SASW Test along Line 5 using T-Rex

SASW tests along Sensor Line 5 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. “Line5_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.面波频谱分析（Spectral Analysis of Surface Waves, SASW）测试沿5号传感器线开展，以获取用于三维剖面反演的剪切波速剖面。本次三维剖面测试采用沿该线布设的4个检波器，检波器布设间距为10米。本次面波测试分别测试了60米、40米、20米及10米四种传感器布设间距。由编号为21279的Quattro分析仪提供的阶跃正弦信号，用于驱动T-Rex设备，并采集选定检波器的输出信号以开展面波测试。 "Line5_SASW_T-Rex_GV_V3_Channel_Map.csv"文件列出了本次三维剖面测试中使用的全部传感器。本次面波测试所采用的传感器测站信息，可在每次试验的"Description"字段中查阅。关于测试布设方案与测试结果的详细说明，可参阅配套文档中的面波测试报告。
