摘要
为研究不同水泥和石灰掺量对过湿粘土路基性能的影响,本文结合试验路段采用不同水泥和石灰掺量进行过湿粘土路基改良施工,检测其液限、塑限、塑性指数,研究结果表明:随着水泥、石灰掺量增加土样液限和塑性指数减少而塑限逐渐增加;水泥改良粘土效果优于石灰改良,石灰经济性优于水泥;确定最佳水泥掺量为8%,最佳石灰掺量为6%。
In order to study the influence of different cement and lime contents on the performance of over-wet clay subgrade,it is combined with the test section by using different cement and lime contents to improve the construction of over-wet clay subgrade,to detect its liquid limit,plastic limit and plastic index.The results show that with the increase of cement and lime content,the liquid limit and plastic index of soil sample decrease and the plastic limit gradually increases.The improvement effect of cement on clay is better than that of lime,and the economy of lime is better than that of cement.The optimum cement content was determined to be 8%and the optimum lime content to be 6%.
