摘要
成都地铁富水砂卵石地层采用土压平衡盾构法施工时,存在着比较特殊的滞后沉降现象。结合成都地铁施工的实践经验,分析了富水砂卵石地层施工滞后沉降的产生机理,研究并总结了预防控制滞后沉降的措施,为国内类似工程滞后沉降的预防控制进行了初步的探索。
Special delayed settlement appeared when EPB shield tunneling method was used in the water-rich sandy cobble stratum in Chengdu Subway.This paper analyzes the cause for the delayed settlement in water-rich sandy cobble stratum,researches and concludes the prevention and control measures for the delayed settlement based on the construction experience in Chengdu Subway project.It sheds light on similar prevention and control measures for the delayed settlement in China.
