| 摘 要： | 采用静力触探资料估算单桩竖向承载力的方法经大量的工程实践证明是行之有效的 ,它可以充分发挥地基土的潜力 ,节省工程投资。但对于某些处于深厚软粘土中的桩 ,按规范规定的休止时间进行试桩时 ,实测的单桩极限承载力有时与理论计算结果相去甚远 ,本文结合具体工程实例详细说明了在工程中遇到此类问题的几种的处理措施 ,提出了此类地层中确定单桩竖向承载力的一些建议。

| Abstract: | From a variety of engineering practices it is proved that the method to determine the bearing capacity of single pile with CPT data is effective, which can fully make use of the potential capacity of subsoil so as to reduce the investment.When the pile-loading tests are carried out for the piles in deep soft clay according to the testing end time listed in national code,the bearing capacity from the testing has a great difference with the results from the calculation.Through engineering examples some measures to deal with such problems are presented, and suggestions on the determination of the bearing capacity of single pile is also given. |
