摘　　要：以济南地铁1号线为工程背景,通过土体强度、稳定性理论分析结合数值模拟,确定理论加固范围,结果表明横向加固宽度2 m,纵向加固长度8.4 m为富水卵石地层合理加固范围,以期为相关地层加固范围提供借鉴。Based on the engineering background of Ji’nan Metro Line 1,the theoretical reinforcement range is determined through the theoretical analysis of soil strength and stability combined with numerical simulation.The results show that the transverse reinforcement width of 2 m and the longitudinal reinforcement length of 8.4 m are the reasonable reinforcement range for water-rich pebble strata,hoping to provide reference for the reinforcement range of related strata.
