- Abstract:
- Using the stochastic finite fault time history simulation program, we simulated the horizontal component acceleration time history in accordance with the regional characteristics of Wenchuan earthquake, and analyze the spatial distribution and variation law of simulated acceleration time duration. The results show that the distributions of each time duration of simulated acceleration time history can reflect the rupture directivity effect of time duration, but can not clearly reflect the upper/lower disk effect. Moreover, the significant duration of simulated acceleration time history can reflect the characteristics that the duration in near fault area is obviously smaller than that in far field, but it is more “single” in the overall spatial distribution and does not show obvious regional “mutation” phenomenon. Compared with the significant duration, there is a greater difference between the simulated acceleration duration and the Bolt holding time recorded by the station. The changing trend of these two durations could generally reflect the spatial variation characteristics of the horizontal component recording with the fault distance.
