The present investigation is on the behavior of coir geotextile-reinforced sandy soil foundations and to study the effect of different parameters contributing to their performance using laboratory model tests. The parameters investigated in this study included top layer spacing, number of reinforcement layers and vertical spacing between layers. The effect of coir geotextile reinforcement on the vertical stress distribution in the sand and the strain distribution along the reinforcement were also investigated. The test results established the potential benefit of using coir geotextile-reinforced sand foundations. The test results also showed that the reinforcement configuration/layout has a significant effect on the behavior of reinforced sand foundation. With two or more layers of reinforcement, the settlement can be reduced at all footing pressure levels. The inclusion of reinforcement can redistribute the applied footing load to a more uniform pattern, hence reducing the stress concentration, which will result reduced settlement.

循环荷载下层数对椰壳土工布增强砂的影响

目前的研究是对椰壳纤维土工织物加筋的砂土地基的性能，并使用实验室模型试验研究不同参数对其性能的影响。在这项研究中研究的参数包括顶层间距，增强层数和层之间的垂直间距。还研究了椰壳土工布加筋对砂土中垂直应力分布和沿加筋处的应变分布的影响。测试结果确定了使用椰壳土工布加筋砂基础的潜在好处。测试结果还表明，加固构造/布局对加固砂基础的性能有显着影响。经过两层或多层加固，可以在所有立足点的压力水平下减少沉降。包含钢筋可以将施加的基础荷载重新分配到更均匀的样式，从而减少应力集中，这将导致沉降减少。
