毛陕高速高填路堤桩板墙支挡工程的设计与施工

Design and Construction of Sheet-pile Wall for High Embankment in Mao-Shan Highway

结合毛陕高速淇水村加水冷却区路堤桩板墙支挡工程实例,介绍了高速公路建设过程中地形受限地段高填路堤桩板墙加固技术,针对上述加固方法进行了路堤边坡的稳定性分析计算及其加固工程设计,并对边坡加固工程施工工序与原则进行了探讨。成功的工程实践表明,高填路堤边坡支挡方案中,桩板墙在保证边坡安全系数的同时能够降低工程投资,值得在同类工程中借鉴。

Based on the engineering practice of sheet-pile wall for reinforce the high embankment in Qishui village water cooling district of Mao-Shan Highway,the paper presents the technique using sheet-pile wall to reinforce high embankment in limited terrain.In line with the embankment reinforcement technique,the stability of embankment was analyzed and calculated,and the designs for embankment reinforcement were made according.The process and principle for sheet-pile wall are also discussed in the paper.Successful engineering practice shows that in many programs of retaining high embankment slope,sheet-pile wall not only ensure the safety factor but also reduce the engineering investment,the practice is worth to learn for similar projects.
