Abstract

The invention provides a road peat soil soft foundation comprehensive treatment method. The road peat soil soft foundation comprehensive treatment method comprises the steps that a work platform for treatment of a soft foundation is built; on the work platform, pre-pressing objects are loaded on the soft foundation for overload pre-pressing construction; and in the pre-pressing period, whether thesoft foundation meets the design requirement or not is checked. According to the road peat soil soft foundation comprehensive treatment method, the pre-pressing objects are used for overload pre-pressing treatment of the soft foundation, construction is conducted by adoption of the subarea and classified construction mode, the sedimentation rate of the pre-pressing objects is detected in the pre-pressing period, and the pre-pressing objects are unloaded after the sedimentation rate meets the design requirement. Through the method, the problems that deep and thick peat soil serves as a road bed, so that the bearing capacity is insufficient and sedimentation is uneven are effectively solved, before main consolidation sedimentation and partial residual sedimentation are completed, the soft foundation consolidation cycle is shortened, and the probabilities of large uneven sedimentation difference and sedimentation rate sudden change are decreased. Local materials are used for the pre-pressing objects, under the premise that the engineering quality is ensured, the construction efficiency is improved, and the overall construction cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a comprehensive treatment method for road peat soil soft foundation. Background technique [0002] At present, in some road construction, soft soil foundations are often encountered, and the peat soil and silty clay in the soft soil foundation have the characteristics of large void ratio, high water content, high compressibility, high organic matter content and low shear strength, etc. features. For the foundation treatment of this large-scale peat soil, the traditional design does not fully consider the non-uniformity of the soil layer thickness of the peat soil and the characteristics of large changes. The single treatment method leads to high energy consumption and high cost of construction; Long consolidation period of peat soil, uneven settlement, sudden change in consolidation rate and other factors lead to uneven subsidence of subgrade and pavement cracking afte...
