| Abstract: | On the base of the theoretical analysis,experiment results and numerical simulations,a new method for calculating the settlement of composite pile foundation, modified simplified stress method, is put forwarded,which is applied to analyze three cases.According to the deformation characteristic of composite pile foundation,this method takes the compression of soil between piles into account.The comparison between calculated results and measured data shows that the new method enjoys merits of simplified calculation,clear physical concept and certain precision.It is suggested that the simplified method is convenient to analyze the practical cases. |
