This study had been executed employing Seismic Refraction Tomography (SRT) and Multichannel Analysis of Surface Waves (MASW), to integrate elastic and bearing capacity with engineering criteria within delineation for seismic microzonation besides menace assessment. Forty eight and eight SRT and MASW outline through an aggregate distance of about 484 m breathe constrained toward characterizing topsoil variables conducive to site characterization. 12 kg sledge hammers with 1.0 m diameter aluminum disc, twenty four channels (ES 30000 S) enhancement seismographs were used as seismic sources, detectors, and recorders. P and S wave’s velocities breathe attained as well as delineated employing SRT and MASW techniques via beget 2D/3D velocity depth model. The elastic, bearing capacity and engineering parameters calculated were: Elastic/rigidity modulus, Poisson ratio, allowable.. View More»
