【摘要】:伴隨著我國(guó)城市化進(jìn)程的高速發(fā)展,固定資產(chǎn)的投資規(guī)模迅猛增漲,由此帶動(dòng)了建筑業(yè)的跨越式發(fā)展。超高層、大跨度結(jié)構(gòu)的不斷涌現(xiàn),建筑結(jié)構(gòu)與建筑造型越來越復(fù)雜,各種復(fù)雜曲面在建筑上的應(yīng)用越來越多,這時(shí),以二維方式表現(xiàn)的施工圖由于可視化不強(qiáng),對(duì)圖紙的理解增加了不少的難度,建筑、結(jié)構(gòu)、設(shè)備各專業(yè)的設(shè)計(jì)師之間,設(shè)計(jì)師與建造師之間的交流也會(huì)產(chǎn)生一定的障礙。同時(shí),由于這些建筑的施工過程相當(dāng)復(fù)雜,傳統(tǒng)的施工方法和模式已經(jīng)無法滿足其要求,需要運(yùn)用計(jì)算機(jī)技術(shù)、網(wǎng)絡(luò)技術(shù)、虛擬現(xiàn)實(shí)技術(shù)、多媒體技術(shù)、三維數(shù)字技術(shù),構(gòu)建貫穿決策期、實(shí)施期、運(yùn)營(yíng)期的計(jì)算機(jī)管理系統(tǒng),實(shí)現(xiàn)設(shè)計(jì)與施工方案的優(yōu)化、施工過程動(dòng)態(tài)模擬與虛擬施工、建設(shè)全過程信息共享。作為國(guó)民經(jīng)濟(jì)支柱產(chǎn)業(yè)的建筑業(yè)的信息化水平不斷提高。在“十二五”期間,建設(shè)主管部門提出了“全面提高建筑行業(yè)信息化,推廣BIM技術(shù)在行業(yè)中的應(yīng)用”的要求。BIM(Building Information Modelii g——建筑信息模型)技術(shù)是使用數(shù)字化的表示方式,以三維數(shù)字技術(shù)為基礎(chǔ),集成工程項(xiàng)目的相關(guān)數(shù)據(jù),并以此為基礎(chǔ)進(jìn)行設(shè)計(jì)、建造和運(yùn)營(yíng)管理。通過運(yùn)用BIM技術(shù),可以促進(jìn)項(xiàng)目建設(shè)周期內(nèi)各階段的知識(shí)共享,采用分布式模型,以數(shù)據(jù)庫(kù)代替繪圖,將設(shè)計(jì)、施工和運(yùn)營(yíng)融為一體。它正在引發(fā)工程建設(shè)行業(yè)一次史無前例的徹底變革,并給采用該模型的建筑企業(yè)帶來極大的新增價(jià)值。施工方案的選擇與優(yōu)化是施工組織設(shè)計(jì)的核心,對(duì)工程施工具有指導(dǎo)性作用。施工方案的優(yōu)化包括施工程序、施工順序、施工方法的優(yōu)化和方案指標(biāo)(進(jìn)度、質(zhì)量、安全和成本等)的優(yōu)化。本文以BIM技術(shù)為基礎(chǔ),通過引入虛擬施工的概念,將BIM技術(shù)與虛擬施工結(jié)合在一起,用Revit系列三維建模軟件和NavisWorks模擬施工軟件進(jìn)行3D建模,并通過相關(guān)的信息模型從可視化協(xié)助施工和碰撞檢測(cè)這兩個(gè)角度進(jìn)行施工方案進(jìn)行分析與研究,并且加入時(shí)間維度進(jìn)行4維虛擬建造,形象的展示了施工的全過程。同時(shí),本文通過引入灰局勢(shì)決策模型和灰關(guān)聯(lián)模型對(duì)量化的施工方案指標(biāo)進(jìn)行優(yōu)化,通過模型的對(duì)比得出最優(yōu)的施工方案。使用基于灰色系統(tǒng)的改進(jìn)型工期計(jì)劃PERT模型對(duì)計(jì)劃工期進(jìn)行一步的優(yōu)化。
[Abstract]:With the rapid development of urbanization in China, the scale of investment in fixed assets is increasing rapidly, which leads to the leapfrog development of the construction industry. With the continuous emergence of super-tall buildings and long-span structures, the building structure and architectural modeling become more and more complex, and various complex surfaces are applied more and more in architecture. At this time, the construction drawings expressed in two dimensions are not visualized. Understanding of drawings has increased the difficulty, architecture, structure, equipment between the various professional designers, designers and architects of the communication will also create certain obstacles. At the same time, because the construction process of these buildings is quite complex, the traditional construction methods and models can no longer meet its requirements. It is necessary to use computer technology, network technology, virtual reality technology, multimedia technology, three-dimensional digital technology. The computer management system which runs through the decision-making period, the implementation period and the operation period is constructed to realize the optimization of the design and construction scheme, the dynamic simulation and virtual construction of the construction process, and the sharing of information in the whole construction process. As the pillar industry of the national economy, the information level of the construction industry has been continuously improved. During the 12th Five-Year Plan period, the construction department put forward the requirement of "improving the informatization of the construction industry in an all-round way and popularizing the application of BIM technology in the industry". Based on 3D digital technology, the data of engineering project are integrated, and the design, construction and operation management are carried out. By using BIM technology, we can promote the sharing of knowledge in each stage of the project construction cycle, adopt distributed model, replace drawing with database, and integrate design, construction and operation into one body. It is leading to an unprecedented revolution in the engineering construction industry and bringing great new value to the construction enterprises adopting the model. The selection and optimization of construction scheme is the core of construction organization design. The optimization of the construction scheme includes the optimization of the construction procedure, the sequence of construction, the optimization of the construction method and the optimization of the project index (schedule, quality, safety, cost, etc.). Based on BIM technology, this paper introduces the concept of virtual construction, combines BIM technology with virtual construction, and makes 3D modeling with Revit series 3D modeling software and NavisWorks simulation construction software. Through the relevant information model, the construction scheme is analyzed and studied from the two angles of visual construction and collision detection, and the four-dimensional virtual construction is carried out by adding the time dimension, which shows the whole process of construction graphically. At the same time, the grey situation decision model and grey correlation model are introduced to optimize the quantitative construction project index, and the optimal construction scheme is obtained by comparing the models. The improved PERT model based on grey system is used to optimize the schedule.
