城市道路一般每500～800 m就有一个交叉口。为了行车的平顺、排水和美观等的需要,在交叉口范围内必须进行竖向设计。而交叉口竖向设计的计算工作量较大,一般交叉口约需计算300个设计标高点,甚至更多。若用手工计算,约需两天时间,且容易出错。为了解决这一问题,作者编制了一个计算设计标高点的计算机程序。从输入计算参数到打印成计算结果,只需4～5分钟时间。不仅大大提高了工作效率,也为提高设计质量创造了条件。
Urban roads generally have an intersection every 500 ~ 800 m. In order to smooth the traffic, drainage and aesthetic needs, vertical design must be carried out within the intersection. The vertical design of the intersection of the larger calculation workload, the general intersection about 300 points need to calculate the design elevation, or even more. If calculated manually, about two days, and error-prone. In order to solve this problem, the author has compiled a computer program to calculate the design elevation. From the input calculation parameters to print into the calculation results, just 4 to 5 minutes time. Not only greatly improve work efficiency, but also to create the conditions for improving the quality of the design.
