River high slope two-stage reinforced soil flexible abutment composite structure and construction method thereof
The invention discloses a river high slope two-stage reinforced soil flexible abutment composite structure and a construction method thereof. The abutment composite structure comprises a lower-stage sheet-pile wall, a lower-stage reinforced soil structure, an upper-stage sheet-pile wall, an upper-stage reinforced soil structure and a road and bridge connecting structure. The lower-stage reinforced soil structure is arranged between the lower-stage sheet-pile wall and the upper-stage sheet-pile wall, and a wall surface reinforcing part is arranged between the lower-stage sheet-pile wall and the upper-stage sheet-pile wall; the lower-stage reinforced soil structure and the upper-stage reinforced soil structure are composed of a plurality of layers of gravel backfill soil and main reinforcement materials which are sequentially tamped and filled. And the road and bridge connecting structure is arranged at the top of the upper-stage reinforced soil structure. The sheet pile wall is used as the wall surface of the reinforced soil flexible bridge abutment, the rib materials and the wall surface form effective connection, it is guaranteed that the rib materials can give full play to the tensile deformation resisting effect of the rib materials, and the soil body is prevented from being subjected to tensile damage; and the sheet-pile wall surfaces of the two-stage reinforced soil bridge abutment are connected with each other, so that the stability of the sheet-pile wall is effectively ensured.
本发明公开了一种河道高边坡双级加筋土柔性桥台复合结构及其施工方法，所述桥台复合结构包括下级板桩墙、下级加筋土结构、上级板桩墙、上级加筋土结构、路桥连接结构；所述下级加筋土结构布设于所述下级板桩墙和所述上级板桩墙之间，所述下级板桩墙和所述上级板桩墙之间设置有墙面加固件；所述下级加筋土结构和所述上级加筋土结构由多层依次夯填的砂石回填土和主筋材组成；所述路桥连接结构布设于所述上级加筋土结构的顶部。本发明以板桩墙作为加筋土柔性桥台的墙面，筋材和墙面形成有效的连接，保证了筋材可以充分发挥其抗张拉变形的作用，避免土体发生张拉破坏；两级加筋土桥台的板桩墙墙面互相连接，有效保证了板桩墙的稳定性。
