Analysis the Bearing Force Characteristic of the New Cast-in-Place Concrete Pile with Half-Screwed

Abstract

Half-screwed pile is a new kind of pile. Because of the unique design of variable cross-section, bearing principle and working traits are much more complex than the traditional linear pile. The vertical load transmission mechanism thoroughly is analyzed about half-screwed pile based on the static load experiment results. Researching its work performance, load transfer mechanism, the force mode, has important theoretical and practical significance.
