| 摘 要： | 结合浙江地区某工程实例,利用MIDAS/GTS有限元分析软件对单桩竖向承载性能进行模拟分析,对载荷与沉降关系及桩体应力变化规律进行比较,模拟分析结果表明不同宽度横向中间凸肋对竖向承载性能影响为随宽度增加沉降量减少、承载力提高。

| Abstract: | Combining with a practical project in Zhejiang,the vertical ultimate bearing capacity of single pile is simulated and analyzed by using MIDAS/GTS,comparing the different load and settlement relations as well as the variation of the pile stress,and the result shows that the vertical ultimate bearing capacity will be affected by different annular flange rib width of middle: with the increase of the width,the settlement will reduce and the bearing capacity will improve. |
