1 概述 加筋土挡墙是由墙面板、拉筋和填筑料组成的加筋土体以承受土侧压力的挡墙。在加筋土结构中,由填土自重力产生的土压力作用于墙面板,通过墙面板上的拉筋连接件将此土压力传给拉筋,企图将拉筋从土中拉出,即依靠填料与拉筋之间的摩擦力,平衡墙面板所受的水平土压力,并以这一结构抵抗拉筋以外区域填料土压力的挡墙结构形式。加筋土挡墙的主要优点是施工简便、造价低廉、少占土地,造形美观。
1 Overview Reinforced earth retaining wall is composed of wall panels, reinforcement and filling materials composed of reinforced soil to withstand pressure on the soil side wall. In the reinforced earth structure, the earth pressure generated by filling the soil from the gravity acts on the wall panel, and the earth pressure is transmitted to the stretching rib through the tie bar connection on the wall panel in an attempt to pull the stretching rib out of the soil, that is, By means of the friction between the filler and the tensioning bar, the horizontal earth pressure on the wall slab is balanced and the retaining wall structure which resists the pressure of the earth filling material in the region other than the tensile bar is balanced. The main advantage of reinforced earth retaining wall is the construction is simple, low cost, less land, beautiful appearance.
