摘　　要：基于现行的公路工程预算定额,分析不同公路工程构造中的应用案例,通过数据处理和对比分析法,找出影响工料机消耗的主次因素,定量分析生态自密实混凝土的经济效益。试验表明对比分析法能测算出单位体积的生态自密实混凝土技术施工的T梁比普通混凝土的定额直接费降低24%,护栏比普通混凝土的定额直接费降低18%,隧道二衬比普通混凝土的定额直接费降低15%。Based on the current highway engineering budget quota,this article analyzes the application cases in different highway engineering structures,identifies the primary and secondary factors that affect the consumption of materials and machinery through data processing and comparative analysis,and quantitatively analyzes the economic benefits of ecological self compacting concrete.The experiment shows that the comparative analysis method can measure and calculate the difference of direct cost per unit volume of ecological self-compacting concrete technology construction for T-beams,guardrails,and tunnel secondary-lining.The direct cost of T-beams is 24%lower than that of ordinary concrete.The direct cost of guardrails is 18%lower than that of ordinary concrete.The direct cost of tunnel secondary-lining is 15%lower than that of ordinary concrete.
