随着我国经济建设的发展,大量高等级公路开始兴建,对公路线形的要求也相应提高。因此,新建改建公路大都要设置缓和曲线。对公路缓和曲线的计算和测设,在一般情况下,都可应用常规方法进行。但有时因受地形、地面障碍等因素影响,就不能按正常方法进行。为此,本文结合工程实例对几种障碍情况下的公路缓和曲线测设问题进行研讨,提出精确而简捷的计算方法,以供参考。
With the development of our country’s economic construction, a large number of high-grade highways have started to be built, and the demands on highway alignment have also been correspondingly raised. Therefore, most of the newly built roads should be set to ease the curve. Calculation and measurement of the easement curve of the highway can be carried out by conventional methods under normal circumstances. But sometimes due to terrain, ground obstacles and other factors, it can not be carried out in accordance with normal methods. To this end, this article with engineering examples of several obstacles in the case of the road curve measurement and design to discuss the issue, put forward accurate and simple calculation method for reference.
