| 摘 要： | 本文通过对砂土中相同桩距、不同桩数、不同桩长的桩台基础模型的对比试验,分析了在垂直荷载作用下,桩尖刺入变形及承台荷载分担比随桩数、桩长变化的特性,研究了桩尖刺入变形随荷载增加而变化的规律,对桩尖刺入变形在桩土共同工作中所起的作用有一些新认识。

| Abstract: | In this paper, Based on the contrast experiments in sandy soil, the capped pile foundation models are set at equal pile spacing with different pile numbers and pile lengths. Under the vertical loads, the pile-tip penetration defermations, the percentages of cap loads vary with the pile numbers and the characteristics of the change of pile length are a analyzed. The law of change of pile-tip penetration deformations varies with the increasing of load is studied Some new views of the penetration deformations play a role in pile-cap interaction are acquired. |
