Effects of Earthquake on Behavior Characteristics of Fault Gouge in Time-History Analysis of Slope

Figure 8

Comparison of the scaled acceleration of the waveforms for the five earthquakes (M3.0, M3.9, M5.1, M5.4, and M5.8). The accelerations of the M3.9 and M5.8 earthquakes are the only ones that exhibit notable amplitude fluctuations in the Coda wave section. However, the R/P ratio for the M3.9 earthquake (red line) is high, at approximately 110%, whereas the R/P ratio for the M5.8 earthquake (blue line) is low, at approximately 50%. (a) Scaled acceleration for each earthquake. (b) Scaled acceleration within the Coda wave section for each earthquake.
