本研究的目的是阐明在水平荷载作用下钢管板桩基础中连接部件的力学行为。SPSP的基础结构是将地面各SPSP的节点耦合，并在节点内注入砂浆。为此，在明确SPSP节点力学行为的基础上，讨论SPSP基础的力学行为。而在侧向荷载作用下的设计准则中，仅考虑节点部件的竖向剪切是临界的。因此，本研究通过模型试验和三维有限元法的再现分析，对SPSP基础的横向承载能力进行了精确的理解。简单地说，通过对SPSP模型进行横向加载试验并进行三维有限元再现分析，发现横向加载引起平行于加载方向布置的桩节点发生竖向剪切位移，而垂直于加载方向布置的桩节点几乎没有发生位移。
The aim of this study is to clarify the mechanical behavior of the joint parts in a steel pipe sheet pile (SPSP) foundation under horizontal loading. The foundation structure of SPSPs is constructed by coupling the joints of each SPSP in the ground with the injection of mortar into the joints. For this purpose, the mechanical behavior of the SPSP foundation should be discussed with a clear understanding of the mechanical behavior of the SPSP joints. In the design criteria under lateral loading, however, only the vertical shearing of the joint parts is considered as critical. Accordingly, the precise understanding of the lateral loading capacity of the SPSP foundation was investigated in this study through model experiments and a reproduction analysis by the 3D finite element method. Simply stated, from the lateral loading tests on the SPSP models and their reproduction analysis by a 3D FEM, it was found that the lateral loading causes vertical shear displacements of the joints of the piles arranged in parallel to the loading direction and almost no displacements of the joints of the piles arranged perpendicularly to the loading direction.
