JS/SCPTU/372 Database

The JS/SCPTU/372 database covers 7 key parameters of Quaternary cohesive soils, including cone tip resistance (qt), sleeve friction (fs), pore water pressure (u2), shear wave velocity (Vs), overconsolidation ratio (OCR), sensitivity (St), and undrained shear strength (Su). This database contains 372 records, each representing a 1.0 m interval, compiled from 26 representative sites across Jiangsu Province, China. All entries include both high-quality in-situ SCPTU measurements and corresponding laboratory test results, with rigorous quality control following international standards. The JS/SCPTU/372 database provides a comprehensive and open-access dataset for investigating multivariate correlations among geotechnical parameters in soft, cohesive soils, supporting advances in data-driven site characterization and model development.JS/SCPTU/372数据库涵盖了第四纪黏性土的7项核心参数，具体包括锥尖阻力（cone tip resistance, qt）、侧壁摩阻力（sleeve friction, fs）、孔隙水压力（pore water pressure, u2）、剪切波速（shear wave velocity, Vs）、超固结比（overconsolidation ratio, OCR）、灵敏度（sensitivity, St）以及不排水抗剪强度（undrained shear strength, Su）。该数据集共计收录372组记录，每组对应1.0米的土层间隔，数据汇编自中国江苏省内26个典型勘察场地。所有数据条目均包含高质量的原位孔压静力触探（SCPTU）测试结果与对应的室内试验数据，且严格遵循国际标准完成了严谨的质量管控。JS/SCPTU/372数据库可为软黏性土岩土参数间的多变量相关性研究提供全面的开放获取数据集，为数据驱动的场地勘察与模型开发领域的研究进展提供有力支撑。
