为提高汽车在弯道上行驶的稳定性,以确保行车的安全、舒适,部颁81年《公路工程技术标准》(以下简称《标准》)规定各级公路的平曲线半径当小于《标准》限定的不设超高的最小半径(米)时,应在圆曲线段设置全超高,并在缓和曲线段内设置缓和超高。 In order to improve the driving stability of the car and ensure the safety and comfort of driving, the 81-year Highway Engineering Standards (hereinafter referred to as the “Standard”) stipulate that the horizontal curve radii of the roads at all levels should be smaller than the “standard” Of the minimum radius (m) is not set high, it should be set in the circular curve of all-super high, and ease the curve segment set to ease ultra-high.
