Analysis Of Force And Settlement The Concrete Thin-Wall Pipe Pile Composit Foundation

Cast-in-situ concrete thin-wall pipe pile(PCC pile) is a new type of pipe pile,it hasadvantages of prestressed pipe pile,buffeting pipe-sunk piles and buffeting mould-sunk cutoffwall. And be in charge of the pole technology for the thin-wall making use of now to depositconcreterationally,effectiveextensionofmakingisputintouse,theresearchbearingtheweightof a force to the person certainly needs extremely. On the basis the main body of a book isstudied in drawing whose prehominid's, calculating and optimizing design by the fact that thescene tests that the land base studying pole treatment is soft with ANSYS simulation analysis,toconcrete thin-wall pipe pile compost foundation thorough research and investigation anddiscussion.Simulation carryingout a pole when soil is analytical , often adopt the Goodman element tocarry out a contact surface in Finite Element Method. By introducing non-linear behaviors(concrete behaviors, soil elastic and plastic behaviors and several classical methods ofinterfaceelement) ,and recur to ANSYS finite element currency software, and based on APDLlanguageprogrammeform,theauthormadegreat effortonthemechanics characteristicmodelingofpilefoundationbytheverticalandhorizontaldynamicltoads.Thorough fact project,Yanhai road Tangshan high way,it's analysis the concrete thin-wallpipe pile compost foundation's force and settlement under the mollisol ground,get the followingconclution:1.
