高速公路路线设计指标及安全性评价分析

DesignIndex and Safety Evaluation Analysis of Expressway Route

高速公路线形组合的优劣会直接影响整个公路工程设计和运营质量。鉴于此,首先总结了高速公路平面线形和纵断面设计的主要指标及基本要求,随后分析了平面线形组合、纵断面线形组合、及平纵组合的方法,最后基于济宁至商丘高速公路设计实例,分析确定了相关技术指标。

The quality of Expressway Alignment combination will directly affect the whole highway engineering design and operation quality.In view of this,this paper first summarizes the main indicators and basic requirements of Expressway plane alignment and profile design,then analyzes the methods of plane alignment combination,profile alignment combination and plane and profile combination,and finally analyzes and determines the relevant technical indicators based on an expressway design example in Shandong Province.
