| 摘 要： | 针对吉林市雾凇立交桥试桩单桩竖向抗压静载承载力试验未达到破坏荷载时,如何判定无特征点的缓变型Q-s曲线的单桩极限承载力的问题,提出采用斜率倒数法、百分率法和港口工程桩基规范法等方法进行解释,并将其推算的结果进行综合对比分析以确定该桩的单桩竖向极限承载力。计算结果表明,该方法合理可靠,具有较高的精度。

| Abstract: | Aiming at how to judge the limit bearing capacity of single pile without flag and with transition Q - s curve while the collapse load isnt attained during vertical bearing capacity compression trial at static load for single pile of Wusong separation bridge in Jilin City, the paper puts forward that this problem is solved by slope reciprocal method, percentage method and specification method for port engineering pile foundation. And the calculated results have been synthetically analyzed to determine the limit vertical bearing capacity of single pile ,which has indicated that above methods are reasonable and reliable,having a higher accuracy. |
