Study On Jingang Highway Landfill Subgrade Construction Technology

Jingang highway has been passed through more landfill, how to carry out groundtreatment on the different venues foundation according to the depth of refuse, economic,construction conditions and other factors? How does construction waste applied to theroadbed construction process? based on the combination of relying engineering, This articleintends to carry out the following work:(1) Depth study on the physical characteristics of waste soil. Since municipal solid wastehas its particularity, before processing the garbage on foundation, we must understand thephysical and mechanical properties of municipal solid waste.(2) Study on the Landfill segment foundation approach. This article took four typicalsections ground treatment respectively. According to the different sections with differentground treatment methods carry out the observations, comparative study respectively.(3) Optimize the design of landfill expressway ground treatment methods. In this paper,improved TOPSIS multi-attribute decision making, will be extended to the intervalintuitionistic fuzzy sets, making it easier to reflect the realities of information and operational,the calculation is simple.(4) Study on the subgrade settlement law in highway landfill segment. Predict the roadembankment work through the ANSYS numerical simulation on Subgrade after settlement.And subgrade observations were analyzed to verify the simulation accuracy, and come to thesettlement of the law.
