Arch bridge foundation on deep and thick round gravel bed underlying limestone foundation, and construction method of arch bridge foundation
The invention discloses an arch bridge foundation on a deep and thick round gravel bed underlying limestone foundation. The arch bridge foundation comprises a shaft type secant pile wall, a crown beam, ring-shaped waist beams, a latticed pile wall foundation, a bottom plate, a skewback, compacted fill, and a cover plate, wherein except the compacted fill, all the components are cast-in-place reinforced concrete members; and a pit enclosure structure is formed by the shaft type secant pile wall, the crown beam and the ring-shaped waist beams, so as to provide a construction space and environment for the construction of the bottom plate, the skewback, the compact fill and the cover plate, and to serve as a side wall of the arch bridge foundation. Based on the structure of the arch bridge foundation, the invention further provides a corresponding construction method. The arch bridge foundation and the construction method thereof disclosed by the invention have the advantages that the archbridge foundation achieves high stabilities against overturning and sliding, and large horizontal and vertical bearing capacities; and through the construction method, rapid construction in the deepand thick round gravel bed underlying limestone foundation can be achieved, the construction difficulties and cost of the traditional long-span arch bridge foundation can be greatly reduced, and a construction period of the traditional long-span arch bridge foundation can be greatly shortened.
本发明公开了一种深厚圆砾层下伏灰岩地基拱桥基础，包括井筒式咬合桩墙、冠梁、环形腰梁、格形桩墙基础、底板、拱座、压实填土和盖板，除压实填土外均为现浇钢筋混凝土构件，其中由井筒式咬合桩墙、冠梁、环形腰梁组成基坑围护结构，为底板、拱座、压实填土和盖板的施工提供施工空间和环境，并兼做拱桥基础的侧墙。据此，发明人还建立了相应施工方法。本发明的拱桥基础抗倾覆和抗滑移稳定性好、水平及竖向承载力高，该施工方法可在深厚圆砾层下伏灰岩地基中快速施工并显著减少传统大跨度拱桥基础施工难度、工期及费用。
