本研究蒐集臺南地區新鑽鑽孔的土層資料，採用HBF法、NCEER法、JRA(2012)法、T&Y法、AIJ法、JRA(1990)法及CBC法七種SPT-N值簡易經驗評估法評估土壤液化潛勢，並以2016美濃地震在臺南地區造成的液化表徵為參考標準，比較各評估方法之間的差異及在臺南地區的適用性、準確性；此外，亦探討JRA(2012)法中有無考量D_50、D_10此兩參數的差異、內陸直下型地震及板塊邊界型地震的參數選擇差異，以及NCEER法中從Seed簡易評估法的手繪圖表公式化而得的計算式，與原本手繪曲線圖的差異、契合性。
分析結果顯示，HBF法、NCEER法、JRA(2012)法及T&Y法較為接近且保守；其中，JRA(2012)法中的中高潛勢孔數高達82.2%；而以誤差平均值而言，T&Y法較接近HBF法。計算其餘6個方法對HBF法的液化潛能指數誤差，以平均值而言，與HBF法最接近的是T&Y法，其次是NCEER法，其餘都與HBF法相差較多，且T&Y法及NJRA法比HBF法還大，其餘皆比較小。就臺南地區來說，考慮D_50及D_10此兩參數的有無，對JRA(2012)法並沒有太大的影響。JRA(2012)法中，內陸直下型地震的評估結果，遠比板塊邊界型地震來的不保守，平均誤差達71%。檢視各方法其(非)液化案例屬高或低潛勢之鑽孔數比例，HBF法及JRA(2012)法在臺南地區的適用性較佳，AIJ法、JRA(1990)法及CBC法則較不適用，但與Iwasaki等人(1984)的經驗值相比，整體結果仍屬不佳。

The objective of this article is to compare the difference among seven simplified SPT-N value evaluation methods of soil liquefaction, and also to assess the suitability of these methods in Tainan area. The following are these seven simplified SPT-N value evaluation methods: HBF (2012), NCEER (2001), AIJ (2001), T&Y (1983), JRA (2012), JRA (1990) and CBC (2010). Besides, in JRA (2012), the difference between whether D_50 and D_10 are considered or not, Type I Earthquake and Type II Earthquake and in NCEER (2001), the difference between formulas and hand-painted diagrams in Seed’s simplified evaluation method will also be presented in this article. There are totally 653 soil profiles have been used in this article to perform studies stated above. To avoid mistaking two JRA methods from different years, JRA (1990) will go by “Iwasaki”, and JRA (2012) will go by “JRA”.

The results implies that values and distribution of liquefaction potential index(P_L) established by Iwasaki (1984) of HBF, NCEER, JRA and T&Y are similar and more conservative. Compared with AIJ, Iwasaki and CBC, the percentage and distribution of high potential borehole of these four methods are much more and more widespread; the highest percentage is JRA, up to 82.2%. When it comes to error HBF-based with other methods, on the part of average, T&Y is the nearest, NCEER is the next, and the other methods differ a lot from HBF. In Tainan area, it seems no significant difference between whether D_50 and D_10 are considered in JRA; also, the result of using Type I Earthquake is much more conservative than Type II Earthquake, and the difference is up to 71% in average. In view of percentage of number of boreholes of high liquefaction risk among liquefied cases or low liquefaction risk among non-liquefied cases, suitability of HBF and JRA are better, while AIJ, Iwasaki and CBC are worse. However, compared with experience from Iwasaki et al. (1984), the entire result of analysis is not very good.
