Abstract


In the recent several dozens of years, composite foundation using and developing rapidly in our country, many kinds of composite foundation Processing methods appears in abundance. Because the CFG pile composite foundation has the project characteristics of the applicable scope is broad, the enhancing scope of bearing capacity to be big and the adjustment is strong, subsidence slightly after project, the quality of construction can be guaranteed easily, the economic efficiency is good project and so on. It is used in projects widely. China is a country with large Permafrost. The structures which are constructed in Permafrost region are influenced by the instability of frozen soil on thermodynamics. The application of CFG pile in permafrost is no study, so the research of CFG pile in permafrost has very important practical significance. As the frozen soil has a strong sensitivity to temperature, the distribution of temperature field in permafrost is the premise, so is the top priority.Based on the pile、the basic theory and application of frozen comprehensive analysis this paper do the following aspects work;1、According to the characteristics of CFG pile and the permafrost, the experimental area is established near the Yisui road K44+515-K44+525, and test the temperature of the permafrost;2、Under the principle of heat transfer with phase change, body heat flux, heat, and the thermal parameters of permafrost and other factors, the pile-soil finite element model is established;3、Finite element model will be calculated and compared experimental area measured, analyzed the impact of fly ash concrete hydration heat to the temperature field, obtained CFG pile thermal disturbance core of permafrost;4、Analysis the different mold temperature in permafrost temperature field, reached a reasonable temperature into the mold.
