摘　　要：为有效监测公路项目的施工进度,提出一种倾斜摄影技术与建筑信息模型(BIM)技术相结合监测公路项目施工进度的方法。首先基于倾斜摄影技术快速采集施工现场的信息数据,构建三维实景模型,并结合施工进度计划表进行施工模拟,构建项目计划进度BIM模型;然后基于平台开发施工进度分析插件,通过布尔算法实现三维实景模型与BIM模型的匹配切分和计算,得到施工进度报表;对比报表信息与项目计划进度BIM模型,直观了解施工进度偏差;最后计算边坡土方量,对计算结果进行精度分析,为控制边坡开挖进度提供重要依据。以广西平南高速公路项目为应用实例进行验证,结果表明:利用本方法可对公路施工进度进行定期监测,为施工进度监测提供新的方法;施工进度分析插件总体匹配精度为97.27%;通过对非地面点进行修正,在一定程度上提高了土方计算精度,得到的土方计算结果与施工记录结果差值比为2.05%。To effectively monitor the construction progress of highway projects,a method of monitoring the construction progress of highway projects by combining oblique photography and BIM technology was proposed.Firstly,a 3D real scene model was constructed by quickly collecting the information data of the construction site based on the oblique photography technique.Then the project schedule BIM model was obtained by constructing a BIM model based on the BIM technology and carrying out the construction simulation with the construction schedule.Secondly,a construction progress analysis plug-in was developed on the platform and the matching,segmentation and calculation of the 3D real scene model and BIM model were realized through Boolean algorithm to obtain the construction progress sheet,which was compared with the project schedule BIM model to intuitively understand the construction schedule deviation.The slope earthwork volume was calculated and the accuracy of the calculation results was analyzed to provide an important basis for controlling the slope excavation progress.The proposed method was experimented by taking the Pingnan expressway project in Guangxi as an example.The results show that this method can be used to monitor the highway construction progress regularly and provide a new method for the construction progress monitoring.The overall matching accuracy of the construction progress analysis plug-in is 97.27%.By correcting the non-ground points,the accuracy of earthwork calculation is improved to a certain extent and the difference ratio between the earthwork calculation result and the construction record result is 2.05%.
