This shows that the effectivetime interval of earthquake events is only about 1000 years, and the maximum cycle of seismic activity that we are allowed to infer does not exceed 500 years.
Curves of total stress and time, of cycle pore water pressure and time, of effective stress and time, of effective stress and axial strain are respectively studied.
研究了试样总应力、循环孔隙水压力、有效应力随时间的变化规律及试样有效应力与轴向应变的关系曲线。
