离心试验中波在土中的传播
Wave propagation through soils in centrifuge testing
摘要：
波在土壤中的传播现象可以用离心模型进行实验模拟。提出了一种新颖的激励装置（落球布置）来产生短波列。模型边界上的波浪反射被考虑在内，并通过同态滤波去除。传播通过色散规律进行了研究。对于落球实验，球面波场分析假设线性粘弹性导致波传播的完整的分析描述。阻尼现象进行检查和评估使用此描述。
英文摘要：
Wave propagation phenomena in soils can be experimentally simulated using centrifuge scale models. An original excitation device (drop-ball arrangement) is proposed to generate short wave trains. Wave reflections on model boundaries are taken into account and removed by homomorphic filtering. Propagation is investigated through dispersion laws. For drop-ball experiments, spherical wave field analysis assuming linear viscoelasticity leads to a complete analytical description of wave propagation. Damping phenomena are examined and evaluated using this description.
