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.本综合数据集由自动化模拟生成。输入参数包含三类：几何变量（软土层厚度d0、排水板长度d1、涂抹范围d7、塑料排水板（PVD）半径d8）、土体特性参数（修正压缩性指数λ*（d2）与κ*（d3）、水平渗透系数d4、涂抹区渗透系数d5）以及荷载条件（超载d6）。该数据集的主要输出为最终沉降量，记为Y。
