The Study About Factors Analysis And Research Of Cantilever Pile In Excavation

With the vigorous development of China's construction industry, excavation is also developed to be larger and deeper. The support of Deep Excavation become more complex and more important. Cantilever pile is commonly used in Deep Excavation, it has good bracing performance and simple construction, so it has been widely used in excavation project. Therefore, deeply study of various factors on the piles'supporting effect, and research the working laws of supporting piles become more and more important, it has great practical significance and good economic efficiency.This article describes the overview of Foundation Engineering and the mechanism of supporting pile, at the conclusion of the several current common on support piles in domestic, and on the basis of the status quo of various factors' affection on the supporting piles. It proposes the paper's methodology and ideas.The paper use ANSYS software to establish the models of supporting piles, using a linear Drucker-Prager yield criterion for elastic-plastic model, a reasonable model of boundary conditions, analysis the supporting piles'diameter, modulus, shear strength of soil and other factors'performance on the supporting piles, analyze the degree of influence, at the same time, this paper summarizes the impaction of their laws. Finally, the paper compares the numerical results with the actual results, and analyses them, testes the feasibility of the numerical calculation method.Through the study of the paper, we can get some useful conclusions, they can provide some useful references for the similar designs and construction projects.
