Prefabricated Vertical Drains (PVD) for Soft Ground Improvement

A comprehensive dataset was generated from an automated simulation. The input parameters consisted of geometric variables (soft soil thickness, d0; drain length, d1; smear extent, d7; PVD radius, d8), soil properties (modified compressibility indices λ*, d2 and κ*, d3; horizontal permeability, d4; smear zone permeability, d5), and loading conditions (surcharge, d6). The primary output was the final settlement, denoted as Y.

本数据集通过自动化模拟生成，属于综合数据集。其输入参数包含三类：几何变量包括软土层厚度（d0）、排水板长度（d1）、涂抹范围（d7）以及塑料排水板（PVD）半径（d8）；土性参数涵盖修正压缩指数λ*（d2）与κ*（d3）、水平渗透系数（d4）以及涂抹区渗透系数（d5）；加载条件为堆载（d6）。本数据集的主要输出为最终沉降，记为Y。
