Integral abutment bridge structure based on composite flexible piles and construction method thereof
The invention relates to the field of bridges, in particular to an integral abutment bridge structure based on composite flexible piles and a construction method thereof. The structure comprises an abutment horizontally arranged along a revetment, wherein the abutment is supported by the multiple vertical flexible piles embedded in the revetment, the flexible piles are composed of an ordinary concrete area embedded in the ground under the earth surface line and an ultra-high-performance fiber reinforced concrete composite material area connected to the ordinary concrete area, filling soil is stacked in the spaces between the abutment and the shoreside ground and between the flexible piles and the shoreside ground, approach slabs are laid on the filling soil, and the bear-abutment end of each approach slab is in lap joint with the end of a main beam arranged on the abutment. The structure aims to solve the problem that due to the fact that ordinary concrete piles are high in rigidity and poor in longitudinal-bridge-direction deformability and the tensile strength design value of ordinary concrete is small, concrete cracking can be caused easily under the external influence, or even fracture failure of the section of a pile foundation structure can be caused finally.
