摘要
针对长沙轨道交通1号线砂卵石地层区域段,文中阐述了对于下穿建构筑物地段及地质条件突然变化区段,不只是简单地套用砂卵石地层控制参数,而需要通过精细化施工及调整掘进参数,并提前对地层采取预处理措施。
In view of the sandy cobble stratum area section of Changsha Rail Transit Line 1, this paper expounds that for the section passing through buildings and structures and the section with sudden change of geological conditions, it is not only necessary to simply apply the control parameters of sand gravel stratum, but also need to fine construction and adjust the driving parameters, and take pre-treatment measures for the stratum.
