摘要
由于某工程试桩直径大,试验场地有限,承载力确定困难,在比较常用桩基承载力检测方法后,确定采用自平衡法。阐述了自平衡试桩法试验原理和试验过程,通过试验得到了桩基竖向承载力、桩侧摩阻力和桩端阻力,可为同类地形、地质条件下大直径桩基的设计施工和检测提供参考。
Due to the large diameter of the test pileand the limited test site,it is difficult to determine the bearing capacity of a certain project.After comparing the detection methods for the bearing capacity of the commonly used pile foundation,the self-balanced method is adopted.The test principle and process of the self-balanced pile test method are elaborated,and the vertical bearing capacity of pile foundation,pile side friction and pile end resistance are obtained through the test,so as to provide reference for the design and construction and detection of large diameter pile foundation under similar topographic and geological conditions.
