【摘要】 地下工程深基坑施工中,为降低环境风险,应在保护建筑附近布设回灌井,实施人工地下水回灌,从而达到控制保护区地面沉降的目的。结合上海轨道交通13号线汉中路站基坑工程,介绍了在金峰大厦周边布设回灌井进行回灌的保护措施;通过抗承压稳定性验算,确定了不同开挖深度下的承压水水位控制要求;验证了回灌对控制地下水位和地面沉降的效果。更多还原

【Abstract】 In the construction of deep excavation of underground engineering, the recharge wells should be set near the protected building to reduce the environmental risks. And the ground settlement of the protected area is controlled through recharge groundwater. The excavation engineering of Hanzhong Road Station of Shanghai Rail Transit Line 13 is introduced. During the construction, the recharge wells are set around the Jin Feng Mansion close to the station. Through the stability checking, the control requirements of confined water level under different depths of excavation are determined; and the effect of recharge on the control of groundwater level and ground settlement is verified.更多还原
