摘要
因二维设计市政路桥耗时较长,研究基于“BIM+无人机”技术的市政路桥正向设计方法.依据无人机采集市政路桥设计区域地形影像数据,生成真实三维市政路桥设计区域地形模型;同时依据现场地质勘探结果,生成地质模型;在BIM的Bentley软件中直接导入三维市政路桥设计区域地形模型和地质模型实施线路平、纵设计,构建市政道路、桥梁、隧道等模型;经BIM模型总装后,通过碰撞检测实施设计校审,校审合理后完成市政路桥正向设计.实验结果表明:该方法可展现市政路桥正向设计的详细工程数量情况,对市政路桥项目施工起到重要指导作用。
Because the two-dimensional design of municipal roads and bridges takes a long time,the forward design method of municipal roads and bridges based on"BIM+UAV"technology is studied.According to the terrain image data of the municipal road and bridge design area collected by UAV,the real three-dimensional terrain model of the municipal road and bridge design area is generated;At the same time,the geological model is generated according to the results of field geological exploration;Directly import the 3D municipal road and bridge design area terrain model and geological model into the Bentley software of BIM to implement the horizontal and vertical design of the line,and build the municipal road,bridge,tunnel and other models;After the final assembly of the BIM model,the design review is carried out through collision detection,and the forward design of municipal roads and bridges is completed after the review is reasonable.The experimental results show that this method can show the detailed quantities of the forward design of municipal roads and bridges,and play an important role in guiding the construction of municipal roads and bridges.
