欧洲研制的一种专利挡土墙系统自1969年投入使用以来已经用于建造了93万m~2的挡土墙,如图1所示。这种挡土墙由三部分组成。一是用普通混凝土现浇基础块,其宽度和厚度随挡土墙体的高度而定;二是扶壁式预制混凝土板,在挡土的一边带有混凝土支撑,同板整体地浇 A patented retaining wall system developed in Europe has been used to build a 930,000 m2 retaining wall since it was put into use in 1969, as shown in Figure 1. This retaining wall consists of three parts. One is the use of ordinary concrete cast-in-place foundation blocks whose width and thickness are determined by the height of the retaining wall body; the second is the buttress-style precast concrete slab, with concrete support on one side of the retaining soil, and the entire slab
