Gansu Loess Classification Of Zoning And Road Divisions

In this article, the climate index of suhgrade and pavement work state such as quantity of heat. moisture content and their equilibrium condition arc analyzed by way of the research of the natural geography environment in the ioess area. The climate and the hydrology condition iii Gaiisu Pro\ince loes area are analyzed and summed up comparatively overall. On the basis of analysis to the development history, principle and index of climatic zoning for high\vay in our country, the leading factors and the marks of bess zonin in Gansu Province and the third classification of climatic zoning for highway are studied, and the scheme of the third classification of climatic zoning for highway is putted forward. Characteristic and index of the third classification in Gansu Province bess area and influences of natural condition of various third classification to the highway engineering are briefly concluded and analyzed by way of analysis to the hydrology geology condition and bess specified property in Gansu Province bess area. Serving as the purpose with the third classificatioii he applications in the highway engineering, specific properties of building a highway with bess and the engineering measures are summed up and are analyzed. Combinina with the research achievements before, the design parameters of subgrade and pavement to be fit for natural condition of this area and pavement structure recommendation scheme is putted forward, and supplies to consult to use.
