摘要
以相似理论为基础,采用原型粉粘土和微混凝土挤扩支盘桩制作相似模型,通过对桩土共同作用模型中支盘桩的承载能力、变形特征、土层的压力变化和桩土阻力及沉降关系的观测,分析了支盘桩支盘的作用特性以及与全桩承载力的关系,为支盘桩的工程应用提供了有价值的参数和实验依据。
Based on the similarity theory,a similar model of piles with branches and plates was designed and built.Through the observation on the bearing capacity,characteristic of deformation,soil pressure variation and the frictional force between pile and soil with the settlement of the soil,the behavior of branches and plates and bearing capacity behavior of piles have been studied and analyzed.The achieved results of the model test provides valuable parameters and testing data for engineering application of piles with branches and plates.
