Key Construction Technology of Large-scale Underground High-speed Railway Station in City Center District

广深港客运专线福田站是目前国内最大的地下高铁车站,地处超高层建筑林立的深圳市中心区,本工程施工中以确保周边建筑物及施工安全为目的,在采用盖挖逆作及明挖顺作2种施工方法的施工过程中,通过对深基坑围护结构变形、地面沉降实时监测数据的处理分析结果,决定采取各种不同的控制基坑变形的技术措施,有效地控制了深基坑变形,保证了周边建筑物和施工的安全。

Futian Station in Guangzhou-Shenzhen-Hong Kong Passenger-dedicated Line is the biggest underground high-speed railway station in China,and is surrounded by the high buildings in center business district of Shenzhen.During construction with Cover-cut Method and Open-cut Method,the countermeasures enlightened by analysis result of monitoring data on the deformation and settlement of the deep foundation pit were employed.As a result,the deformation of the deep foundation pit is controlled effectively,so the safety of the construction and surrounding buildings are guaranteed.
