摘要
Abstract
Curved spiral pile is a new type of anti-pull pile with fast construction speed,low environmental pollution and high pile quality.It is widely used in highway,construction and other foundation projects.It can increase the indirect contact surface of pile and soil,increase the friction of pile side and enhance the uplift bearing capacity of pile.In order to further understand the pull-out bearing mechanism of spiral pile,the indoor model test method is adopted to carry out simulation tests on curved spiral piles with different spiral width and thickness.The uplift displacement,axial force,lateral friction and soil pressure around the pile are monitored respectively under different pull-out loads.Furthermore,the influence of spiral width and spiral thickness on the bearing mechanism of pile under uplift load is analyzed,and the conclusion that spiral width is the main influence factor of uplift bearing mechanism is summarized in order to provide reference for the scientific application of curved spiral pile in foundation engineering.关键词
