SASW Test along Line 2 using T-Rex

SASW tests along Sensor Line 2 to obtain shear wave velocity profile for the 3D profiling inversion. Tests utilized the 4 geophone placed along the line during for the 3D profiling tests. Spacing between geophones are 10 m. Sensor spacing of 60, 40, 20, and 10 m are tested in the SASW tests. Stepped-sine function provided by Quattro analyzer (Serial # 21279) is used to drive T-Rex and record output from selected geophones for the SASW tests. “Line2_SASW_T-Rex_GV_V3_Channel_Map.csv” file shows all the sensor used in the 3D profiling tests. The sensor stations used in the SASW tests are described in the “Description” field in each trial. A detailed description of the test setup and test results can be found in the SASW test report in the documentation.
