摘要
在现场施工放样时 ,经常遇到在曲线上的放样 ,特别是线路位于缓和曲线上时 ,计算更为繁杂。为此利用积分公式推导求出内外缓和曲线上点的计算方法 ,并借助CASIO fx45 0 0、CASIO fx480 0计算器编程来实现。实践证明该方法对于缓和曲线上放样具有快速、精确、简便和易于实现的优点。
Lofting on the curve is commonly meted in construction lofting. The computation is more complex when the route locates on easement curve. In this paper the computation method for the points on the easement curve is derived by integration formula and realized on the CASIO fx4500 and CASIO fx4800 calculators by programming. This method is fast, accurate and easy for the lofting on the easement curve verified by the practice.
