Suitability Study of Soil Liquefaction in Tainan Area by shear Wave Velocity Method

Abstract

Based on the shear wave velocity data obtained by the 12-hole Seismic Cone Penetration Test and referring to the soil data of the nearby SPT borehole the N values are converted into shears by the relationship between the seven SPT-N values and the shear wave velocity Force wave speed Next Andrus and Stokoe (2000) were used to calculate soil liquefaction potential and finally Iwasaki (1982) was used to assess the extent of liquefaction damage The liquefaction characterization point of Tainan is used to draw high medium and low potential ranges of soil liquefaction with Arc GIS After the analysis results the correct number of 8 holes was determined by SCPT in 12 holes and the accuracy was 67% The correct number of holes under the method of Seed and Idriss (1981) and Ni et al (1990) is 6 holes with an accuracy of 50% which is the second best
