ZHI Bin, HAN Xiao-lei, QI Ming-jun. Determination of compaction model of loess surrounding the compaction pile in loess region[J]. 2006, 27(7期 刊出日).DOI:
The deficiency of Duncan-Chang model in analyzing the stress of the loess surrounding the compaction pile is pointed out. Based on this analysis
the laboratory soil test is conducted and the compaction principle of the loess surrounding the pile in the loess region is analyzed; the above analysis leads to a conclusion that modulus of deformation accords with Duncan-Chang model before the loess surrounding the compaction pile failing and to be determined by modulus of compressibility of remolded sample compression test and suggested coefficient ? after failed. Then
a loess compaction model is suggested and verified through an example. The model sets a solid foundation for the future stress analysis of the loess surrounding the pile and has reference value to perfecting design theory of the compaction pile.
