The Research For The Technology of Inner struck Pile and The Coefficient of Pile Endpoint Resistance

摘要

This document introduces a kind of new technology including testing pile, making pile, measuring pile - the technology of the inner struck pile. The mechanism for the inner struck piles and small area method for testing pile was explained. The coefficient of the pile endpoint resistance was calculated in different depth with the finite element software and it's variation was analyzed with different parameters' variation (cohesion, friction angle, elastic modulus, Poisson's ratio). The result shows that the value of the coefficients of the pile endpoint resistance reduces with the rising of the value of depth and the value is affected by the size of the pile head and the soil parameters.
