线路测量反算在施工放样中的应用

Line survey inverse calculation application in the setting out for highway construction

结合传统线路的放样方法不能适应现代施工技术和标准要求的现状,介绍了线路测量反算法在施工放样中应用的原理和步骤,并给出了CASIO fx-4800里程偏距反算程序,以解决传统圆曲线和缓和曲线放样中累计误差大、精度低、效率不高等问题。

Combined with the present situation that the classical line setting out methods can not adapt the modem construction technology and standard requirement, the principle and procedure of line survey inverse operating application in the setting out for highway construction were introduced. The inverse calculation process of CASIO fx-4800 milestone offset distance was proposed to resolve large accumulating error, low precision and efficiency in the classical circular curve and gentle curve setting out methods.
