Highway bridge reinforced soil flexible abutment structure and construction method thereof
The invention discloses a highway bridge reinforced soil flexible bridge abutment structure and a construction method thereof. The highway bridge reinforced soil flexible bridge abutment structure comprises a bridge span structure, a bridge head comprehensive approach road, a pavement structure, a base and a reinforced soil bridge abutment body. When the distance between the base and the abutment wall panel is far, a bearing area front side panel and a bearing area rear side panel are arranged in a filler area of the reinforced soil abutment body, and the filler area of the reinforced soil abutment body is divided into an abutment backfill soil area, a bearing area and an abutment backfill soil area; the abutment backfill soil area adjacent to the abutment wall panel is filled with pre-compacted low-strength filler, the abutment backfill soil area far away from the abutment wall panel is filled with field compacted low-strength filler, and the bearing area is located under the base and filled with field compacted high-strength filler; when the distance between the base and the bridge abutment wall panel is small, a bearing area rear side panel is arranged in the filler area of the reinforced soil bridge abutment body, the filler area of the reinforced soil bridge abutment body is divided into the bearing area and a bridge abutment backfill soil area, the bearing area is located under the base and filled with pre-compacted high-strength filler, and the bearing area is located under the base and filled with pre-compacted high-strength filler. And the backfill soil area of the bridge abutment is filled with low-strength filler compacted on site. Filling materials with different strengths are adopted in different areas of the bridge abutment, the strengths of the different filling materials are brought into full play, meanwhile, backfilling close to one side of the bridge abutment wall panel adopts assembly type construction, and the problem of horizontal deformation of the bridge abutment wall panel caused by on-site compaction is solved.
本发明公开了一种公路桥梁加筋土柔性桥台结构及其施工方法，包括桥跨结构、桥头综合引道、路面结构、基座和加筋土桥台本体；当基座与桥台墙面板之间的距离较远时，加筋土桥台本体的填料区内设有承载区前侧面板和承载区后侧面板，将加筋土桥台本体的填料区分为桥台回填土区、承载区和桥台回填土区，邻近桥台墙面板的桥台回填土区填充预先压实的低强度填料，远离桥台墙面板的桥台回填土区填充现场压实的低强度填料，承载区位于基座正下方且填充现场压实的高强度填料；当基座与桥台墙面板之间的距离较近时，加筋土桥台本体的填料区内设有承载区后侧面板，将加筋土桥台本体的填料区分为承载区和桥台回填土区，承载区位于基座正下方且填充预先压实的高强度填料，桥台回填土区填充现场压实的低强度填料。桥台的不同区域采用不同强度的填料，充分发挥不同填料的强度，同时邻近桥台墙面板一侧的回填采用装配式施工，解决了现场压实导致桥台墙面板水平变形的问题。
