effectiveness in mitigating subsidence was validated.Results indicate that reducing total annual recharge volume by 5%while strategically shifting recharge focus toward general subsidence control zones can achieve subsidence management targets while optimizing resource allocation.This optimized approach provides critical decision-making support for precision subsidence control and prevention.关键词
