The Stess-proliferation of the Theory of Composite Foundation Considered and Application in Engineering

For composite foundation theory has been widely used in the treatment of soft foundation engineering practice status quo , while reinforcing the effective length of pile composite foundation theory is that one of the important issues to be considered . In this paper, plus solid load transfer law and stress diffusion theory perspective , the application of elastic half-space at any point in the body additional stress Bosinessq solution , find effective length formulas , combined with engineering examples introduce effective length in engineering applications .
