A Database of Cone Penetration Tests from North America

This dataset contains 1839 cone penetration test (CPT) results from across North America. This is the second version of this dataset, at the same DOI, where the first version contained 984 CPTs. The CPT data herein were processed and standardized according to the procedure described in the README file, which also includes formatting and structure details. The data are provided in both Python and Matlab file formats. Each row/cell of the dataframe contains the information for one CPT test, including: the identification number (ID); geographic coordinates in WGS84; CPT data (qc, fs, and depth); groundwater table (gwt) depth; increment of change in depth below the ground surface corresponding to the CPT depth data; and the depth of pre-drill prior to CPT.
This collection of CPT data has multiple potential uses, including liquefaction hazard assessments and studies of subsurface variability, among others. The CPT profiles were sourced from various publicly available sources. References corresponding to each CPT source are provided in this repository.

本数据集收录了来自北美全境的1839组圆锥静力触探（Cone Penetration Test, CPT）实测结果。本数据集为第二版，与第一版共享同一数字对象唯一标识符（Digital Object Identifier, DOI），初代数据集共包含984组CPT测试数据。本次收录的CPT数据已按照README文件中所述流程完成处理与标准化，该文件同时提供了数据格式与结构细节说明。数据以Python和Matlab两种文件格式提供。数据框的每一行/每一列均对应一组CPT测试的完整信息，包括：测试标识号（ID）、WGS84坐标系下的地理坐标、CPT实测数据（锥尖阻力qc、侧壁摩阻力fs与测试深度）、地下水位（groundwater table, GWT）埋深、对应CPT深度数据的地表下深度变化增量，以及CPT测试前的预钻深度。该批CPT数据集具备多项潜在应用场景，包括液化灾害危险性评估、地下变异性研究等。本批CPT剖面数据来源于多个公开数据源，每个CPT来源对应的参考文献均已在本数据集仓库中提供。
