摘要
通过对红土岭隧道出口超浅埋洞顶膨胀土特性、变形规律进行分析,针对超浅埋、膨胀土地层地表水对隧道开挖施工的影响,详细阐述洞顶防排水技术、措施及实施效果。
This paper analyzes the characteristics and deformation laws of the expansive soil in the ultra shallow buried tunnel at the exit of the red niling tunnel.In view of the influence of the surface water of the super shallow buried and expansive soil layer on the tunnel excavation,the paper expounds the drainage technology,measures and implementation effect of the tunnel.
