2018年Taylor&Francis Group，伦敦。作为开发对桩的循环影响量化框架的研究项目的一部分，在澳大利亚珀斯的海上基础系统中心(COFS)对干燥的石英砂中的单桩和群桩进行了离心机模型试验。在单向和双向横向循环荷载作用下，研究了桩的竖向和水平荷载-位移特性。沿桩身放置的应变计提供了有关弯曲行为的信息。本文介绍了单桩的试验情况，着重讨论了荷载类型、循环荷载幅值和循环次数对观测响应的影响。作为一般承载性能的特征值，还对路基反力模数的循环性能进行了计算。

As part of a research project to develop a framework for quantifying cyclic effects on piles, centrifuge model tests on single piles and pile groups in dry silica sand have been carried out at the Centre for Offshore Foundation Systems (COFS) in Perth, Australia. The piles were subjected to lateral 1-way and 2-way cyclic loading, investigating the vertical and horizontal load-displacement behaviour. Strain gauges located along the pile shaft provided information about the bending behaviour. This paper presents the tests on single piles and highlights the influence of load type, cyclic load amplitude and number of cycles on the observed response. As a characteristic value for the general bearing behaviour, the cyclic performance of the modulus of subgrade reaction is calculated additionally.
