-
摘要: 本文采用稳态振动法,原位量测了上海高桥饱和粘性土在某些激振频率范围内的瑞利波的传播速度。文中也分析了与波传播速度有关的某些因素,并且提供了剪切波波速、动剪切模量和动弹性模量等的计算值。Abstract: This Paper reports the use of steady-state vibration technique in in-situ measurement of Rayliegh wave velocity, within certain exciting frequency range, in saturated cohesive soils at Gaoqiao District, Shanghai.This paper also reviews factors affecting wave velocity, with computed values of shear wave velocity, dynamic shear and elastic moduli etc.
