【摘要】：建筑的多樣化需求帶來(lái)建筑形象、功能的不斷革新與增加,設(shè)計(jì)工作日益復(fù)雜、繁瑣。而且,隨著社會(huì)的發(fā)展,更多的精力放在能源效率、環(huán)境影響等可持續(xù)發(fā)展方面,對(duì)建筑設(shè)計(jì)效率的要求越來(lái)越高。傳統(tǒng)的二維設(shè)計(jì)模式已不能滿足設(shè)計(jì)需要,存在眾多的弊端。近年來(lái),BIM的快速發(fā)展給建筑業(yè)帶來(lái)了革命性影響,BIM數(shù)據(jù)共享的思想使得項(xiàng)目各方能夠更好的交流和協(xié)調(diào),顯著提高了項(xiàng)目設(shè)計(jì)的效率,降低了設(shè)計(jì)與施工中的管線沖突發(fā)生的概率。但是,目前基于BIM的碰撞檢測(cè)的應(yīng)用程度不深,精確度不高,在管線密度和復(fù)雜性不斷提高的前提下,對(duì)碰撞檢測(cè)的效率提出了更高的要求。因此就針對(duì)于建筑施工領(lǐng)域提出了提出了本文研究課題——基于BIM的綜合管線碰撞檢測(cè)技術(shù)研究。本文首先對(duì)經(jīng)典的基于空間分解和空間占用的碰撞檢測(cè)算法進(jìn)行梳理,為基于BIM的綜合管線的碰撞檢測(cè)技術(shù)研究做理論鋪墊;其次,從綜合管線碰撞檢測(cè)模型的構(gòu)建方法、具體項(xiàng)目的BIM模型規(guī)范方面詳細(xì)論述及研究,構(gòu)建基于BIM的綜合管線碰撞檢測(cè)三維模型;然后,對(duì)基于BIM的綜合管線碰撞檢測(cè)環(huán)境特點(diǎn)進(jìn)行提煉,本文選定集成空間分解與包圍盒的混合碰撞檢測(cè)思路,并結(jié)合空間分解與包圍盒的特征,提出了一種集成空間分解和軸對(duì)齊包圍盒的混合高效的碰撞檢測(cè)算法;最后,將提出的集成算法應(yīng)用于地下庫(kù)工程綜合管線BIM三維模型上,進(jìn)行驗(yàn)證性應(yīng)用及分析。通過(guò)工程實(shí)例的測(cè)試和分析,該集成空間分解與軸對(duì)齊包圍盒的混合碰撞檢測(cè)算法的檢測(cè)效率優(yōu)于傳統(tǒng)的軸對(duì)齊包圍盒和包圍球混合碰撞算法,且模型量越大,效率優(yōu)勢(shì)越明顯。
[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.
