摘　　要：为确定不同条件下单向双车道立交匝道的加宽值,本文对比分析了中国、日本及美国规范中关于加宽值的计算思路,提出较为合理的单向双车道匝道加宽计算方法,并分析设计速度和曲线半径对加宽值的影响,对立交细则中Ⅱ型匝道加宽值进行了修正,使用仿真软件Vissim分析不同交通环境下行车道宽度对通行情况的影响,最后结合工程实践,详细介绍了加宽计算方法,可为单向双车道立交匝道路面加宽提供参考。In order to determine the widening value of one-way two-lane interchange ramps under different conditions,this paper compares and analyzes the calculation ideas of widening value in Chinese,Japanese and American specifications,puts forward a more reasonable calculation method of one-way two-lane ramp widening,analyzes the influence of design speed and curve radius on the widening value,modifies the widening value of type II ramp in Guidelines For Design of Highway Grade-Separated Intersections,uses the simulation software Vissim to analyze the traffic conditions of lane width in different traffic environments,and introduces the widening calculation in detail in combination with engineering practice.The analysis can provide a reference for pavement widening of one-way two-lane interchange ramps.
