| 摘 要： | 为促进对桩-土-承台相互作用规律的认识,本文主要运用ABAQUS模拟了锚杆静压桩(方桩)的不同桩长、桩边长、桩间距、桩数以及承台厚度情况下,锚杆静压桩群桩基础的工作性状。桩长的增长和桩数的增加,都会导致群桩效应系数和承台荷载分担比的降低;而随着桩间距增大群桩效应系数和承台荷载分担比增大。这些结论都有助于指导桩基设计,使得桩基设计更符合其实际工作状况。

| Abstract: | In order to improve comprehension for the rule of interaction between pile,soil and pile caps,the software ABAQUS was applied to stimulate the different working properties of anchored silent group piles’ foundation under different pile length,side length,pile spacing,number of pile and thickness of piles cap.The effect coefficient of group pile and undertaking ratio of pile cap will decreased with the increase of pile length and number of piles,but not the pile spacing.The results will be useful to the guidance of pile foundation design and make the design of pile to accord with real working conditions. |
