2010-2011年坎特伯雷地震序列始于2010年9月4日的Mw7.1达菲尔德地震，包括多达10个诱发液化的事件。最值得注意的是，广泛的液化是由达菲尔德和Mw6.2基督城地震。多个事件期间有充分记录的液化反应、密集记录的事件地面运动以及详细的地下特征描述的结合提供了前所未有的机会，可以将有充分记录的案例历史添加到液化数据库中。本文介绍并应用了50个高质量的静力锥贯入试验（CPT）液化的案例历史，以评估三种常用的，确定性的，基于CPT的简化液化评价程序。虽然所有程序都正确预测了大多数情况，但Idriss和Boulanger（2008）提出的程序导致分析的案例历史的最低误差指数，从而表明对观察到的液化反应的更好预测。
The 2010–2011 Canterbury earthquake sequence began with the 4 September 2010, Mw7.1 Darfield earthquake and includes up to ten events that induced liquefaction. Most notably, widespread liquefaction was induced by the Darfield and Mw6.2 Christchurch earthquakes. The combination of well-documented liquefaction response during multiple events, densely recorded ground motions for the events, and detailed subsurface characterization provides an unprecedented opportunity to add well-documented case histories to the liquefaction database. This paper presents and applies 50 high-quality cone penetration test (CPT) liquefaction case histories to evaluate three commonly used, deterministic, CPT-based simplified liquefaction evaluation procedures. While all the procedures predicted the majority of the cases correctly, the procedure proposed by Idriss and Boulanger (2008) results in the lowest error index for the case histories analyzed, thus indicating better predictions of the observed liquefaction response.
