固体潮汐的研究是地球物理领域的研究热点,与地震预报的联系也十分紧密。借鉴固体潮汐与地震相关性的研究成果,建立了弹性地球模型,从固体潮理论出发,推导出地表潮汐应力的表达式。通过在常见的边坡破坏模式稳定性系数计算公式加入固体潮汐应力的作用,并选取典型算例,阐述固体潮对边坡稳定性及其时间效应的影响,论证了边坡的稳定性具有日周期变化的特征,提出在边坡防护的设计中应适当的考虑固体潮汐带来的影响。
The research of solid tide is a hotspot in the field of geophysics and closely linked with the earthquake prediction. Based on the research results of the correlation between solid tides and earthquakes, an elastic earth model is established. Based on the solid tide theory, the expression of surface tidal stress is deduced. The effects of solid tides on the stability of the slope and its time effect are illustrated by adding the effect of the solid tide stress to the common slope failure mode stability coefficient calculation formula and selecting typical examples. The stability of the slope with day The characteristics of the periodic variations are proposed. The design of slope protection should be properly considered the impact of solid tides.
