Background technology
At present, under the background of urbanization fast development,, must develop green building, change the pattern of construction industry high investment, high flow rate, high pollution, poor efficiency as the construction industry of the mass consumption energy and resource.The villages and small towns building accounts for national floor area of building more than 50%; under the situation that the contradiction of resource, environment and development becomes increasingly conspicuous; the pressure of minimizing to resource, environment of will trying one's best is built in villages and small towns; therefore; greatly develop villages and small towns green building research and practice, to New Countryside Construction, build the characteristic cities and towns, reduce resource consumption, preserve the ecological environment significant.
Earth building has long history abroad, and in today of people's common concern ecological crisis, energy dilemma, environmental pollution, earth building becomes the focus that the various countries scholar pays close attention to research again.The various countries researchist carries out a large amount of experimental studies according to the soil property situation of this country, explores the correlative factor that influences earth building function and shock resistance, has proposed corresponding codes and standards.Developed country mainly concentrates on three aspects around the research of earth building unfolded: the one, how to improve immature soil intensity, and be reinforcement material mainly to add cement for this reason, and research new soil properties-correcting agent; The 2nd, exploitation earth building special construction apparatus improves operating efficiency; The 3rd, the relation of research construction technology and immature soil body of wall physical and mechanical property influences mechanism etc. such as compacted density, native composition and granule content to immature soil body of wall thermal conductivity index.The above-mentioned technological contribution of developed country has effectively improved intensity, weather resistance, operating efficiency and the anti-seismic performance of earth building.
Domestic research work about earth building mainly concentrates on two aspects: the one, how to improve the anti-seismic performance of immature soil intensity and earth building, be reinforcement material mainly for this reason, and improve immature soil body of wall globality by reinforcement (woven wire, farm crop and straw) with interpolation cement, lime, flyash; The 2nd, the relation of research construction technology and immature soil body of wall physical and mechanical property influences mechanism etc. such as compacted density, native composition and granule content, water ratio to immature soil strength of wall body and weather resistance.The research thinking is with basic identical abroad, and the degree of depth of research work has been compared certain gap with systematicness with external advanced level, is especially also having a lot of work to do aspect raising operating efficiency and the formulation of rules standard.
