Research On Load-bearing Characteristics Of Cement-flyash-gravel Composite Foundation

Now, with the expansion of construction scale of civil engineering, the treatment of the foundation has become a key concern of Engineers. Cement-flyash-gravel pile composite foundation with good social and economic benefits, has been more and more widely used in engineering. With the research aim of applied in tall buildings, the dissertation systematically studied, combining the yinchuan area concrete engineering examples.1. In this paper based on cement-flyash-gravel pile composite foundation Theory, Emphatically analyzes of the engineering characteristics, reinforcement mechanism, under vertical load of trait, and the theoretical formula of bearing capacity.2. Analysis and research of this engineering field test in yinchuan area, comprehensive analysis and discussion of this engineering general situation, field test scheme, and field test results.3. Using the finite element numerical simulation, with this engineering practice be united in wedlock, the reasonable choose of parameters, analysis and discussion of establish the model.A combination of The practical engineering and Finite element calculation, Influencing factors of bearing characteristics of it have been analyzed, Thus to get suitable for Yinchuan area the bearing performance of foundation handle, and for Summary of Analysis, to provide reference of cement-flyash-gravel pile composite foundation engineering design.
