【摘要】 文章设计实现了支盘桩-土-上部结构动力相互作用体系的振动台模型试验。试验要求支盘桩-地基土-上部结构之间遵循相同的相似关系;按照Bockinghamπ定理导出试验模型各物理量的相似关系式和相似系数;根据振动台设备和边界条件的要求选用试验用模型土箱和试验用土;按照模型相似关系设计了结构体系的施工图;设计了自由场试验和系统振动台试验的加载制度。试验设计确定了试验的基本原则和实现方案,为进一步的研究奠定了基础。更多还原

【Abstract】 In this paper,the shaking table test of a squeezedbranch pile-soil-structure dynamic interaction system is designed.The piles,soil and structure adhere to same similar relations.The similar relation and likeness coefficient are derived according to the Bockingham π theorem.The soil box and the experiment soil are selected according to the requirement of the shaking table and boundary conditions.The working drawing of the system is designed according to the similar relation.The loading systems of the free field experiment and pile-soil-structure system experiment are also established.The fundamental principles and implementing scheme of the shaking table test are described.更多还原
