| Abstract: | Application of the combined pile composite foundation to coastal soft soil areas is described.Based on in-situ stress measurements and three-dimensional numerical computation by FLAC3D,the stress development in piles and nearby soils is analyzed.Meanwhile,the mechanism of pile-soil interaction and the bearing ratios in piles and soils are analyzed in detail.The results show that the combined pile composite foundation can develop the properties of two kinds rigidity reinforced pile.It has obvious economical ... |
