摘要
推导出缓和曲线加宽段路幅边缘线长度计算的数值积分表达式,指出现有文献计算公式错误之处,澄清了错误认识。给出了卡西欧fx-4800P计算器程序及步长自适应验证程序清单,结合工程实例,验证所推公式正确性。
The paper deduced the numerical integration calculation formula of widend sideline length for transition curve route and analysed the existent documents′error and shortage,then the the Casio-fx 4800p computer program、step-size proved program and engineering examples are also be given respectively.
