摘要
通过荷载传递法对天兴洲大桥超长桩基承载特性的影响因素进行分析。从桩长、桩径、桩端土层等效刚度对桩Q^S曲线的影响;桩端阻力分担比与桩长的关系;桩长径比对桩端阻力分担比的影响几个方面分析了超长桩承载机理的影响因素。分析结果表明,这些因素对于超长桩基的承载特性有着重大的影响。
Influencing factors of bearing behavior for Tianxingzhou bridge super-long single pile by using load transfer method.The influence factors of bearing mechanism of super long single pile were analyzed from some aspects,such as the influence of pile length,pile diameter,equivalent stiffness of pile-side soil to Q-S curve;the relationship between load sharing ratio of pile side and pile length;the proportion of aspect ratio to tip resistance.Analysis results show that these factors have significant affect on the bearing behavior of super-long single pile.
