摘要
针对波传播分析理论的发展历程进行了简要的综述,详细介绍了几种处理粘弹性波传播问题的分析方法,重点讲解Laplace变换法以及Laplace变换在粘弹性波中的应用,对比分析几种方法在各自应用上的优劣,由于Laplace变换法能准确地描述应力波在任意时刻、任意点的波动情况,在处理大尺寸混凝土类构件中应力波传播问题时具有其独特的优势。
The development of analytical theory of wave propagation is briefly reviewed and several analysis methods dealing with viscoelastic wave propagation are introduced in detail.The Laplace transform method and its application in viscoelastic wave propagation and its advantage and disadvantage are described,compared and analyzed.The comparison shows that Laplace transform method has its unique advantage in dealing with the problems of stress wave propagation in large concrete components as it can accurately describe the fluctuation of stress wave at any time and any point.
