摘要

摘要: 对称双斜桩基础是斜桩基础用于建(构)筑物的基本基础形式。通过对桩身竖向倾角分别为0、5、10、15和20的对称双斜桩基础模型试验,研究竖向荷载作用下对称双斜桩基础的承载特点。研究发现,对称双斜桩基础在竖向荷载作用下,随着桩身倾角的增加,当桩身对竖向的倾角在5～10时,其竖向承载力比直桩基础大,当桩身对竖向的倾角超过10时,其竖向承载力随桩身倾角的增加逐渐减小,并小于直桩基础的承载力;根据该模型试验,对称双斜桩基础当桩身对竖向的倾角在5～10内是最优的。

Abstract: The foundation with symmetric double batter piles is the main type,which is used for buildings and structure.The model experiments were done.The angles of the batter piles were 0,5,10,15,and 20 separately.The characteristics of the vertical bearing capacity were analyzed.The study indicated that under the vertical load as the angle of the batter pile was between 5 and 10,the vertical bearing capacity of the foundation was more than the one with vertical group piles.When the angle was more than 10,the vertical bearing capacity of the foundation decreased and even less than the one with vertical group piles．
