The scheme determination of foundation by field experiment to be sure, in order to accurately determine the scheme, based on the shear wave velocity method. Basis of komsomolsk jiangxi province south lake area new town of geotechnical engineering, the local field soil stiffness) (shear wave velocity test, collecting data through the three waveform record. By communication with computer, and transmit data from the instrument to the computer, the shear wave velocity of soil is obtained after processing, in turn, determine the type of construction field, the result is a characteristic value should be with single pile vertical bearing capacity of the single pile vertical static load test to determine, the number of piles in the same conditions of not less than 1% of the total, and not less than three, the group should be considered in the design of pile caps group effect of pile caps. Therefore, reasonable use of shear wave velocity test, can accurately determine the foundation plan.
