Experimental Research And Numerical Analysis Of The Length Of Core Pile In Reinforced Mixing Pile

The reinforced mixing pile is a new kind of composite pile used in soft ground engineering which is composed of cement-soil ring and reinforced concrete core. It has a series of advantages compared with common cast-in-situ pile, such as, simple in construction, lower cost, higher bearing capacity, more reliable quality and lighter pollution. So it is a new type of pile with a bright future.In the bearing mechanism and theory research aspect, we have understood them better in the load capacity of the reinforced mixing pile. But as a composite pile, the affection on whole capacity , stress and strain of soil with different length of core pile have not known well. Through analyzing the date gotten from the located testing and the anti-computed results of MIDAS/GTS of finite element analysis, the result of numerical analysis have been contrasted and analyzed and a reasonable length of core pile is given. the author expected the thesis could supply some help to the further development of the reinforced mixing pile.
