In this study, the experimental investigation of model footing on crusher dust as an alternate granular soil with geotextile and geogrid as reinforcement is discussed. The experimental investigations were made separately with geotextile and geogrid with one to three layers in model tests at different relative densities. The bearing capacity was obtained from the load-settlement curve using the double-tangent method. The experimental results were validated through finite element analysis using commercial software Plaxis 3D. The friction between reinforcement and crusher dust is more than compared to that of natural sand, which may be due to surface roughness of crusher dust. The variations in bearing capacity of footing on geotextile and geogrid at different relative densities are compared in terms of bearing capacity factor Nγ. A parametric study was also presented in terms of variations of bearing capacity ratio of model and real-scale footing.

在这项研究中，讨论了以土工布和土工格栅为增强材料的破碎机粉尘作为替代颗粒状土壤的模型基础的实验研究。在具有不同相对密度的模型测试中，土工织物和土工格栅分别进行了一层至三层的实验研究。使用双切线法从载荷-沉降曲线获得承载力。使用商用软件Plaxis 3D通过有限元分析验证了实验结果。与天然砂相比，增强材料和破碎机粉尘之间的摩擦力更大，这可能是由于破碎机粉尘的表面粗糙度所致。比较了土工布和土工格栅在不同相对密度下的基础承载力的变化，以承载力系数Nγ进行比较。
