摘要
利用车载LiDAR测量和传统勘测方法分别对某高速公路改扩建项目初测和定测2个阶段进行路面勘测,通过高程精度、效率和安全保障投入3个方面的对比,提出高速公路改扩建路面勘测方法的建议。
By using mobile LiDAR survey and traditional survey methods,the road survey of a highway reconstruction and expansion project is carried out in two stages:preliminary survey and location survey.Through the comparison of elevation accuracy,efficiency and safety guarantee investment,the paper puts forward suggestions on the road survey methods of highway reconstruction and expansion.
