摘　　要：汉钢站的建立位于武汉市地铁12号线,此项目存在场地内土层条件复杂,主要为黏性土地质分布不均匀,且基坑周边环境复杂等问题。通过采用盖挖逆作法进行施工,基坑主体围护均采用地下连续墙+板支撑结构体系来控制周边的地表沉降的施工工艺。研究表明:通过地下连续墙技术和板支撑结构体系的加固方式,有效确保建筑安全,为类似工程提供基础。The Hangang Station was located on Wuhan Metro Line 12,and this project had complex soil condi-tions in the site,mainly the unevent distribution of cohesive soil geology,the complex surrounding environment of foundation pits,etc.The construction was carried out by the convered top-down excavation method,and the main enclosure of foundation pits adopted the construction technology of the underground diaphragm wall+the plate support structure system to control surrounding ground surface settlement.The results shows that the reinforcement method of underground diaphragm wall technology and the plate support structure system can effectively ensure the safety of buildings,which provides a foundation for similar projects.
