【摘要】 路基工程中经常采用向路基填料中掺入水泥、石灰(包括生石灰、熟石灰)等改良剂的方法来改良填料的性质以满足工程要求.由于水泥和石灰的物理化学性质不同,其作用效果也会有所差异.在分析水泥和石灰掺入路基填料后的作用机理的基础上,通过室内物理力学常规试验及室内重型击实试验,对比分析了这两种改良剂对路基填料的改良效果,并提出了合理的工程建议.更多还原

【Abstract】 Ameliorants,such as cement and lime,including quicklime and hydrated lime,are always used in the subgrade project to improve subgrade soil so as to meet project requirements.Because of their different physical and chemical properties,the effect of cement and lime will vary as well.This article,based on the analysis of the reaction process and mechanism of cement and lime after being added into subgrade filler,through indoor conventional physical and mechanical tests and indoor heavy compaction tests,comparatively analyzes the improvement results of these two kinds of subgrade filler,and then proposes reasonable project recommendations.更多还原
