Abstract

The purpose of the research is to find possible ways to use microseisms, caused by standing waves in water bodies. According to the theory, standing waves arise when two traveling waves, moving towards each other collide. The first of them falls on an obstacle and the second one reflects from it. The conditions of excitation the waves and swinging of damped waves are presented. Evidence shows that the wave pressure at the antinodes at the boundaries of the water medium separation and the soil is proportional to the wave amplitude on the water. The possibility of using standing waves in seismic exploration is confirmed by the observation data of storm microseisms at remote stations. To increase the transmission range, it is advisable to use long-period microseisms, which provide low damping. One method to reduce the risk of an earthquake involves the initiation of weak seismicity by artificial sources in order to periodically relieve excess tectonic stress. One of the most powerful sources of lithospheric deformations is the natural oscillations of the liquid level in large water bodies. The study considers the idea of using the resonance effect of tidal-seiches vibrations to initiate weak seismicity. Artificial excitation of the seiche is achieved when controlling a water culvert. Transmission network supports multiplexing of communication channels with separation by physical nature and transmission media. When managing culverts, seiches oscillations are artificially swung with phase-shift oscillations. Phase shift of the exciting wave relative to the damping wave, in turn, causes variations in seiche periods, which leads to proportional variations in the periods of microseisms. This solution allows encoding messages by the durations of seiches and microseisms, with their subsequent transmission. Hydrological observations revealed the effect of the dependence of surface seiches periods on water depth. The solution of the inverse problem, with the measured seiches period, allows calculating the water body depth. Method of remote measurement has been proposed using the analysis of ground oscillations of seiches origin. Analysis of variations in the electromagnetic radiation of the geological environment has shown that they are determined by the mechanisms of energy conversion of these processes into the energy of the electromagnetic field. The study of these variations allows us to calculate the depth of the water body. Originality. Methods for using microseismic oscillations excited by standing waves are considered in detail. The methods of managing standing waves are presented: by regulating the depth of the reservoir; by regulating the period of the exciting wave; by regulating the phase of the exciting wave. The dependence of the amplitude of the resulting oscillation of standing waves on the phase of the exciting oscillation of the same period was investigated. Innovative developments protected by patents of Ukraine are presented, which imply the economic use of microseisms caused by standing waves of water bodies. It is noted that both the necessity and the possibility for using one or another method of performing a specific task are determined by internal and external objective conditions that exist at a certain time in a certain space.

这项研究的目的是寻找利用微地震的可能方法,微地震是由水体中的驻波引起的。根据该理论,当两个相互移动的行波碰撞时,就会产生驻波。第一个人落在障碍物上,第二个人从障碍物上反射过来。给出了阻尼波的激励、振荡和振荡条件。有证据表明,在水介质分离和土壤边界的波峰处的波压与水面上的波幅成正比。远站风暴微震观测资料证实了驻波在地震勘探中的可行性。为了增加传输范围,建议使用提供低阻尼的长周期微震。减少地震风险的一种方法是通过人工震源引发弱地震活动,以便周期性地减轻过量的构造应力。岩石圈变形的最有力的来源之一是大水体中液位的自然振荡。该研究考虑了利用潮汐震动的共振效应来引发弱地震活动性的想法。在控制涵洞时,可实现人工激发积水。传输网络支持通信信道的多路复用,通过物理性质和传输介质进行分离。当管理涵洞时,seiches振荡被人为地用相移振荡摆动。激发波相对于阻尼波的相移又引起地震周期的变化,从而导致微震周期的成比例变化。该解决方案允许根据地震和微地震的持续时间对消息进行编码,并进行后续传输。水文观测揭示了地表沉降期对水深的依赖性。反问题的解,与测量的洪水周期,允许计算水体深度。通过对地震震源地震动的分析,提出了遥测地震震源的方法。对地质环境电磁辐射变化的分析表明,它们是由这些过程转化为电磁场能量的机制决定的。对这些变化的研究使我们能够计算出水体的深度。创意。详细讨论了利用驻波激发的微震振荡的方法。提出了控制驻波的方法:通过调节水库深度;通过调节激励波的周期;通过调节激发波的相位。研究了驻波振荡的振幅与同周期激振的相位的关系。介绍了受乌克兰专利保护的创新发展,这意味着由水体驻波引起的微震的经济利用。需要指出的是,使用一种或另一种方法执行特定任务的必要性和可能性,是由在一定时间、一定空间存在的内外客观条件决定的。
