Abstract


The Raw-soil structure,which is still used in our country,is one of the forms of the village and town building.The traditional Raw-soil structure has not generally provided fortifigation against earthquakes.The building materials is low in intensity and results in poor structure integrity.The is no corresponding standard to standardize when building. So the ability to resist the earthquake disaster is relatively bad.In this paper,the advantages and disadvantages of the Raw-soil structure are analyzed,the earthquakes damages that Raw-soil structure building undergo are described.The construction craft of Raw-soil structure are described,some problems concerning traditional building habits are discussed. Experimental studies on the physical properties and mechanics behavior of the material on Raw-soil structure.The Raw-soil materials, which is used to make adobe and traditional adobe house in Xinjiang, is mixed with coarse sand and straw . Reference to concrete test standards, using the traditional manual process produced four kinds of Row- soil and two kinds of modified soil materials compression test block. Through the comparative analysis of block compression tests.its compressive strenth and deformation capacity are studied. Edge length of 100mm cube test results show that both coarse sand and straw improved cubics’strenth and ultimat displacement, at the same time ,a appropriate additives ratios is suggested。The use of large-scale finite element software ANSYS10.0, under the vertical load of the elastic-plastic analysis of a block。At the same time, with reference to the standard test of masonry structure, through the masonry of the Raw- soil compressive resistance test analysis, to study the compressive strength and deformability.The researches will contribute to the development of traditional adobe house in xinjiang,especially the raw- soil selection and standards draft。
