| 摘 要： | 根据弹性应力波在连续介质中传播的基本理论, 讨论了一维二相介质中应力波的传播及相界面上的入射波、反射波。建立了应力波在界面上反射、入射所形成的最大界面应力模型, 并用海底富钴结壳及基岩的参数估算了钴结壳剥离时的界面效应, 结果表明, 结壳与坚硬基岩界面是一个最易产生破坏的面。

| Abstract: | According to basic theory on transmission of elastic stress wave in continuous medium, the authors discuss transmission of stress wave in one-dimensional and two-phase medium as well as incident wave and reflective wave on interface. The model of maximum interfacial stress forming by incidence and reflection of stress wave on interface is established and used to estimate the interfacial effect in cobalt-rich crust stripping using parameters of substrate rock and cobalt-rich crust. The results show that the interface between substrate rock and cobalt-rich crust is easiest to break. |
