摘要
为了研究废弃物加固路基土的力学性能,利用稻壳灰、建筑垃圾和石灰对黏土进行加固,测试废弃物在路基加固中再利用的可行性。结果表明,稻壳灰掺量为14%、或建筑垃圾掺量为26%或石灰掺量为6%时,黏土的自由膨胀率均可降至零。废弃物和石灰的混合使用可以提高黏土混合料的无侧限抗压强度和承载比,实现废弃物再利用。
In order to study the mechanical properties of waste reinforced roadbed soil,rice husk ash,construction waste,and lime are used to reinforce clay,and the feasibility of reusing waste in roadbed reinforcement is tested.The results show that when the content of rice husk ash is 14%,or the content of construction waste is 26%,or the content of lime is 6%,the free expansion rate of clay can all be reduced to zero.The mixed use of waste and lime can improve the unconfined compressive strength and bearing ratio of clay mixtures,achieving waste reuse.
