在公路常规勘测设计工作中,切线支距法是一种常用的中桩放样方法,但该方法以路线切线为基线,使用条件受到限制。该文介绍了公路测量导线的概念,提出了一种以公路测量导线为基线的支距法进行公路中桩放样。阐述了这种方法的原理和计算公式,并编制了应用于公路勘测的计算程序。
In routine survey and design of highway, tangent offset method is a commonly used stake setting method, but the method takes the route tangent as the baseline and the service conditions are limited. This paper introduces the concept of highway measuring lead and proposes a stake setting method based on the road measuring guideline as the baseline. The principle and calculation formula of this method are expounded, and the calculation program applied to highway survey is compiled.
