| 摘 要： | 为了研究桩侧法向应力、剪切带厚度变化对基桩强度参数影响情况,本文采用室内改制的四联剪切仪,进行了一系列的黄土和黄土与混凝土复合体的直剪和单剪试验。基于试验结果分析了桩侧剪切带的几何尺寸变化对桩土间强度指标等参数的影响情况,获得了力学参数变化规律等一系列结论,可为黄土地区的桩基工程建设提供一定的参考。

| Abstract: | In order to study the influence of the normal stress and the difference of the shear-zone thickness along the pile shaft to the strength parameters of the foundation piles,a series of direct shear tests and simple shear tests in loess or between loess and concrete are carried out by using the refitted box-shear apparatus.Based on the testing results the influece of the dimension change of the shear zone to the strength parameters is analyzed and the change law of the parameters is obtained,which could give a guidance for the pile construction in loess area. |
