| 英文摘要 | Geosynthetics reinforced soil techniques are adopted to reinforce the calcareous sand foundations to improve the stability of the revetment structures in coral reefs. In this research, the influence of particle size distribution on the interaction characteristics of the geotextile/geogrid-calcareous sand (GT/GG-CS) and unreinforced calcareous sand (URCS) interface is investigated through a series of large-scale monotonic direct tests. The interface interaction mechanism of GT/GG-CS and URCS is determined. The results show that under different particle size distributions and normal stresses, the dilatation curves of the GT/GG-CS and URCS interface mainly show the development patterns of contraction-dilatation-contraction, contraction-dilatation, and contraction. Additionally, embedding geogrid/geotextile in calcareous sand can significantly improve peak cohesion. For coarsegrained calcareous sand, the peak cohesion increases by 3.68 times (Geogrid-calcareous sand interface) and 2.41 times (Geotextile-calcareous sand interface). Overall, using coarse-grained calcareous sand as filler improves the stability of dredger-fill calcareous sand foundations and revetment-reinforced soil engineering. |
