Liquefaction database (LIQ/7/2833)

A comprehensive global liquefaction database comprising 2833 historical records across 15 countries. Each record incorporates 6 soil parameters as well as 1 liquefaction indicator. The 6 soil parameters (including the ratio of overburden stress, normalized SPT blow number, normalized cone tip resistance, soil behavior index, normalized shear wave velocity, and fines content) cover three types of in-situ tests which are prevalent for liquefaction assessment. The liquefaction indicator parameter (denoted by L) indicates the liquefaction occurrence (i.e., L = 1 for a liquefaction record, and L = 0 for a non-liquefaction record). The seismic parameters such as moment magnitude (Mw) and peak ground acceleration (PGA) can be also found in the Excel file. The basic information of this database is summarized in the Supplementary Material.

本数据集为一套覆盖全球15个国家、包含2833条历史记录的综合性土液化数据库。每条记录均包含6项土体参数与1项液化判别指标。该6项土体参数分别为上覆应力比、标准贯入试验（Standard Penetration Test，SPT）击数归一化值、锥尖阻力归一化值、土性指数、剪切波速归一化值与细粒含量，覆盖了当前主流的三类用于液化判别的原位测试方法。该液化判别指标（记为L）用于表征液化发生状态：当L=1时代表该记录为液化案例，L=0时则代表非液化案例。该Excel文件中还包含矩震级（moment magnitude，Mw）、地面峰值加速度（Peak Ground Acceleration，PGA）等地震动参数。本数据库的基础信息汇总于补充材料中。
