This Data in Brief article provides summarized information of the liquefaction case histories from the 12 May 2008 7.9 Wenchuan earthquake. According to the data processing procedures recommended in the related research article, all eighty-one case histories investigated by the present authors and seven other case histories from the literature are carefully compiled. All necessary information and the mean and standard deviation for some key parameters are given for these liquefaction case histories (i.e., site name, site location, site inclination angle, liquefaction manifestations, critical layer, soil sampling information, ground motion, total and effective stresses, shear-mass participation parameter, cyclic stress ratio (CSR) for =7.5, normalized shear wave velocity ( ), data class and field testing time). These data may be used by colleagues to study the effect of gravel content on liquefaction behaviour of gravelly soils and develop the corresponding deterministic or probabilistic methods for liquefaction triggering evaluation.
本数据简报文章提供了2008年5月12日汶川7.9级地震液化案例的汇总信息。根据相关研究文章推荐的数据处理程序，精心汇编了作者调查的所有81个案例以及文献中的其他7个案例。给出了这些液化案例的所有必要信息以及一些关键参数的均值和标准差（即场地名称、场地位置、场地倾斜角、液化表现、关键层、土壤采样信息、地面运动、总应力和有效应力、剪切质量参与参数、 =7.5时的循环应力比（CSR）、归一化剪切波速度（ ）、数据类别和现场测试时间）。这些数据可供同行研究砾石含量对砾石土液化特性的影响，并开发相应的确定性或概率性液化触发评估方法。
