Delineation of elastic properties and settlement of dam materials at the dam embankment using seismic methods
Summary Seismic refraction tomography and MASW analyses provided 2D compressional (Vp) and shearwave (Vs) velocity sections along the crest and downstream side of the Klong Sadao dam. The results of Vp and Vs investigation have shown that the settlement of material of the dam embankment is increasing with depth. Based on Vs30 values, the area falls in site class C and D, indicating the stiff soil to dense soil and soft rock beneath the dam. There are noticeable regions of weak zones as indicated by determined Poisson’s ratio. In addition, the calculated predominant period of the dam suggest that local earthquake with 0.1-0.4 s period can pose significant threat to the dam.
