Abstract

The parameters concerning the interaction between geocell and granular materials is required for the design of many geotechnical structures. With this in mind, a series of experiments using simple direct shear tests are conducted in order to understand the frictional properties between geocells filled with granular materials. The 54 test samples are prepared by filling the geocell with granular materials having three different gradations. These samples are tested at three different relative densities under three different normal stress levels. As a result, it was observed that interface resistance between the geocells filled with granular material is found to be generally greater than in the samples without geocells. Additionally, these samples with geocells are found to be stiffer; this is due to the fact that the samples with geocell gained more cohesion because geocells confined the grains within a restricted volume.

填充颗粒材料的土工单元之间的摩擦特性

许多岩土工程结构的设计都需要与土工格室和颗粒材料之间的相互作用有关的参数。考虑到这一点，使用简单的直接剪切试验进行了一系列实验，以了解填充颗粒材料的土工格室之间的摩擦特性。54个试样是通过用具有三种不同级配的颗粒材料填充土工格室来制备的。这些样品在三种不同的法向应力水平下以三种不同相对密度进行测试。结果，观察到填充有颗粒材料的土工格室之间的界面阻力通常大于没有土工格的样品。此外，这些带有地质单元的样品被发现更坚硬；这是因为具有地质格室的样品获得了更多的内聚力，因为地质格室将晶粒限制在有限的体积内。

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
