本文进一步研究了我国大陆上强震的潮汐应力位相与地震序列类型的关系。不同类型的地震序列,其主震的潮汐最大剪应力的位相具有明显的优势分布。可以认为潮汐最大剪应力的位相是地震时地壳应力积累速率的一个标志。不同类型的地震序列的潮汐最大剪应力的位相和潮汐流体静应力的位相具有确定的组合特征,它与岩石力学实验中不同加载方式的应力途径实验结果相吻合。
This paper further studies the relationship between the tidal stress phase of strong earthquakes in China and the types of seismic sequences. Different types of seismic sequences have significant dominant distributions of the tidal maximum shear stress of the main shock. It can be considered that the phase of the tidal maximum shear stress is a sign of the crustal stress accumulation rate during an earthquake. The phases of the tidal maximum shear stress and the tidal hydrostatic stress of different types of seismic sequences have certain combination features, which are in good agreement with the experimental results of stress paths under different loading methods in rock mechanics experiments.
