BIM技术在山地城市基坑工程中的应用
摘要:以重庆市某具有山地典型地质条件特征的基坑工程为例,分析了BIM技术在该工程中的应用要点,提出了基坑工程三维建模流程;基于BIM软件Civil 3D和Revit为平台构建了基坑工程三维地质-设计耦合模型,进行了主体工程与临近建筑物基础的碰撞检查,实现了基坑工程三维展示、二维出图、统计算量等功能,并对施工过程进行了模拟。结果表明,基于BIM技术的三维可视化信息模型可以实现基坑工程地质条件和支护设计的精细化展示,对施工方案进行动态化描述,高效地解决了山地城市基坑工程岩土体分布不均、边坡类型及支挡结构多样、相邻建筑物基础冲突、施工工序交错繁杂等问题。
Abstract:A foundation pit in typical geological condition in mountainous area of Chongqing is analysed as an example. Key points of BIM application in the project is analysed and a three-dimensional modelling flow of foundation pit engineering is proposed. A three-dimensional geology-design coupling model of foundation pit is constructed based on BIM Civil 3D and Revit. Based on this model, the foundation collision check between the main object and the adjacent constructions is tested firstly. Then, three-dimensional display, two-dimensional drawing and statistical computation are established, separately. Finally, the construction process is simulated. The results show that the three-dimensional visualization model based on BIM can realize a fine demonstration of the geological condition and support design, and descript the construction plan dynamically. This model can effectively solve the problems in mountainous city foundation pit engineering, including the uneven distribution of rock and soil, a variety of slope type and retaining structure, adjacent building foundation conflict and the complex construction procedure.
