摘要
随着城市人口的日益增长和城市规模的不断扩大,诸多沿海城市采用填海方式扩大城市陆用面积。鉴于临海地区特殊的地质条件和复杂的周边环境,如何有效减小地铁施工对淤泥地层的扰动,保证其可靠的稳定性和安全性是填海区地铁施工必须克服的难题。以深圳地铁1号线续建工程鲤鱼门站为依托,讨论和总结在淤泥地层地铁车站基坑开挖采用的施工方法和成功经验。
With the growing population and the increasing urbanization scale, many coastal cities have to expand land by backfilling the sea. Considering the special geological conditions and the complex surrounding environment of the waterfront areas, how to reduce the disturbance of the silt effectively and ensure the stability, reliability and safety in reclamation areas is a big challenge that subway project has to deal with. In this paper, construction methods and successful experience of the pit excavation in the sludge formation is discussed and summarized based on the Shenzhen metro Line 1 extension project of Liyumen Station.
