道路缓和曲线加宽段内侧路幅面积的计算

摘要

Direct proportion and higher parabola widend transition methonds are often used in transition curve road,the inside road plane is irregular-shaped.The paper deduced the numerical integration calculation formula of widend inside plane area for transition curve road and calculated it in Casio-fx 4800p computer and simulated it by Excel and AutoCAD in computer.%道路缓和曲线加宽过渡段内侧路幅边线常采用比例法和高次抛物线法,加宽段内侧路幅为一非等宽异形平面,文章推导了其面积计算的数值积分公式,利用卡西欧fx-4800P计算器的数值积分计算功能计算其面积,并借助Excel和AutoCAD软件对计算结果进行了模拟验证。
