| 摘 要： | 通过对桩土分担荷载之比和桩土安全系数各自取值的影响的分析,提出用分项系数法对复合桩基整体承载力安全系数进行定义,并且分析了影响复合桩基安全系数的因素。在计算复合桩基整体承载力安全系数时,考虑了由于遮拦作用而使土的极限承载力有所提高以及考虑了群桩效应而使桩的极限承载力的变化,使得复合桩基整体承载力安全系数的定义和计算趋于更加合理和完整。

| Abstract: | The component method is presented after the discussion on the factors influencing the safety factors of a compsoite pile foundation.It’s suggested that the ultimate bearing capacity of soil should be increased because of the pile under the caps of composite foundation and the ultimate bearing capacity of pile should be changed because of the effect of group piles.The definition and calculation of the safety factors of foundation is reasonable and integral. |
