Comprehensive treatment method for solving bridgehead bumping hazard of low roadbed in soft soil area
The invention belongs to the technical field of geotechnical engineering, and discloses a comprehensive treatment method for solving bridgehead bumping hazards of a low roadbed in a soft soil area. Firstly, a treatment area is determined, a pavement structure layer in the area is cleaned, and pile hole positions are arranged; drilling and soil taking are carried out, and the roadbed soil and the foundation soil are made into flow-state solidified soil; foundation section flow state solidified soil is poured into the pile hole, after the core pile is inserted, the roadbed section flow state solidified soil is poured into the pile hole till the pile hole is filled, and a solidified soil pouring composite pile is formed; and finally, the honeycomb-shaped pavement reinforced panel and the asphalt mixture are laid until the pavement is flush with the bridge floor. The foundation, the roadbed and the pavement structure layer are considered as a whole, the foundation is strengthened through the solidified soil cast-in-place piles, the roadbed is strengthened through the solidified soil cast-in-place composite piles, and then the solidified soil cast-in-place composite piles are connected with the pavement strengthening structure to form the whole strengthening structure, vertical deformation of the foundation and the roadbed is controlled fundamentally, and the bumping disease at the bridgehead is solved.
本发明属于岩土工程技术领域，公开了一种解决软土地区低路基桥头跳车危害的综合治理方法。首先确定治理区域，对该区域内的路面结构层进行清理，并布置桩孔孔位；然后钻孔取土，将路基土和地基土分别制作成流态固化土；再将地基段流态固化土灌注到桩孔中，插入芯桩后将路基段流态固化土灌注到桩孔中直至填满，形成固化土灌注复合桩；最后铺设蜂窝状路面强化面板和沥青混合料，直至路面与桥面平齐。本发明将地基、路基和路面结构层作为整体考虑，通过固化土灌注桩强化地基，固化土灌注复合桩强化路基，再与路面强化结构之间连接形成整体强化结构，从根本上控制地基和路基的竖向变形，解决桥头跳车病害。
