Bearing mechanism and estimation of bearing capacity of open-ended piles

通过室内试验和数值分析，研究了不同沉桩方式、不同桩身尺寸、不同地基条件下桩的承载机理。由于了解实际桩的承载能力是非常重要的，因此收集并调查了现场单桩载荷试验，以评估实际桩的承载能力。最后，提出了一种桩承载力随桩径变化的评价方法。

Laboratory experiments and numerical analyses of pile penetration with varying pile penetration methods, pile dimensions, ground conditions were conducted to investigate the bearing mechanism of a pile. Field loading tests on single piles were collected and investigated to evaluate the bearing capacity of actual piles, because it is important to know the bearing capacities of actual piles. Finally we proposed an evaluation method for pile bearing capacity as a function of pile diameter.
