摘要
针对高速公路互通区匝道众多、线形复杂、对测量工作要求高的特点,根据曲线的特征,从转角计算着手,推导了两种半径变化较大的曲线坐标计算公式,再运用平面坐标体系转换,计算设计路线中心坐标及边桩,具有一定的参考价值。
According the features of interchange region in expressway with complicated ramp and line type, which has high specifications on measurement work coordinate calculation formula of two large-diameter curves are derived. Through transition of plane coordinate system the central coordinates and side pile of designed line are calculated, which has a certain references value for similar works.
