Data underlying the study of vertical drain method to improve soft soil using sand-filled perforated bamboos.

Data were collected to evaluate the performance of an eco-friendly, innovative vertical drain technique designed to improve soft soil using end-bearing, sand-filled perforated bamboo drains. Laboratory tests were conducted to determine the properties of the soil, sand, and perforated bamboo. The results are summarized in the given tables. Soft soil is idealized with modified Cam-Clay and sand is modified as Mohr-Coulomb constitutive model in the numerical analysis performed in the study.

本研究采集数据以评估一种环保型创新竖向排水技术的性能，该技术采用承压式填砂穿孔竹制排水板加固软土地基。为测定土料、砂料及穿孔竹材的物理力学特性，本研究开展了室内土工试验，试验结果汇总于本文所附表格中。在本研究开展的数值分析中，软土地基采用修正剑桥模型（Modified Cam-Clay）进行理想化模拟，砂料则采用摩尔-库伦本构模型（Mohr-Coulomb constitutive model）进行表征。
