Abstract

Abstract Re-using waste generated from daily domestic usage to improve weak soils such as dune sand gives a profitable solution to both environment and the construction sector. In this paper, weak sandy soil was modified with two types of fibers derived from daily domestic use. Plastic bottle waste fiber and tainted polypropylene sediment filter fiber were embedded in the sandy soil with a rate of (0.5%,1%,1.5%, and 2%) by weight of dry soil. Toward this, the direct shear test was conducted to confirm the optimum fiber content and evaluate other parameters such as shear strength, normalized ultimate shear strength, angle of internal friction, and adhesion. The results showed that the 1.5% fiber content showed higher values of angle of internal friction and the normalized ultimate shear strength for both types of fibers. The reinforcement with plastic bottle waste fiber and tainted polypropylene sediment filter fiber enhanced the shear strength parameters and normalized ultimate shear strength. Significant improvement was noticed in the adhesion value with the addition of 2% of tainted polypropylene sediment filter fiber. finally, the effect of fiber addition on the Mohr-coulomb failure envelope was discussed.

利用工业废料作为土工纤维加固沙土的可行性

摘要重新利用日常生活中产生的废物来改良沙丘沙等薄弱土壤，为环境和建筑行业提供了一个有利可图的解决方案。在本文中，使用了两种从日常生活用品中提取的纤维来改良薄弱的沙质土壤。塑料瓶废纤维和玷污聚丙烯沉积物过滤纤维分别以干土重量的 0.5%、1%、1.5% 和 2% 的比例嵌入砂土中。为此，进行了直接剪切试验，以确定最佳纤维含量，并评估剪切强度、归一化极限剪切强度、内摩擦角和附着力等其他参数。结果表明，纤维含量为 1.5%时，两种纤维的内摩擦角和归一化极限剪切强度值都较高。使用塑料瓶废纤维和玷污聚丙烯沉积物过滤纤维进行增强后，剪切强度参数和归一化极限剪切强度均有所提高。最后，讨论了纤维添加对莫尔-库仑失效包络的影响。
