Synopsis
gpsh [OPTIONS] [FILE]
Description
Computes the SH transfer function for layered models given through stdin or FILE.
The input is the soil column defined as listed below] The output is the Fourier transfer function for VERTICALLY INCIDENT plane S waves
Format for layered models:
Line 1 : <number of layers n including half-space for first model> Line 2 : <thickness (m)> <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>] .... Line n+1 : 0 <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>] Line n+2 : <number of layers m including half-space for a second model - if wished> Line n+3 : <thickness (m)> <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>] .... Line n+m+2 : 0 <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>] Line n+m+3 : <number of layers l including half-space for a third model - if wished> ....
Quality factors are mandatory. Any number of models can be given as input.
Gpsh options
- -n <count> Number of samples (default=100)
- -max <max> Maximum of range for transfer function (default=20)
- -angle <angle> Incidence angle (default=90, vertical incidence)
Generic options:
- -help <SECTION> Show help about options. SECTION may be empty or:
all, examples, generic, gpsh
- -version Show version information
- -app-version Show short version information
- -reportbug Start bug report dialog, information about bug is
passed through stdin. This option is used
internally to report bugs if option -nobugreport is
not specified.
- -reportint Start bug report dialog, information about
interruption is passed through stdin. This option
is used internally to report interruptions if
option -nobugreport is not specified.
- -nobugreport Do not generate bug report in case of error
Examples
gpsh < test.model
Calculate SH transfer function from 0.2 Hz to 20 Hz for model 'test.model'.
gpsh < test.model | figue -c
Calculate the same function and plot it.
gpsh < test.model | figue -c -m sh.mkup
Show the same function on a log-log plot. 'sh.mkup' is a tar.gz file containing an xml description of the graphic format, it can be generated from figue's interface.
