| Abstract: | This paper describes the design method of prestressed pipe pile composite foundation on the expressway soft ground treatment. For the composition characteristics and deformation properties for prestressed pipe pile composite foundation, the ＂secondary composite＂ method of calculating the total reinforcement area foundation settlement is proposed which can check the bearing capacity of compos ite foundation based on a combination of pile. |
