利用大型土工离心机对5个桩基码头物理模型的数据进行了惯性需求和运动需求的相互作用研究。本研究中的码头结构受到一系列记录的地面运动的影响，因此相关的上层建筑惯性和地震引起的不同震级的斜坡变形。这些测试的观察结果用于提供如何估计在桩头和深度明显低于通常假定的与深层地面变形相关的固定点的大弯矩的见解。设计建议提出了如何结合惯性和运动学的要求，以一种方式，是整体结构的代表。
The interaction of inertial and kinematic demands is investigated using data from five physical models of pile-supported wharves using a large-scale geotechnical centrifuge. The wharf structures in this study were subjected to a suite of recorded ground motions, therefore associated superstructure inertia, and earthquake-induced slope deformations of varying magnitudes. The observations from these tests were used to provide insights on how to estimate large bending moments that developed at pile head and at depths significantly below a commonly assumed point of fixity that are associated with deep-seated ground deformations. Design recommendations are proposed on how to combine inertial and kinematic demands in a manner that is representative of the global structure.
