摘　　要：山西省临县至离石高速公路K70+170~K70+228段路基左侧原设计为衡重式路肩挡土墙,由于现场地面发生较大变化,不具备施做路肩墙条件,需变更设计。经现场重新勘察,对该段采用了桩板式挡土墙方案。桩板墙桩体高根据实际地形采用18m高和9m高两种方案,桩尺寸通过理正计算采用1.0m×1.5m,并在桩顶面以下2m处用锚定板拉接桩体。该处治方案施工后效果良好,可为陡坡黄土路堤防护工程设计提供参考。The original design for the left side of subgrade at the section of K70 ＋ 170 - K70 ＋228 of Linxian - Lishi Expressway in Shanxi province is a balance - weight - type retaining wall for road shoulder. Due to larger change of site floor, it is not with the condition of being taken as the wall of road shoulder and needs altered design. Through the reinvestigation on the site, the scheme for slab - pile retaining wall is adopted for this section. According to real topography, two schemes like height of 18m and 9m are adopted for the pile body of slab - pile wall, 1.0m ~ 1.5m is adopted for pile dimension by Lizheng calculation, and the pile body is connected by anchor plate at 2m under pile cape surface. After the construction, the treatment scheme is with good effect, thus providing reference for the engineering design of loess embankment protection with abrupt slope.
