摘　　要：包西铁路在柳树店段受地形及既有建筑物的影响,改线后遇见黄土高边坡挖方工程,采用明洞通过。为避免施工过程中边坡塌方及解决明洞的偏压问题,采用路堑桩板墙与明洞工程相结合的方案,用桩板墙工程代替明洞工程抵抗左侧山体变形而形成的偏压,保证了施工过程边坡的稳定。The opencut tunnel with high side slope of loess was adopted in Liushudian section of Baotou-Xi'an Railway.To avoid side slope collapse during construction and to solve the problem of eccentric compression on the opencut tunnel,the scheme of sheet pile wall on the cutting in combination with the opencut tunnel was utilized.It is considered that instead of the opencut tunnel,the sheet pile wall can resist the eccentric compression caused by the deformation of the slope mass on the left side,so the stability of side slope during construction can be guaranteed.
