[摘要]以世茂深坑酒店工程為背景,詳細介紹了三維激光掃描技術在該工程復雜巖壁基礎可視化協(xié)同設計中的應用。首先,采用三維激光掃描儀對深坑進行掃描作業(yè),獲得深坑三維點云數(shù)據(jù)。然后,將處理好的點云數(shù)據(jù)建立深坑的三維模型。在此基礎上,結合建筑基礎三維模型進行可視化協(xié)同設計,包括承臺標高檢查、基礎承臺優(yōu)化設計、建筑結構與巖壁碰撞分析等。最后,利用巖壁的三維模型,進行土方量計算、有限元模型建立、等高線繪制等。從三維掃描到三維建模應用,實現(xiàn)了建筑主體與周圍巖壁環(huán)境的可視化協(xié)同設計,可及時發(fā)現(xiàn)問題,避免了重復與返工,節(jié)約了大量時間和成本。

Abstract:Based on the engineering of Shanghai Shi Mao Chasm Hotel, the application of 3D laser scanning technology in visual collaborative design of complex rock foundation was introduced in detail. Firstly, a 3D laser scanner was used to scan large chasm to get the point clouds data of the chasm. Secondly, the point clouds were used to establish 3D model of the chasm. Visual collaborative design was taken using the 3D model of the building foundation, including the cushion cap elevation inspection, the optimization design of foundation cushion cap and the impact analysis of the building structure and rock. Lastly, the 3D model of the rock was used to calculate the quantity of soil, establish the finite element model, and draw the contour. 3D scanning and 3D modeling application could realize the visual collaborative design between the main building and the surrounding rock environment, to discover problems in time and avoid needless duplication and reworking. In this way, it saved a lot of time and cost.
Keywords:3D laser scanning technology; visual collaborative design; complex rock foundation; reverse remodeling; point cloud data
