激光扫描技术在三维地下工程测量中的应用研究

Application of Laser Scanning Technology in 3D Underground Engineering Survey

激光扫描是目前运用普遍的一种非接触式测量技术,该方法由于其自身的准确性和高效性被广泛运用在工程建设中。本文在论述激光扫描技术原理的基础上,结合地下隧道工程实例,分析了激光扫描技术在测量隧道变形中的运用,明确了隧道施工中超欠挖分布和数值,为地下工程中激光扫描技术的运用提供了参考。

Laser scanning is a non-contact measurement technology,which is widely used in engineering construction due to its accuracy and efficien-cy.On the basis of discussing the principle of laser scanning technology,this paper combines with the example of underground tunnel engineering,analyzes the application of laser scanning technology in measuring tunnel deformation,and clarifies the distribution and value of overbreak and un-derbreak in tunnel construction,which could provide reference for the application of laser scanning technology in underground engineering.
