PRELIMINARY STUDY ON BEHAVIOR OF MODEL PILE FOUNDATIONS IN SAND USING SHAKING TABLE

摘要: 通过振动台试验,对群桩基础模型和桩筏基础模型在水平荷载作用下的动力反应进行了研究。试验内容包括对单独的地基模型;在地基模型中安装群桩基础模型;在地基模型中安装桩筏基础模型的3种振动试验和砂土的三轴试验。结果显示,如果能选择合理的相似性准则,可以利用振动台试验对桩基础在振动荷载下的动力行为进行分析。

Abstract: This paper presents the results of preliminary experiments related to behavior of model pile foundations, including pile group and piled raft, in a sand under seismic loading using a shaking table. The preliminary experiments consisted of shaking table tests on the model ground alone, and the pile. groups and the piled rafts installed in the model ground. Triaxial testing of the sand was also carried out. The test results suggest that the shaking table test is applicable to investigate the behavior of pile foundations under seismic loading, if an appropriate similitude rule is employed to interpret the shaking table test results.
