摘要
根据线路平面设计资料,结合文中提出的线形判断方法,推导任意里程点处切线方位角的计算式,通过实例验证计算式的准确性与实用性,为今后计算轨道几何状态参数提供依据,同时也为处理轨道平顺性检测数据提供算法。
It presents the main content of the design of the plane linear documents.Then according to the information in the design documents,combination of the line and mathematics knowledge,the tangent azimuth of any mileage point calculation formula is deduced on the design linear circuit.The calculation of this formula in this paper is practically verified which provides a basis for the calculation of the state of the track geometry parameters,and lays a theoretical basis for the calculation of testing data of the orbital comfort processed in the program.
