摘要
在线直接检测填筑料的碾压变形是连续控制压实中亟待解决的问题。本文以填筑料碾压变形为研究对象,建立了基于平面激光束的碾压变形在线测量方法和系统。该方法采用激光测距和关键点定位确定碾压相对变形。基于现场试验,分析了碾压相对变形的演变过程。该系统实现了碾压相对变形在线直接检测,得到了填筑料碾压相对变形规律,有利于推动填筑工程智能建造技术的实际应用。
Online direct detection of rolling deformation of fill material is an urgent problem to be solved in continuous compaction control.To study the deformation and its detection,this paper develops an online rolling deformation measurement method and constructs an application system based on the planar laser beam technology.The method uses laser ranging and key point location techniques to determine the relative deformation of rolling.The application system realizes the online direct detection of the relative deformation and obtains certain relative deformation rules for fill material rolling,which helps promote the practical application of intelligent construction technology in filling engineering.
