Zusammenfassung: | 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- |
