摘　　要：针对营盘路湘江隧道东岸小净距段的施工,文章对管线的安全性进行了对比分析,分别模拟了地表未加固条件下、地表加固条件下,小净距段隧道施工对上覆土层中管线的影响。Combined with the tunnel construction in east Xiangjiang,the safty of line is analysed in this paper.the numerical simulation for un-strengthened and strengthened surface are made to analyse the impact of tunnel construction on lines in the overlaying soil.
