| 摘 要： | 本文根据空间轴对称问题的有限元方法,在经过大量非线性弹性分析计算的基础上,研究了陕甘黄土地区的柔性桩——灰土井桩的桩型对桩竖直承载力的影响,并与现场试验的实测结果对比,证明了桩型效应客观存在的必然性和可靠性.指出改变圆柱形桩型而采用圆楔形桩型是提高灰土井桩承载力的有效途径之一.

| Abstract: | The paper principally discusses the effects of pile's shapes on bearing capacity of different shaped lime-soil bearing piles based on a large 3D nonlinear analysis of finite element. By comparing with the test data, it is proved that the pile's shape effects is reasonable and reliable, and point out that making use of the inverted frustum of a cone lime-soil bearing pile should be one of efficacious way to improve the bearing capacity of lime-soil pile. |
