Abstract

The invention provides a peat soil soft soil roadbed strength improving method. The peat soil soft soil roadbed strength improving method comprises the steps that a tree is cut on the spot, and segmented cutting is conducted; cut and machined trunk sections are transported to a storage yard in a unified manner, and centralized stacking and storage are conducted; peat soil soft foundation surface sundries are removed, and leveling is conducted on the peat soil soft foundation surface; the trunk sections are evenly laid on the surface of the peat soil soft foundation, and a trunk strengthening layer is formed; a gravel cushion layer is laid on the trunk strengthening layer; a geotechnical cloth isolation layer is arranged above the gravel cushion layer; and filling of a roadbed first layer is conducted, and a vibration road roller is adopted for compaction, and stability checking calculation is conducted. The wood taken on the spot has the characteristic of good rigidity, the problems that geotextile is free of rigidity, and sedimentation cannot be reduced are solved, the geotextile and the wood property can be complemented, the purposes of strength improving and sedimentation reducing are achieved, the wood is taken on the spot, and cost is low. Meanwhile, the method can replace an existing common treatment method, and the time cost and the construction cost are saved.

Description

technical field [0001] The invention relates to the technical field of soft soil roadbed construction, in particular to a method for improving the strength of peat soil soft soil roadbed. Background technique [0002] At present, peat soil is a type of soft soil, and its origin determines that this type of soil is generally distributed in areas with relatively dense vegetation such as coastal areas, lagoons, and drowned valleys, and has high moisture content, high compressibility, low strength, and high thixotropy. , high sensitivity and other remarkable features, often have problems such as insufficient bearing capacity and large deformation, which are extremely unfavorable to the construction of infrastructure such as roads, railways, ports, dams, and municipal facilities. Therefore, before infrastructure construction in peat soil areas, corresponding soft foundation treatment is generally required. At present, the main treatment methods are overload preloading, gravel pi...
