【摘要】 提出了利用切线趋近法计算直线和线路平行线交点坐标的方法,不仅适用缓和曲线段、卵形曲线段、复合形曲线段,而且也使用于直线段和圆曲线段,容易在CASIO-4500P或CASIO-4800计算器上编程,通过算例验证该方法收敛较快,施工现场测量作业人员容易掌握。更多还原

【Abstract】 This paper presents the method to calculate the coordinates of the intersection point of the straight line with the parallel to the central line by means of tangent approaching. It is not only applicable to mitigation curve, oval curve and reunite curve, but also applicable to straight line and circle curve. With this method, it is convenient to write the procedure on the calculator of CASIOfx-4500P or CASIOfx-4800P. Practical engineering example proves that with this method the astringency is quick and it is easy for the surveyor to grasp.更多还原
