摘要
运用动力学分析方法,对桐柏—大别造山带碰撞造山作用的动力学机理与过程进行了粗略探讨。分析表明造山过程中存在着种种非线性效应的影响,从而造成了相应构造变形过程中的失稳与突变,并改变了应力与应变分布的状况。文中就应力波的传播讨论了碰撞作用的持续时间等问题。并指出一些看似复杂且性质迥异的地质现象和事件实际上是同一种动力学机制在不同阶段、不同侧面的反映。
By means of the dynamic analysis, the mechanism and process of Tongbo -Dabie erogenic belt's collision orogeny in Mesozoic are studied. The results show that the steady -lose and morphogenesis might occur because of nonlinears in the process. The distribution of the stress and the strain in the collision plate might also change with the same reason. In terms of finding out the regulation of stress wave spreading the lasting time of collision is deduced. From this, it can be said that some different complex geologic questions are a reflex of the same mechanism as a matter of fact.
