Optimum design study on Leveling Variable Stiffness of Composite Foundation with Rammed Soil-cement Pile Zhenshuan Zhang1, Yu Deng2,a ,Wei Zhang3 and Desheng Ju1 1Hebei Academy of Building Research, Shijiazhuang, Hebei, 050021, China 2School of civil engineering, Hebei University of science and technology, Shijiazhuang, Hebei, 050018, China 3Department of Modern Science and Technology, Agricultural University of Hebei, Baoding, Hebei, 071001, China ady1234_0_0@163.com Keywords: Rammed soil-cement pile; Composite foundation; Settlement; Leveling variable stiffness; Optimum design Abstract.
The bearing capacity of foundation shallow soil is harsh demanded in engineering, whereas, the deep soil only meet the underlying stratum strength needs.
In engineering, both safety and economy should be considered, so the effect of structure rigid is considered in the optimum design of composite foundation with rammed soil-cement pile.
