【摘要】：近年来,为了使航空运输网更加完善,国家大力开展机场的基础设施建设。在机场工程施工项目管理中迫切需要规范项目管理的方法和手段,编制适宜的施工组织设计方案。因此,一方面需要开展如何保证工程施工质量、加快工程施工进度、节约工程施工成本的研究,另一方面需要明确施工组织设计优化的理论和方法,在工程实践中挖掘理论,在理论基础上进一步指导实践,逐步形成针对不同施工背景和条件下的施工组织优化设计理论和方案。但是现阶段针对机场工程项目的施工组织设计优化的研究较少,缺少配套的可以直接指导施工组织设计方案优化的理论和相关技术研究成果。本文以萧山机场飞行区二期扩建工程地基处理和土石方工程二标段为工程背景,研究了针对机场飞行区地基处理工程的施工组织设计及优化方法,主要取得了以下研究结论： (1)分析了施工组织设计在工程施工中发挥的重要作用和对施工项目成本、进度、质量的影响。探究了施工组织设计相关理论和优化方法,提出施工组织三要素“成本、质量、工期”的控制方法。首先,通过价值工程理论研究了施工组织设计中对施工成本进行控制和优化的方法,提出了价值指数的概念以及通过价值指数来评价施工方案优劣的方法；其次,将网络计划技术运用的施工工期的控制和优化中,将模糊层析分析法运用于施工方案的优选中,选择合理的施工工期控制方法和施工方案；最后,基于成本、工期和质量控制方法提出了多目标的施工方案综合优选的理论和方法,使得施工组织设计方案能够使得工期——费用——质量得到均衡控制和优化。研究成果将为实际工程中施工组织设计的优化提供理论依据。 (2)以杭州萧山国际机场二期扩建工程飞行区地基工程施工为实际工程背景,结合施工组织设计的理论和方法,对机场飞行区地基工程施工组织优化设计进行了研究。提出了施工总体部署、施工现场平面布置、施工进度控制和施工质量控制的一系列措施。分析了施工现场平面布置应考虑的因素和原则,对机场飞行区地基处理和土方工程二标段做出了适宜的施工平面布置方案；运用施工进度控制方法对机场飞行区地基处理和土方工程二标段的施工进度计划进行合理规划,提出了施工进度计划横道图；结合实际工点的施工特殊性,提出了保证施工质量的控制措施。 (3)针对地基处理和土方工程,从施工方法和施工技术的层面提出了实施方案。对土方工程施工技术、沟河塘处理工程施工技术、强夯法地基处理施工技术、以及填实碾压工程施工技术展开了研究,提出了运用模糊层次分析法进行施工方案比选的操作过程。对各专项工程的施工工序、各工序的施工方法以及每一种施工方法的质量控制措施展开了论述。研究成果不仅可以详细指导萧山机场飞行区地基处理和土方工程二标段工程施工,还可以为类似工程施工提供借鉴和参考。
[Abstract]:In recent years, in order to make the air transport network is more perfect, the state vigorously carry out the infrastructure construction of the airport. The urgent need to standardize the project management methods and means in the airport construction project management, construction organization design develop. Therefore, one needs to carry out how to ensure the construction quality, speed up the construction progress, save research the project construction cost, on the other hand to the theory and method of optimization design of construction organization, mining theory in engineering practice, further guide the practice in the theoretical basis, gradually formed on the construction organization design theory and construction schemes of different backgrounds and conditions. But at the present stage of the construction organization design for airport engineering project the research is less, the lack of supporting research results can directly guide the construction organization design scheme optimization theory and related technologies. Based on the two section of ground treatment and earth rock engineering of the two expansion project of Xiaoshan airport, the paper studies the construction organization design and optimization method for the ground treatment engineering of the airport area. The following conclusions are drawn:
(1) to analyze the important role of the construction organization design play in engineering construction and the construction project cost, schedule, quality. To explore the construction organization design theory and optimization method, put forward the construction organization of three elements of "cost, quality, schedule control method". Firstly, through the theory of value engineering method is studied. The control and optimization of the construction cost in the construction organization design, put forward the concept of value index and value index to evaluate the method through the construction scheme; secondly, the control and optimization of construction network planning technique used in the fuzzy AHP analysis method is used to optimize the construction scheme, construction period control selection the method and the reasonable construction scheme; finally, based on the cost, time and quality control method is put forward the theory and method of comprehensive optimization of construction scheme of multi targets, making application The organization design plan can make the time cost quality balanced and optimized. The research results will provide a theoretical basis for the optimization of construction organization design in actual engineering.
(2) to the foundation engineering flight zone two Hangzhou Xiaoshan International Airport expansion project construction for the actual engineering background, combined with the theory and method of construction organization design, optimization of construction organization design of foundation engineering in flight were studied. Put forward the overall plan of construction, construction site layout, construction progress control and quality control in the construction of a series of measures analyzes the factors and principles that should be considered in construction site layout, make the construction layout scheme suitable for airfield ground treatment and earthwork project bid two; use the construction schedule control method of construction schedule of airfield ground treatment and earthwork project two tenders for rational planning, put forward the construction progress schedule road map; combined with the construction of special practical site, put forward the control measures to ensure construction quality.
(3) for ground treatment and earthwork, the proposed implementation plan from the construction method and construction technology level. The construction technology of the earthwork ditch pond treatment construction technology, dynamicconsolidation construction technology, and construction technology of roller compacted fill is studied, proposed using fuzzy analytic hierarchy process than operation the process of construction scheme. The construction process of the project, the construction method of each process and the quality of each kind of construction method and control measures were discussed. The research results can not only guide the detailed flight area of Xiaoshan airport foundation and earthwork two section of engineering construction, can also provide reference for the similar engineering construction.
