Buttress plate and unloading plate combined retaining wall and internal force calculation method thereof
The invention relates to the field of slope support engineering, and provides a buttress plate and unloading plate combined retaining wall and an internal force calculation method thereof.The buttress plate and unloading plate combined retaining wall comprises a bottom plate, a first vertical plate, a second vertical plate, a buttress plate and an unloading plate which are all of a reinforced concrete structure; backfill is filled behind the retaining wall structure; the first vertical plate is arranged on the bottom plate, the second vertical plate is arranged over the first vertical plate, and the first vertical plate and the second vertical plate are in lap joint with the buttress plate. The unloading plate is arranged between the first vertical plate and the second vertical plate and forms an unloading pressure reduction platform; the unloading plate is in lap joint with the adjacent buttress plate and the first vertical plate and/or the second vertical plate. Horizontal soil pressure acting on the retaining wall is effectively reduced by combining the buttress plate and the unloading plate, and structural internal force, including shearing force and bending moment, on the retaining wall is reduced; horizontal displacement of the retaining wall is reduced; the section size of the retaining wall structure is reduced, and meanwhile engineering construction difficulty and cost are reduced.
本发明涉及边坡支护工程领域，提供一种扶壁板与卸荷板组合式挡土墙及其内力计算方法，包括均为钢筋混凝土结构的底板、第一立板、第二立板、扶壁板和卸荷板；在挡土墙结构后方充填有回填料；所述第一立板设置在底板上，所述第二立板设置在第一立板的正上方，所述第一立板、第二立板与扶壁板搭接；所述卸荷板设置在所述第一立板和第二立板之间，卸荷板形成卸荷减压平台；所述卸荷板与相邻的扶壁板以及第一立板和/或第二立板搭接。通过将扶壁板+卸荷板组合有效减小挡土墙上作用的水平土压力，减小挡土墙上结构内力，包括剪力和弯矩；减小挡土墙水平位移；减小挡土墙结构截面尺寸，同时降低工程施工难度和成本的。
