Problem with deconvolution
I have been trying to deconvolve my seismic data, but it isn’t working properly. I have this soil profile:
Thickness 2.00 m // 6.00 m // 15.00 m // Half-Space Bedrock Vs 280 m/s // 390 m/s // 325 m/s // 1500 m/s UnitWeight 17 kPa // 20 kPa // 19 kPa // 22 kPa
I have tried different damping and G/G_max models (Darendeli, Vucetic, Ishibashi), but it doesn’t solve the problem. Input Motion: PAG=0,12 and PGV=41,35 (specify depth = 0)
When I compute to get the acceleration time series on the bedrock it returns an acceleration time series with values around 1E+19 g, which is very unrealistic. However, when I change the input motion to one with lower PAG and PGV, it works just fine.
Anyone knows how to solve this problem? Thanks.
