本文的目的是对复杂应力作用下的地壳构造块体（活动断裂）间界面的受力和变形响应特征进行综合研究。将接触块体视为典型的摩擦副进行研究。这使作者建议调查的影响，振动和润滑引起的接触区的物理机械性能的变化（这是通过浇水实现）的最大值的滑动阻力和制度的相对切向块位移（滑动）。有人发现，结合使用浇水和"高频"振动从根本上改变了界面区域的响应状态，并可以启动广泛的，但地震安全的"平滑"位移的地质块沿着故障。基于汤姆林森模型的研究结果分析表明，对于不同性质的摩擦副，结构单元间边界响应特征（包括滑动状态）的变化具有普遍性。通过对研究结果的分析，提出了人工控制沿着地震活动断层位移的新途径。这种方法似乎是未来地震灾害管理的重要工具。
The objective of this paper was to perform the complex study of features of force and deformation response of interfaces between structural tectonic blocks in the Earth's crust (active faults), which are under complex stress. The research was based on consideration of contacting geoblocks as typical friction pairs. This allowed authors to suggest investigation of influence of vibrations and also of lubrication induced change of physico-mechanical properties of the contact zone (this was realized by watering) on the maximum value of sliding resistance force and regime of relative tangential block displacement (slip). It was found that combined use of watering and “high-frequency” vibration fundamentally changes response regime of interface region and can initiate extensive but seismically safe “smooth” displacements of geo-blocks along the fault. Analysis of investigation results on the basis of Tomlinson model shown that revealed change of response character (including sliding regime) of boundaries between structural elements is general for friction pairs of various natures. Analysis of research results allows authors to propose the new approach to manmade control of displacements along seismically active faults. This approach seems to be an important tool in the management of seismic hazards in the future.
