Squeezed branch pile the nineties of the last century , the development of a special-shaped pile , its novel structure , bearing unique , with layered branches and bearing plate set , branch pile soil around the pile to mobilize layer carrying the potential to form a pile - soil interaction system to meet the project needs . Engineering practice : section piles branch pile and section pile compared to the same venue , etc. pile diameter , pile length , branch pile bearing capacity ratio of 1.5 to 2.5 times , the settlement section piles small deformation than 40 % to 70%. In this paper, a unique branch pile support plate structure , the effects from the construction , the bearing capacity calculated settlement discussed squeezed branch pile bearing deformation behavior , and by engineering examples , contrast explains squeezed branch high pile bearing capacity and low settlement reasons . Elastoplastic solution of 1 part of the construction effect , the combination of the spherical cavity expansion , focusing on \the disk pile pressure the actual situation , asked the impact of the frictional resistance of the branches and plates under the bottom side , to amend the relevant empirical formula and engineering instance calculated contrast ; 3 . subsidence calculation part , combined with friction Pile settlement characteristics and project operator cases contrast , from a single pile pile end the the plane additional stress the size of the angle , qualitative analysis of squeezed branch pile settlement deformation .
