高速公路回旋线路基边桩测设

LAYOUT OF SIDE PILE ON ROADBED FOR CIRCLE ROUND LINE OF EXPRESSWAY

本文根据回旋线性质及公路各种线型特点，推导出以偏角法测设公路缓和曲线路基边桩所需参数——转角和距离，并以Ｃ语言编程实现这一计算过程，方便工程曲线测设。

Based on the property of the circle round line and the specialities of the different line type of the highway,the paper derives out the deflected angle and distance which are the required parameters for the layout of the side pile on the roadbed for the trasition cruve of the highway by using the deflection angle method.The calculation procedure is realized by using the C language programming, so that the layout of the engineering curve may be more convenient.
