Blind detection of liquefaction by existing methods for New Zealand M_L6.3 earthquake on Feb. 22,2011

Earthquake Engineering and Engineering Vibration 2011年第4期10卷 465-474页

Real-time liquefaction monitoring and warning techniques are new ways to mitigate liquefaction hazard. A key point is to establish a reverse liquefaction detection method based on seismic records. However, the existing methods are quite limited and the reliability requires verification. On Feb. 22, 2011 an earthquake of magnitude 6.3 struck at New Zealand＇s South Island. Remarkable liquefaction phenomena were reported, which provide an opportunity to verify the existing liquefaction detection methods. 27 acceleration records within 50 km to the epicenter were selected to perform a blind detection by using the existing methods, including Miyajima method, Suzuki method, Kostadinov-Yamazaki method and Yuan-sun method. The blind detection results indicate that Yuan-sun method gives correct results for seven confirmed sites, and Suzuki method and Yuan-sun method yield correct detection for a reported non-liquefied site. Four methods including the Yuan-sun method give identical detection for four sites and three methods also including the Yuan-sun method give identical detection for ten sites. Besides, there are five sites, for which the four methods give opposite detection.

研究具有代表性的Kostadinov and Yamazaki液化识别方法的可行性,特别是对软土和液化场地的识别能力。选择包含了13个软土场地的52个场地实际地震纪录,分析结果表明,该方法识别成功率随场地类别变软而显著降低,对中硬、中软和软土非液化场地成功率分别为100%、70.6%和46.2%,对液化场地成功率为62%,对软土和液化场地会出现明显误判。方法中起控制作用的是平均瞬时频率MIF,能很好识别非液化的中硬场地,但难以区分软土场地和液化场地;混淆软土和液化场地的原因是采用平均瞬时频率MIF为绝对量,不符合液化对场地地震动影响的物理本质,建议采用相对量,可能会有好的效果。
