| If we build a high-grade highways in flat area, the right foundation processing scheme influence construction and investment. It is a problem to choose right scheme that technology is reliable and cost is reasonable. The passage introduce a model that fuzzy similarity priority ratio soft foundation construction base on analytic hierarchy process, this model will supply a smart and scientific method to solve soft foundation of highway.The people lack theoretical research to embankment under repeated traffic load, deformation and dynamic response of roadbed strength at home and abroad. The passage supply a scientific basis that depth and scope of subgrade dynamic stress overload and embankment height change on the transmission by computational analysis.The passage build a model that embankment right height under the action of traffic load long time to solve the problem, such as high embankment take more land, the cost of soft foundation construction is expensive, the quality is uncontrolled and driving comfort is poor.The passage supply a theoretical foundation to low-embankment design according to numerical analysis of research results and the characteristics of low embankment. These theoretical foundation is build base on follow:Ⅰ. The research of embankment height influencing factors, reasonable reduce embankment height.Ⅱ. Take full advantage of overlying crust engineering characteristic to improve base course of pavement severity, improve pavement structure density and adopt other measures. |
