我国铁路首次采用层厚控制材解决路堤边坡溜坍的试验工作,由专业设计院与西安铁路局西乡工务段共同进行,于1月8日在阳安线210公里附近路堤中铺设完毕,长40米。层厚控制材为高密度聚乙烯塑料网格,分层辅设在路堤中。由于网格与路堤的散粒填料产生摩阻力,使整个路堤强度增加。此次试验是针对阳安线裂隙土地带的边坡溜坍病害,在路堤中铺设塑料网格,以此作为填料的加筋材,从而使边坡得到补强,阻止溜坍。
For the first time, China’s railways used layer thickness control materials to solve the experiment of embankment slope slips, which was jointly conducted by the Professional Design Institute and Xi’an Railway Bureau Xixiang Public Works Section. On January 8, it was laid in the embankment near 210 km of Yang’an Line, 40 meters long. Layer thickness control material for high-density polyethylene plastic grid, layered auxiliary embankment. As the grid and the embankment of the particulate filler friction resistance, so that the strength of the entire embankment increased. The test is aimed at the slope of the Yangan Xianchuan slipped landslide disease, laid in the embankment plastic mesh, as a filler of reinforced material, so that the slope is strengthened, to prevent slipped.
