淤泥质地层明挖隧道基坑围护结构受力分析

随着我国东部沿海地区城市的高速发展,城市地铁隧道区间不断在近海岸开工建设,由于近海岸地层以淤泥质黏土为主,如若处理不当,极易造成明挖基坑垮塌。为此,依托深圳地铁在建明挖地铁隧道区间基坑工程,采用数值计算分析方法,通过分析在建隧道区间基坑周边复杂环境,重点研究了淤泥质黏土地层对基坑建设的影响。

With the rapid development of the coastal cities in the east, the urban subway tunnels continue to be built on the coast. Due to the silt clay in the coastal strata, it is easy to deal with the excavation pit. In this paper, the influence of silty clay stratum on the construction of foundation pit is studied by analyzing the complicated environment surrounding the foundation pit of the tunnel under the foundation of the foundation pit of the Shenzhen Metro.
