1、 1 题目：四级公路标准设计和施工放样题目：四级公路标准设计和施工放样 摘要摘要 测量的工作包括内业和外业，本文主要阐述外业的内容，即施工放线。测量放样工 作应遵循从整体到局部的原则， 先进行控制测量， 再进行细部放样测量。 通过控制测量， 建立起平面控制点和高程控制点与工程构造物特征点之间的平面位置和高程的几何联 系。为使学生理解消化课堂教学测量放样的内容，巩固和加深课堂所学的理论知识，熟 练掌握施工放样的流程，本论文主要介绍了施工放样数据计算以及在各个路线段和结构 物中施工放样的方法，所以保证了学生在施工放样各个流程有一个准确的认识和工作。 关键词：施工放样关键词：施工放样 数据计算数据计
