摘要
通过区间估计模型将定性与定量分析相结合,确定公路预算定额的综合扩大系数区间,以新疆公路养护预算定额中路基工程人工综合扩大系数为研究对象,最后确定新疆公路养护预算定额人工综合扩大系数的区间为(1.299,1.502),降低了人为制定区间的不确定性所带来的误差,并从理论与实践的角度对区间的科学性进行了论证,为公路定额的基础理论研究提供了科学依据.
By the combination between the qualitative and quantitative analysis in the interval estimation model,the synthetical expansion coefficient for the road budget qwota is determined, Xinjiang highway maintenance budget quota in the embankment project of comprehensive study for the expansion coefficient, and the Xinjiang highway maintenance budget of integrated ircxed interval for the expansion coefticient （ 1. 299,1. 502） are also studied, The development of the human range of uncertainty brought about by error is reduced. From the perspective in theory and practice, the scientific nature of the interval is demonstrated for the road fixed theoretical research, and this can provide a scientific basis.
