| Abstract: | Some research circumstances about rigid pile composite-foundation are introduced, and the bearing mechanism of the composite-foundation is pointed out.The varying regularity of the stress ratio and the settlement under all sorts of influence factors are studied.The influence factors include the cushion thickness,cushion modulus,pile length,pile spacing,and modulus of soil between piles.The problem which design parameters should be selected within rational range and problems which need further research are presented. |
| Keywords: | rigid pile composite-foundation stress ratio of pile-soil proportion of load contribution |
