随着经济的迅速发展,高速公路和城市道路的等级的越来越高,在很多交叉中均采用互通立交。除了在枢纽立交中,单喇叭、双喇叭的平面布置在立交设计中出现是最多的。而在单喇叭、双喇叭的线形中,卵形曲线是在平面布线不可缺少的线形之一。而卵形曲线在书本中提到的很少,下面我们通过道路设计软件维地hint5.6设计的线位和坐标,然后根据已知的设计参数,用手算出卵形曲线的任意桩号的坐标,从而探讨卵形曲线的坐标的计算,亦可验证道路设计软件维地hint5.6的正确性。
With the rapid economic development, the level of highways and urban roads is getting higher and higher, and interchanges are adopted in many intersections. In addition to the interchange in the hub, the layout of single speakers, dual speakers in the interchange design appears to be the most. In the single horn, double horn of the line, oval-shaped curve is one of the essential line in the plane wiring. The oval-shaped curve mentioned in the book is very small, the following we use the road design software to design lines and coordinates hint5.6, and then according to the known design parameters, by hand to calculate the oval-shaped curve of any station Coordinates, so as to explore the oval-shaped coordinates of the coordinates of the calculation, but also verify the accuracy of road design software to hint5.6.
