| dc.description.abstract | On February 6, 2016, the Mino earthquake caused a serious disaster in the Tainan area, so the Executive Yuan has indicated that the local governments with liquefaction potential areas is necessary to make a medium mapping liquefaction potential. Therefore, this thesis uses the above concept to draw the mapping liquefaction potential of Taipei Basin.
The work of the potential mapping is mainly to collect the borehole data, execute the liquefaction analysis and produce soil liquefaction maps. The method of HBF was developed by Hwang et al. (2005, 2012), is adopted to be the method of SPT-N value liquefaction analysis in this research and compared the results with Seed (1985), JRA (1996), NCEER (1997) and AIJ (2001) methods. The research examine the search radius of Inverse Distance Weighted in ArcGIS 10, and further produce potential maps.
The results of mapping liquefaction potential show that the HBF, the Seed and the NCEER are similar. According to the comparison of PL values and FS from different methods, the NCEER is the most similar to the HBF, the next one is the Seed. However, the JRA96 is the most conservative and the AIJ is the most opposite. The fixed search of IDW is more suitable than variable search for searching the boreholes of PL value. | en_US |
