摘要
按照目前的规范标准进行公路设计时,一般路段与完全超高路段的合成坡度都能保证满足要求,而超高渐变段的合成坡度却往往被忽略,导致现有公路的积水路段多在弯道处,影响行车安全。为此,从理论上分析了合成坡度的计算方法和影响因素,并进行了合成坡度的应用分析。
When a highway is designed in accordance with the current specifications and standards, the synthetic slope of the general section and the full super-elevation section can all meet the requirements. But the synthetic slope of super-elevation transition section is ignored usually. As a result, the waterlogged sections of the existing highways are mostly at the curves, which affect the traffic safety. Therefore, the calculation method and influencing factors of the synthetic slope are analyzed theoretically, and the application of the synthetic slope is analyzed.
