受限於可施加高速及高頻之剪動設備相對缺乏，現今砂土液化相關研究，在近斷層加載方面相對欠缺，本研究之目的為使用中空扭剪探討砂土在近斷層加載下之液化行為。本研究採用乾淨砂試驗之，並以九二一集集大地震之近斷層地震歷時作為試驗內容，並將結果與正弦波反覆剪應力之液化試驗結果進行比較。分析結果顯示，高頻脈衝之剪力波形最大剪應力比與液化阻抗(CRR)之比值約略為0.45，而顯著脈衝之比值則約略為0.35；在臨界液化之週期數方面，高頻脈衝狀態下為3個週期數，顯著脈衝則約略為1至2個週期數；以能量觀點分析，可發現高頻脈衝性質之剪應力歷時在剪動能量累積至60%以前即發生初始液化，顯著脈衝性質之剪應力歷時則須在能量累積至70%之後才有液化之可能。

Limited by the lack of shearing equipment capable of applying high speed and high frequency, the current research on sand liquefaction is relatively lacking in near-fault loading. The purpose of this study is to investigate the liquefaction of sand under near-fault loading using hollow cylinder apparatus. In this study, the clean sand test was used, and the near-fault seismic duration of the 1999 Chi-Chi earthquake was taken as the test content, and the results were compared with the liquefaction test results of the sine wave repeated shear stress. The analysis results show that the ratio of the maximum shear stress ratio to the cyclic resistance ratio (CRR) is about 0.45 in the waveform of high-frequency pulse, while the ratio of the significant pulse is about 0.35. In terms of the number of cycles in critical liquefaction, the high-frequency pulse corresponds to 3 cycles, and the significant pulse is about 1 to 2 cycles. From the energy point of view, it can be found that initial liquefaction occurs before the energy accumulates to 60% in the waveform of high-frequency pulse, while the waveform of the significant pulse must be liquefied after the energy has accumulated to 70%.
