By means of field test for the pile of 15 meters length and MARC finite element analysis, this paper studies the bearing mechanism of the reinforced mixing pile, analyzes the law of load transfer and the percentage about cement-soil ring and reinforced concrete core under vertical load, analyzes the change law and interactive behavior about the pile's surface bearing and end bearing. In the end an experiential equation that can be used in Tianjin area to estimate the bearing capacity of single pile is proposed on the basis of test researches and finite element analysis.
