摘要
由于平面形式为弧形(半径较大)的建筑物一直是放线工程中的难点,通过对机场专用高速公路收费中心工程具体放线过程的详细论述,总结出对于弧形建筑物的放线宜将弧形轴线上的点将其极坐标的形式转化为平面直角坐标,并在放线的过程中灵活地将两者有机地结合起来。相互验证。
It is a difficulty to draw arc line of arc building plane in engineering. Tliis paper states a drawing line process of tlie charging center of airport highroad engineering, and summarizes that it is better for a point s coordinate from polar coordinate to change into right angle coordinate of arc building plane , combine two kinds of coordinate neatly and validate each other.
