Abstract
The optimization of geotextile mechanical properties is crucial for enhancing their performance in civil engineering applications such as soil reinforcement and stabilization. This study focuses on the influence of manufacturing parameters on the static puncture (CBR) properties of polyester geotextiles. Polyester geotextile samples were manufactured using various parameters, including needle-punching density, penetration depth, calendering temperature, and speed. The mechanical properties of the samples, specifically strength and elongation, were evaluated using the CBR test according to EN ISO 12236. The data were analyzed using multivariate analysis of variance, followed by statistical analysis to determine the influence of the manufacturing parameters on the mechanical properties. Furthermore, the relationship between these parameters and the mechanical properties was modeled using artificial neural networks (ANN) and regression analysis. The results indicated that all manufacturing parameters significantly impacted the strength and elongation of the geotextiles. The ANN models, employing two hidden layers, predicted the strength and elongation with errors of 1.43% and 1.26%, respectively.
土工织物机械性能的优化对于提高其在土木工程应用(如土壤加固和稳定)中的性能至关重要。本研究的重点是生产参数对聚酯土工织物静态穿刺(CBR)性能的影响。聚酯土工织物样品的制造采用了不同的参数,包括针刺密度、穿透深度、压延温度和速度。根据 EN ISO 12236 标准,使用 CBR 试验评估了样品的机械性能,特别是强度和伸长率。使用多元方差分析对数据进行分析,然后进行统计分析,以确定生产参数对机械性能的影响。此外,还利用人工神经网络(ANN)和回归分析对这些参数与机械性能之间的关系进行了建模。结果表明,所有生产参数都会对土工织物的强度和伸长率产生重大影响。采用两个隐藏层的人工神经网络模型对强度和伸长率的预测误差分别为 1.43% 和 1.26%。
