Abstract

Coarse-grained soil should be used as fill material for reinforced soil structures, but in engineering practice, sometimes people have to use fill material with high fine-grained content, which leads to problems of poor constructability, poor drainage, and excessive deformation of reinforced soil structures. In order to cope with this situation, a reinforced material with a drainage function is required, and drainage geogrid comes into being. Experimental research and engineering practice have shown that reinforced materials with a drainage function can quickly dissipate the over-pore pressure generated during the compaction construction of fine-grained soil and accelerate the consolidation of fill soil. Drainage geogrid can effectively drain and improve the structural stability of reinforced soil. The paper summarized the research results of reinforced materials with a drainage function and focused on the design method and engineering practice of reinforced soil structure of drainage geogrids. In view of the problems still faced at present, suggestions for further research on the reinforced soil structure of drainage geogrids were put forward.
