砂卵石地层地铁盾构施工沉降处理技术

Settlement Treatment Technology of Metro Shield Construction in Sandy Gravel Stratum

砂卵石地层地铁盾构作业面沉降的处理效果,对地铁施工安全具有直接的影响。但是,现阶段砂卵石地层地铁盾构作业面沉降问题较为常见,一旦控制不当,极易引发地铁工期延滞。因此,以一个砂卵石地层地铁盾构项目为例,探讨了砂卵石地层地铁盾构施工沉降规律表现以及控制技术。希望为同类型砂卵石地层地铁盾构施工沉降处理提供参考,做好盾构期间沉降控制,把控技术质量,保障地铁工程安全稳定推进。

The settlement treatment effect of metro shield working face in sandy gravel stratum has a direct impact on metro construction safety.However,at this stage,the settlement problem of metro shield working face in sandy gravel stratum is relatively common.Once it is not properly controlled,it will easily lead to the delay of metro construction period.Therefore,taking a metro shield project in sandy gravel stratum as an example,this paper discusses the settlement law and control technology of metro shield construction in sandy gravel stratum.It is hoped to provide reference for the settlement treatment of metro shield construction in the same type of sandy gravel stratum,do well in the settlement control during shield construction,control the technical quality,and ensure the safe and stable progress of the metro project.
