摘要
当前以经验估计确定定额样本量的方法,已经完全不能满足广泛采用"四新"项目的公路隧道定额准确度的要求,通过确定原始资料的最佳样本量来提高定额编制的精确性和可信性。鉴于此,依托科研项目M省公路隧道工程补充预算定额的调查数据,引入改进统计模型,以JTG/TB 06-02—2007《公路工程预算定额》中定额项目的划分、子目的分类和工序的工作内容为前提,将公路隧道定额测定工序的最佳样本量分为3类研究。研究得到3类工序的最佳样本量,并且研究了最佳样本量的变化特征,为各地区确定隧道定额原始资料的样本量提供一定的参考借鉴。
The determination method of sample quantity of tunnel norm according to experience can not meet the new requirements of highway tunnel. The reliability of norm compilation can be improved by deciding the optimal sample quantity of original data. According to complementary budget norm of a highway tunnel and partition of norm items,classification of specific items and working items of construction processes in JTG / TB 06- 02—2007 Highway Engineering Budget Norm,the improved statistical model is brought in and the optimal sample quantity of determination process of highway tunnel norm is divided into 3 kinds. The optimal sample quantities and their variation characteristics of the 3 kinds of highway tunnel norm are obtained. The results can provide reference for determination of sample quantity of original data of tunnel norm in the future.
