【摘要】：建筑的多样化需求带来建筑形象、功能的不断革新与增加,设计工作日益复杂、繁琐。而且,随着社会的发展,更多的精力放在能源效率、环境影响等可持续发展方面,对建筑设计效率的要求越来越高。传统的二维设计模式已不能满足设计需要,存在众多的弊端。近年来,BIM的快速发展给建筑业带来了革命性影响,BIM数据共享的思想使得项目各方能够更好的交流和协调,显著提高了项目设计的效率,降低了设计与施工中的管线冲突发生的概率。但是,目前基于BIM的碰撞检测的应用程度不深,精确度不高,在管线密度和复杂性不断提高的前提下,对碰撞检测的效率提出了更高的要求。因此就针对于建筑施工领域提出了提出了本文研究课题——基于BIM的综合管线碰撞检测技术研究。本文首先对经典的基于空间分解和空间占用的碰撞检测算法进行梳理,为基于BIM的综合管线的碰撞检测技术研究做理论铺垫;其次,从综合管线碰撞检测模型的构建方法、具体项目的BIM模型规范方面详细论述及研究,构建基于BIM的综合管线碰撞检测三维模型;然后,对基于BIM的综合管线碰撞检测环境特点进行提炼,本文选定集成空间分解与包围盒的混合碰撞检测思路,并结合空间分解与包围盒的特征,提出了一种集成空间分解和轴对齐包围盒的混合高效的碰撞检测算法;最后,将提出的集成算法应用于地下库工程综合管线BIM三维模型上,进行验证性应用及分析。通过工程实例的测试和分析,该集成空间分解与轴对齐包围盒的混合碰撞检测算法的检测效率优于传统的轴对齐包围盒和包围球混合碰撞算法,且模型量越大,效率优势越明显。
[Abstract]:The diversified demands of architecture bring about the building image, the constant innovation and increase of function, the increasingly complex and complicated design work, and with the development of society, more energy is devoted to sustainable development, such as energy efficiency, environmental impact, etc. The traditional two-dimensional design mode can no longer meet the needs of the design. In recent years, the rapid development of BIM has brought a revolutionary impact to the construction industry. The idea of BIM data sharing has enabled the parties to communicate and coordinate better, and significantly improved the efficiency of project design. The probability of pipeline collision in design and construction is reduced. However, the application of collision detection based on BIM is not deep, and the accuracy is not high. Under the premise of increasing pipeline density and complexity, The efficiency of collision detection is required higher. Therefore, the research topic of this paper is put forward for the construction field of building, that is, the research of integrated pipeline collision detection technology based on BIM. Firstly, the classical collision detection technology based on space is proposed in this paper. The collision detection algorithms of interspace decomposition and space occupation are combed, It lays a theoretical foundation for the research of collision detection technology of integrated pipeline based on BIM. Secondly, it discusses and researches in detail from the construction method of integrated pipeline collision detection model and the specification of BIM model of specific project. The 3D model of integrated pipeline collision detection based on BIM is constructed. Then, the characteristics of integrated pipeline collision detection environment based on BIM are refined, and the idea of hybrid collision detection based on integrated space decomposition and bounding box is selected in this paper. Combined with the characteristics of spatial decomposition and bounding box, a hybrid and efficient collision detection algorithm for integrated spatial decomposition and axial alignment bounding box is proposed. Finally, the proposed integration algorithm is applied to the BIM 3D model of integrated pipeline in underground storage engineering. Through the test and analysis of engineering examples, the detection efficiency of the hybrid collision detection algorithm of the integrated space decomposition and axis alignment bounding box is better than that of the traditional hybrid collision algorithm of the axial alignment bounding box and the bounding sphere. The larger the model is, the more obvious the efficiency advantage is.
