【摘要】 通过对互通式立交分流点曲率半径的一些影响因素进行分析,结合高速公路的勘察设计实践及有关文献,对分流点曲率半径的确定问题进行设计探讨,并给出横向力系数的取值表,绘出分流点所需的最小曲率半径图。最后对分流点行驶速度的采用、横向力系数的取值及分流点处匝道横坡设置提出几点建议,为今后互通式立交设计提供借鉴。更多还原

【Abstract】 This paper, based on the analysis of some influence factors of curvature radius at interchange diverting point and combined with express highway exploration and design practices as well as some documents, investigates the design of curvature radius at diverting point It also provides the table of transverse force coefficient and draws the minimum curvature radius graph that diverting points need Finally, a few suggestions have been put forward on the adoption of driving speed at diverting point, selection of transverse force coefficient and the setting of ring road and cross slope at diverting point It provides reference for the design of interchange in the future更多还原
