《公路工程技术标准》(以下简称新标准)已于1981年5月由交通部正式颁发执行。本文的目的,是在学习新标准的基础上,对公路改建中有关线形设计的若干问题进行探讨。同时,对新旧《标准》中关于路线线形的各项主要技术指标进行比较,并对 “Highway Engineering Standard” (hereinafter referred to as the new standard) was in May 1981 by the Ministry of Communications officially issued. The purpose of this paper is to discuss some problems about the linear design in highway reconstruction on the basis of learning new standards. At the same time, the old and new “standards” on the line alignment of the major technical indicators are compared, and
