Integral bridge abutment structure for controlling subsidence of abutment backfill and construction method of integral bridge abutment structure
The invention relates to improvement of an integral bridge abutment structure in bridge engineering, in particular to an integral bridge abutment structure for controlling subsidence of abutment backfill and a construction method of the integral abutment structure. The integral bridge abutment structure comprises a concrete pile foundation, a bridge abutment and an approach slab connected with the bridge abutment, wherein a corrugated metal plate is fixed to the rear surface layer of the bridge abutment, a plurality of layers of foam plates are laid upwards in the vertical direction between the approach slab and compacted abutment backfill and tightly attached to the corrugated metal plate, and a filling soil layer with the thickness of 20-30 cm is laid on each layer of foam plate. And the filling height of the foam plates and the filling layer is consistent with the height of the bridge abutment. According to the novel structure, the horizontal deformation capacity of the bridge under the action of temperature and earthquake load is greatly improved while settlement of the abutment backfill is effectively controlled.
本发明涉及桥梁工程中整体式桥台结构的改进，具体是一种控制台后填土沉降的整体式桥台结构及其施工方法。本发明的整体式桥台结构，包括混凝土桩基、桥台、与桥台连接的引道板，在桥台后表层固定有波形金属板，在引道板与压实的台后填土间紧贴波形金属板沿铅垂方向向上铺设有若干层泡沫板，每层泡沫板的上面铺设有20—30㎝厚度的填土层，所述泡沫板与填土层的填筑高度与桥台高度一致。本发明的新型结构在有效控制台后填土沉降的同时，极大地提高了桥梁因受到温度、地震荷载作用下水平变形能力。
