土工格栅在路基加筋工程和挡土墙以及边坡工程中得到广泛应用,成为工程中不可缺少的一种工程材料,但是目前对土工格栅测试中格栅条数对格栅力学和变形性能的影响和碾压前后格栅力学特性没有详细的阐述。文章结合现场碾压试验,具体分析了条数和碾压对格栅性能的影响。研究结果表明碾压和格栅条数对格栅性能有重要影响,在格栅设计中应引起重视。
Geogrids are widely used in reinforced subgrade projects and retaining walls as well as in slope engineering and have become an indispensable engineering material in engineering projects. However, the number of grids in geogrid testing is currently critical to grid mechanics and deformation The influence of the performance and the mechanics of the grille before and after rolling are not explained in detail. Combined with the field rolling test, the article analyzes the influence of the number and rolling on the performance of the grille. The results show that rolling and the number of grids have an important influence on the grid performance, which should be paid more attention to in the grid design.
