摘　　要：边坡施工期的变形监测是实现边坡安全监控、预防边坡失稳的重要手段。现依托杭绍台高速公路K157岩质高边坡的工程实践,讨论了三维激光扫描的测试原理与数据采集方式,采用三维激光扫描技术对边坡的施工期进行监测,获得边坡不同阶段的变形规律,与GNSS监测进行对比,为边坡稳定性的评价提供精准、可靠的数据。其成功应用表明,这是一种科学、高效的边坡监测手段。Deformation monitoring of slope construction is an important means to realize slope safety monitoring and prevent slope instability.Based on the engineering practice of K157 high rock slope of Hangzhou-Shaoxing-Taizhou highway,this paper discussed the test principles and data collection method of 3D laser scanning,application in the construction period of slope with 3D laser scanning technology.By obtaining the deformation law of slope in different stages and comparing with GNSS,accurate and reliable data for the evaluation of slope stability was provided.The successful application proved that it was an scientific and efficient means.
