Large Diameter Bored Prestressed Concrete Hollow Pile Mechanical Property Of Simulation Analysis

On the basis of construction technique of large diameter bored hollow pile of prestressing force concrete, through the program of MARC, this paper analyses the pile vertical bearing capacity under different lengths, diameters and strength parameters of mediators as well as the inner force and displacement under lateral and combined loads, giving the criterion of rigid pile and flexible pile. With elastic theory, the paper establishes the inner force calculating formula under eccentric load. This research findings will set a firm theoretical foundation for its widely application.
