The study examined the use of two different types of glass fibres – Alkali Resistant (AR) Glass Fibre and Electronic Grade (E) Glass Fibre as reinforcement in soils to improve its strength. Glass fibre reinforcement causes a marginal change in the plastic nature and compaction behaviour of the reinforced soil. Also, the addition of fibres renders the soil less sensitive to moisture changes. Fibre inclusion promotes ductile behaviour of reinforced soil. Unreinforced soil fails with distinct shear plane while reinforced soil shows multi-shear failure and bulging with a network of minor cracks bridged with fibres. The results of this study show that random inclusion of fibres improve the unconfined compressive strength of the reinforced soil and it’s energy absorption capacity. The optimum glass fibre content is observed to be 0.75% for both AR glass fibre and E glass fibre. AR glass fibre performs better than E glass fibre for all proportions of fibre inclusion investigated.

该研究检查了两种不同类型的玻璃纤维的使用——耐碱 (AR) 玻璃纤维和电子级 (E) 玻璃纤维作为土壤中的增强材料以提高其强度。玻璃纤维增​​强导致增强土壤的塑性和压实行为发生边际变化。此外，添加纤维使土壤对水分变化不那么敏感。纤维夹杂促进了加筋土的延展性。未加筋土以明显的剪切面破坏，而加筋土则显示多剪破坏和膨胀，并带有由纤维桥接的小裂缝网络。研究结果表明，纤维的随机掺入提高了加筋土的无侧限抗压强度和吸能能力。观察到最佳玻璃纤维含量为 0。AR 玻璃纤维和 E 玻璃纤维均为 75%。对于所研究的所有纤维夹杂物比例，AR 玻璃纤维的性能都优于 E 玻璃纤维。
