The application of surface wave method for site investigation becomes more and more popular in practical uses due to its non-intrusive tests and convenient operations. In particular, multi-station recording permits a single survey of a broad depth range and high levels of redundancy with a single field configuration. However the field testing configuration plays a major role to ensure good data quality for constructing a dispersion curve with a wide range of frequencies. The adjustments of field configuration usually need experienced testers' "educational guess" after referring to the results from preliminary tests for ensuring the data quality. This guessing process makes the surface wave method an unfriendly technique for general field engineers. The effects of survey line parameters, such as near offset, receiver spacing, and offset range, are investigated and respective criteria for deciding the proper configuration are illustrated. Furthermore, a new concept called "pseudo-section" is introduced to synthesize a series of data for selecting optimum offset range for each frequency and increasing the lateral spatial resolution. This study will lead to further standardization of the surface wave testing.
