Changchun City Composite Foundation Their Applicability And Energy Conservation And Emission Reduction Meaning Research

Composite foundation technology in our country civil engineering and construction of water conservancy projects have been widely applied, its theory and technology level with nearly 10 years of development, has become increasingly perfect in meet the foundation and the basis of the upper structure security, created more economic benefit. Sustainable development from the aspects of composite foundation for use, such as steel slag and fly ash industrial waste and construction waste as its raw material, make in materials to minimize the energy consumption on. In the world, and China's advocate low carbon environmental protection of the environment, have realistic significance of the energy conservation and emissions reduction.After thirty years of research, composite foundation design, calculation method, theoretical basis and construction technology gradually formed a complete system, is to produce a economic effect also has accepted identification, but in energy conservation and emission reduction of which are not very prominent. This paper studied area in changchun region are based on meet the applicability of composite foundation division of composite foundation conditions based on consumption based on BiaoZhunMei made that the amount of carbon emissions. For future design and construction technical progress more realistic significance.This paper first introduced the changchun region from natural geological survey, meteorology and hydrology landform, stratigraphic lithology, hydrogeological condition and several other aspects, in the study area for changchun geotechnical engineering geological division provide conditions. Through the past material and former people's experience and to collect borehole data of changchun region, according to landform features and combinations of lithology strata based on the research area, roughly divided into three areas:YiTong valley area, floodplains-order region and Taiwan. After the division of composite foundation according to provide reliable geology research.Second, introduces the changchun region in recent decades, the use of foundation forms in different periods induction and summarizes the foundation form and its developing process, and composite foundation in changchun and prospects the development of form, this paper introduces the main type of composite foundation and its theory. After the foundation of the applicability of the composite foundation provides theory basis.At last, from the Angle of energy conservation and emissions reduction demonstrates composite foundation and other forms of foundation, through comparing how much energy consumption and the amount of carbon emissions to measure the superiority of the composite foundation, based on consumption BiaoZhunMei as the unit of measure through different scales foundation forms of material composition, construction technology, economic cost, etc BiaoZhunMei by formula into consumption eventually change cipher out carbon emissions.In this paper, the main research results obtained as follows:1. Currently changchun building foundation types and existing problems;2. Through the previous engineering geology exploration material and its exploration of complete changchun city hole data housing construction engineering geological division;3. Through the engineering geological characteristics different partitions in changchun city building types summarized different foundation scheme and composite foundation; the applicability of partition scheme4. Demonstration composite foundation and other foundation in energy conservation and emission reduction plans is advantage.
