加劲水泥土地下连续墙中水泥土强度分析

对加劲水泥土地下连续墙的工作机理进行了分析,指出在加劲水泥土地下连续墙设计中水泥土必须具有足够的强度。型钢间的水泥土不仅需要满足抗剪强度的要求,还应满足水平方向斜截面强度的要求。水泥土对墙身竖向抗弯刚度的贡献虽然可忽略,但应有足够的抗压强度以保证其止水性,同时水泥土还应对型钢具有足够的侧向约束并保持完整性以维持型钢的整体稳定性。

Analysis of strength of soil-cement in reinforced soil-cement mixing diaphragm wall

The working mechanism of reinforced soil-cement mixing diaphragm wall has been analyzed.It is pointed out that the strength of soil-cement must be enough in the reinforced soil-cement mixing diaphragm wall.The strength of soil-cement between the shaped steels must be enough not only to load the shear stress,but also to load inclined section stress along the level.Although the contribution of soil-cement to vertical bending rigidity of the wall is too little to neglect,the compression strength of soil-cement must be enough to be kept integrity and water stop.On the other hand,the side restriction of soil-cement to shaped steels must be strong enough and be kept integrity to keep integral stability of shaped steels.
