CPT-Based Liquefaction Case Histories from Global Earthquakes: A Digital Dataset (Version 1)

This dataset contains 275 CPT-based liquefaction case histories from 21 globally distributed earthquakes. These data, or subsets of these data, have been analyzed in the literature and are provided here to replicate published results.These cases are sourced from existing studies, to include observations of manifestation severity, CPT soundings, and estimation of GWT depth and ground-motion IMs, as generally reported by original investigators. When available, recent refinements were adopted from the literature. The compiled, post-processed data is presented in a structure array (a single file), allowing researchers to easily access and analyze information pertinent to free-field liquefaction response (i.e., triggering and surface manifestation). Research opportunities using this data include, but are not limited to, the training or testing of new and existing liquefaction-prediction models. Information describing the contents and structure of the case-history data are provided in a ReadME document.

本数据集包含来自全球分布的21次地震的275份基于圆锥静力触探试验（Cone Penetration Test，CPT）的液化案例历史记录。这些数据及其子集已在既往文献中得到分析，本次发布该数据集旨在复现已发表的相关研究结果。本案例均源自已有研究，涵盖原始研究者通常报告的液化显现严重程度观测、圆锥静力触探探测数据、地下水位（Groundwater Table，GWT）深度估算结果以及地震动强度指标（Intensity Measures，IMs）等内容。若有公开可用的最新修正方案，本数据集亦将其纳入。经整理与后处理的数据以结构化数组（单个文件）的形式呈现，便于研究人员便捷获取并分析与自由场液化响应（即液化触发与地表显现）相关的各类信息。基于本数据集可开展的研究方向包括但不限于：训练或测试新型及现有液化预测模型。关于本案例历史数据的内容与结构说明，详见配套自述（ReadME）文档。
