Abstract: This paper introduced the application of baseline offset method used on the field layoul in mountain highway plane curve

Key words: baseline offset method, mountain highway, plane curve, field layout

摘要： 山区植被茂密，视线不通，基线支距法利用公路平曲线的虚交基线进行测设，可以有效地减少砍通视线工作量，提高测设速度。笔者通过与切线支距法和偏角法的比较，阐述了基线支距法的方便实用性。并介绍了利用 CASIOfx-4500P编辑计算器编程计算的方法。该法可用于带缓和曲线的不对称曲线测设，并通用于切线支距法、偏角法(极坐标法)。
