In this research, synthesized approach of the sounding results and the shear wave velocity is proposed to evaluate the distribution of the ground strength. For this task, the surface wave method is used to obtain the shear wave, and the piezometer cone penetration test (CPT) is employed as a sounding test. The CPT N value, Nc is derived from the results of CPT, namely, the tip resistance, the side friction and the pore water pressure, and transformed to the standard penetration N value, NSPT. The shear wave velocity Vs is also transformed to NSPT. Two kinds of NSPT are applied to the indicator simulation method (IS), which is one of the geostatistical approaches, and the IS can synthesize two NSPTs. The spatial distribution of the NSPT is simulated by the IS. The method to incorporate the two kinds of the transformation errors from Nc to NSPT, and from Vs to NSPT into the IS, is proposed in this research. Consequently, the effect of the transformation errors on the simulation results has been clarified.
