摘要
针对在特殊线位上的斜交涵洞采用一般简化几何模型进行涵长计算存在一定误差的问题,提出涵长的一种坐标电算法,可综合反映涵位所受平曲线曲率、竖曲线以及路基超高对涵长的影响。
Aiming at some error existed in length calculation for skew culverts at some special line location by use of the normal simplified geometrical models, this paper puts forward a new computerized coordinate method for calculating the culvert length, which can comprehensively reflect the impacts to the culvert length at its location by the horizontal curvature, vertical curve and subgrade superelevation.
