随着我国公路事业的发展,公路的等级及线型标准越来越高,这样就不可避免地要在缓和曲线上修建斜交桥(涵)。由于路基边缘曲线方程与路中线缓和曲线方程并不一样,更由于超高加宽,使各点标高计算相当困难,而这些又必须在设计中予以解决。针对实际设计中的情况,笔者推导了有关计算公式,供同行在设计时参考。一、路基内外边缘曲线方程的推导
With the development of highway industry in our country, the grade and standard of highway are getting higher and higher, so it is inevitable to build a skewed bridge (culvert) on the easement curve. Because the embankment curve equation is not the same as that of the midline curve, it is quite difficult to calculate the elevation of each point because of the super widening. These problems must be solved in the design. For the actual design of the situation, I derived the calculation formula for reference in the design of their peers. First, the derivation of the curve equation inside and outside the embankment
