| 摘 要： | 通过对某桥梁桩采用两种测试方法成果的对比,揭示锚桩法与自平衡方法测试中桩体反应的异同.考虑测试顺序影响后,在相同荷载水平下,自平衡法测试的位移、桩端阻力比例均大于锚桩法测试的,桩侧摩阻力-位移曲线则稍有不同.在鞍辽地区广泛分布的粉质粘土中,桩侧阻修正系数采用规程规定值是合理的.

| Abstract: | On the bridge piles under the anchor pile method and the self-balanced method are studied,the difference between the two different methods is illustrated.When considering the testing process,the displacement and the proportion of the end resistance of the self-balanced method are larger than those of the anchor pile method under the same load.The curves of the side friction-displacement between the two different methods are slightly different.Correction coefficient of the pile side friction in the silty cla... |
