| 摘 要： | 针对横向荷载作用下“前板桩、后方桩”高桩承台结构,运用有限元法建立三维空间模型进行计算分析,总结出土抗力系数、入土桩长和桩径等因素的变化对桩顶位移、桩身弯矩的影响程度.结果表明：增大桩截面面积,提高桩基抗弯刚度能减小桩的水平位移,特别是适当提高后排方桩的抗弯刚度,效果将更为明显,这是由于其能使前后排桩的弯矩分配更趋于合理化与均匀化. |
| 关 键 词： | 高桩承台 双排桩 入土桩长 |

| Abstract: | The 3-D model is founded by finite element method for elevated pile cap,which consists of sheet piles in first row and square piles in second row.The influent factors of displacement on top of pile and flexure moment of pile is analyzed,such as the change of soil resistance coefficient,pile length,pile's length in ground,pile diameter etc.The result shows that the pile's flexural rigidity increases and the horizontal displacement reduces by increasing the pile's section area.It is effective for the readjust... |
| Keywords: | elevated pile cap double-row pile pile's length in ground |
