摘要
文中主要讨论了断面法及其延展方法在道路土方计算过程中的适用性,并以工程实例论述。从基础数据的采集精度、采集方法、特征点加密、特征点取舍等几方面进行论述,提出如何利用道路断面法对土方计算精度进行控制,并结合道路工程不同阶段的精度要求,最终给出工程各个阶段断面法取值范围。
Through engineering examples,this paper mainly discusses the applicability of section method and its extension in the calculation of road earthwork in terms of the acquisition accuracy of basic data,acquisition method,feature point encryption,and feature point selection.Considering the accuracy requirements of different stages of road engineering,the accuracy control of earthwork calculation by section method is proposed,in addition,the value range of each stage section method of the project is given.
