摘要
武汉地区地层复杂性是众人皆知的,而一级阶地中的互层土由于组成其土层的不同性质往往会给基坑工程施工带来困难甚至风险。通过对武汉轨道交通6号线某主体车站基坑工程在开挖过程中遇互层土时产生了较大变形的原因分析和处理措施,提出了在互层土中进行基坑施工应该注意的问题,这对类似基坑工程具有一定的借鉴意义。
The stratigraphic complexity in Wuhan is well-known, and the interbedded soil in the first terrace is often difficult or even risky to pit construction owing to the composition of different natures of the soil. Based on the reason analysis and treatment measures of large deformation of the foundation pit of a subject station of Wuhan Metro Line 6 in interbedded soil during the excavation, some problems that should be paid attention to in interbedded soil during the excavation are proposed, and it may provide certain reference for similar foundation pits.
