摘要
从互通立交互通范围内平面线形、主线纵断面线形、变速车道、平纵组合等角度分析平曲线半径数值参数对整个互通立交安全性的影响.选取贵州高速水唐互通立交线形设计项目作为案例,对互通立交线形设计项目平曲线半径参数的计算选择展开分析.通过实际案例分析可知,在对互通立交平曲线半径技术参数的数值开展计算与选择时,需在国家最新标准和规范要求下结合安全需求进行考量.
Abstract
Analyze the impact of numerical parameters of horizontal curve radius on the safety of the entire interchange from the per-spectives of horizontal alignment,mainline vertical section linearity,speed changing lanes,and horizontal and vertical combinations within the scope of interchanges.Selecting the Guizhou Expressway Shuitang Interchange Linear Design Project as a case study,analyze the calculation and selection of horizontal curve radius parameters for the interchange linear design project.Through practical case anal-ysis,it is known that when calculating and selecting the technical parameters of the horizontal curve radius of interchanges,it is neces-sary to consider safety requirements in conjunction with the latest national standards and regulations.
