Experimental Study of Load and Settlement Behavior of Bamboo Grid Reinforced Sand
The tridirectional bamboo grid is a new innovative reinforcement of the limited life geotextiles (LLGs) family. It is more stable than the bidirectional bamboo grid and capable of transferring the stresses uniformly in all directions. Experimental studies of the pressure settlement behavior of single layer bamboo grid reinforced sand are introduced in this manuscript. Various laboratory model tests were performed to assess the bearing capacities of reinforced sand with the tridirectional bamboo grid and bidirectional bamboo grid. In the present study, static plate load tests were conducted in a steel tank (0.7 m×0.7 m×0.6 m) on non-reinforced and reinforced sand in the laboratory. The square model footing of size 100 mm×100 mm was used for all laboratory model tests. Two types of geogrids, namely bidirectional and a tridirectional bamboo grid made of a bamboo material of different aperture shape were utilized in the model testing. The effect of aperture shape and placement of bamboo grid at different depth ratios u/B on the bearing capacity of reinforced sand was investigated. The pressure settlement behavior of reinforced sand showed the placement of reinforcement beyond the zone of influence of depth ratio gives marginal improvement. The geometry of bamboo grid is more useful for improving the bearing capacity of reinforced sand. The experimental results indicate that the tridirectional bamboo grid provides better performance as compared to the bidirectional bamboo grid.
