【摘要】：施工场地布置是项目施工组织设计的重要内容，也是项目施工的前提和基础。合理科学的场地布置方案能够降低项目成本，确保工期，减少安全隐患，最终支撑项目目标的实现。场地布置方案的设计应当是项目管理的重要一环，但目前很多项目上，施工组织设计中的场地布置方案只是摆设，并没对现场的布置起到应有的指导作用，施工场地布置方案未得到足够重视。究其原因，主要有两点，，一是以往的场地布置方案基本都是静态的，但是施工现场的情况是动态变化的，对各类资源的需求也在不断变化，静态的场地布置方案不能满足动态施工的要求；二是项目通常只设计一种场地布置方案，方案单一，缺乏比选，难以判断其优劣。针对静态施工场地布置不符合动态施工需求的问题，论文提出施工场地动态布置的思路。本论文中的动态布置是指针对施工项目地基基础、主体结构和装饰装修三个不同阶段各自不同的施工特征及资源需求特征，分别设计其场地布置方案，达到用多阶段静态布置实现相对动态布置的目的。针对方案单一，缺乏比选的问题，研究提出从施工场地布置方案对施工管理和项目销售两个方面的影响出发，综合考虑承包方和业主方对场地布置的需求，完善评价指标体系，运用改进的灰色关联度分析法对施工场地布置方案进行评选。在方案评选指标体系中，本论文增加了在二维设计模式下难以量化的空间安全冲突指标，重点研究了运用BIM，建立建筑施工场地三维模型，通过动态施工模拟以及冲突检测，对空间安全冲突指标进行量化。希望通过本论文提供一种便于动态场地布置方案评选的方法，使施工场地布置方案更好的服务于建设项目。在理论研究上，论文中提出对场地进行动态布置，为施工场地布置研究提供一个新的角度，而且论文中对于研究BIM在场地布置中的应用，也为BIM的研究以及其在实践中的推广有一定意义。
[Abstract]:The construction site layout is an important content of the project construction organization design, and also the premise and basis of the construction of the project. The reasonable site layout scheme can reduce the project cost, to ensure the construction period, reduce security risks, to achieve the ultimate goal of supporting the project. Site layout plan design is an important part of project management, but at present a lot of projects on site layout construction organization design in just decoration, and not to the guiding role of the layout of the site, the construction site layout of the program did not get enough attention. The reason mainly has two points, one is the basic site layout plan is static, but the construction site is dynamic the change of the demand for various types of resources are constantly changing, can not meet the site layout scheme of static dynamic construction requirements; two is usually only a field layout design The case, the scheme is single, the lack of comparison, it is difficult to judge its advantages and disadvantages.
In the static layout of construction site does not meet the needs of the dynamic construction, proposed construction site dynamic layout ideas. Dynamic layout in this paper is based on the pointer construction project foundation, construction characteristics and resource demand characteristics of the main structure and decoration of three different stages of different, respectively design the site layout plan, achieve multi stage static layout relative dynamic arrangement. For single, lack of selection problems of two aspects from the construction site layout plan of construction management and project sales of demand comprehensive consideration of the contractor and the owner of the site layout, improve the evaluation index system, using the improved grey correlation degree the analysis on the selection of construction site layout plan. In the project evaluation index system, this paper adds in the two-dimensional design mode to Quantifying the spatial security conflict index, we focus on building the 3D model of construction site by using BIM, and quantify the spatial security conflict indicators through dynamic construction simulation and conflict detection.
To provide a method for dynamic site layout scheme selection in this paper, the construction site layout plan to better serve the construction project. In theory, the dynamic layout of the site, on the construction site layout to provide a new angle, and the thesis for the study of BIM in site layout the application of BIM for the study and promotion in practice has a certain significance.
