Abstract

A new autosoliton view is developed for the seismic process. In physical terms, faults correspond to stationary autosolitons, and inter- and intrafault deformation disturbances are traveling autosolitons. Slow dynamics reveals itself only on large time scales because slow autosoliton disturbances, as a rule, have velocities 4–7 orders of magnitude lower than the sound velocity. It is shown that, in the loaded strong medium, slow autowave and autosoliton disturbances are generated by short dynamic actions (pulses) at interfaces. In real geomaterials, these are block boundaries and various-scale faults. Dynamic movements of structural elements cause the deformation autowaves and autosolitons to propagate from the interfaces into blocks and along faults. Velocities of such deformation autowaves and autosolitons are low and proportional to velocities of the related movements of structural elements in the geomedium. Propagating in structural elements that are in a certain stress-strain state, deformation autowaves and autosolitons can be taken as small disturbances of the existing fields of the stress-strain state. A mathematical model is represented for the geomaterial treated as a nonequilibrium randomly inhomogeneous medium. Special features of the generation and propagation of deformation autosolitons in such media are studied.

地震过程的自孤子视图。第 1 部分。 Geomedia 中慢变形自孤子扰动的产生和传播的可能性

摘要

为地震过程开发了一种新的自孤子视图。在物理方面，断层对应于静止的自孤子，断层间和断层内变形扰动是移动的自孤子。慢动力学只在大的时间尺度上显现出来，因为慢自孤子扰动的速度通常比声速低 4-7 个数量级。结果表明，在加载的强介质中，界面处的短动态作用（脉冲）会产生慢自波和自孤子扰动。在真实的地质材料中，这些是块边界和各种规模的断层。结构元素的动态运动导致变形自波和自孤子从界面传播到块体并沿着断层传播。这种变形自波和自孤子的速度很低，并且与地质介质中结构元素的相关运动速度成正比。在处于一定应力-应变状态的结构单元中传播时，变形自波和自孤子可以看作是对现有应力-应变状态场的微小扰动。将地质材料视为非平衡随机非均匀介质的数学模型表示。研究了这种介质中形变自孤子的产生和传播的特征。将地质材料视为非平衡随机非均匀介质的数学模型表示。研究了这种介质中形变自孤子的产生和传播的特征。将地质材料视为非平衡随机非均匀介质的数学模型表示。研究了这种介质中形变自孤子的产生和传播的特征。
