Abstract
The invention relates to a novel foundation and road bed treatment mode, and in particular relates to a similarly arch reinforcement treatment method by adopting bagged gravels and sandy soil on the spot. According to the method, the bagged gravels and the sandy soil are used as raw materials; and a similarly arch mode is used for foundation reinforcement treatment and is applied to road bed foundations as well as medium and light building structure engineering. A woven bag constricts a soil body in a bag, so that a non-sticky soil body is converted into similarly sticky soil body, and the shearing strength of the soil body is improved. During foundation treatment, an upper load is transmitted to the deep part of the foundation according to a mechanical transmission characteristic of an arch structure, so that shearing stress is reduced, and non-treated soil is encircled. The foundation is treated by adopting rough particles with relatively high water permeability, so that the water permeability of the foundation soil is guaranteed, and the freezing expansion resistance of the foundation or the road bed in a cold place in the north is improved; and moreover, due to constriction of the soil bag to the soil body, a phenomenon of liquefaction of fine sand and powdered sand in an earthquake is effectively avoided.
