Institute of Mechanics, CAS, Beijing 100080, P R China

摘要

摘要: 基于Yamamoto的多孔弹性介质模型,研究了波生底床的稳定性.通过给出的有限深底床下土响应分析解,针对三种土质底床,讨论了主要波参数和土参数对这些底床稳定性的影响.与其他土模型计算结果进行了比较,分析了海洋土内部Coulomb摩擦因素的影响.

Abstract: Based on the Yamamoto's soil model by considering the Coulomb friction effects,the wave-induced seabed instability has been investigated.An analytical solution is derived for soil response of a finite depth seabed under surface water wave.The effects of wave parameters and soil characteristics on the seabed instability are addressed for three types of soil.Finally,the roles of Coulomb friction stability are then analyzed as well.
