| Abstract: | This paper compares and analyses coordinately different failure mechanism and bearing capacity characteristics of composite foundation with rigid and flexible pile respectively, and factors which influence strength and rigidity of composite foundation, including the effective of pile length, replacement rate, stress ratio and deformation of pile soil, it discusses the practicability and economy of adopting rigid pile composite foundation on high-rise building (10 - 20 storeys high) built on soft foundation. According to the graphics of some static loading tests, it explains the strengthening effects of the rigid pile composite foundation and briefly introduces piling technology of rigid pile. |
