近年来,预应力锚索技术得到了广泛的应用。其原理是通过锚索、注浆液与深层稳定岩体的胶合作用,由锚索传递张拉力,牵制表层松散层,使边坡松散层与稳定地层连接成一个坚固稳定体,从而达到加固边坡的目的。工程概况福建永宁高速公路很多路段为顺层高边坡,山体呈侏罗系泥岩、砂岩互层,极易风化。路堑边坡最高处达32m,路堑开挖极易导
In recent years, prestressed anchor cable technology has been widely used. The principle is that the anchorage cable, the grouting fluid and the deep stable rock mass are glued to each other. The tensile force is transmitted by the anchor cable, and the loose layer in the surface is restrained, so that the loose layer in the slope is connected with the stable formation to form a solid and stable body, The purpose of the slope. Project Overview Yongning Expressway in Fujian many sections of the slope along the bedding, the mountain Jurassic mudstone, sandstone interbedded, easily weathered. Cutting slope up to 32m, cutting easily lead
