【摘要】：随着经济迅猛发展的大趋势,交通运输压力陡增,航空运输业迅速崛起,航空运输的快速发展和大型飞机的广泛使用给机场工程带来了巨大挑战。毕节位于贵州西北部,地处云贵高原,平均海拔1400多米,由于地形复杂、气候恶劣、经济发展水平落后等一系列原因使得该地区交通基础设置严重滞后,对外人员、物资交流主要依靠公路运输,且技术等级较低,为彻底改变毕节地区交通运输严重落后的局面,加强物资人员交流,毕节飞雄机场建设提上日程。毕节飞雄机场位于市中心区东偏南方向的大方县飞雄村,距市中心直线距离约18km,跑道中心点坐标为北纬27°16′0.9″、东经105°28′16.5″,机场道面采用水泥混凝土。混凝土道面施工受气候湿润、雨量充沛,海拔较高、昼夜温差较大等自然条件影响,加之工期短、工程量大、质量要求高,使得施工过程中困难重重。机场地基及混凝土道面施工过程中如何削弱自然条件影响,按期高质量的完成毕节机场建设任务,成为该项目实施过程中的关键问题,也是该工程建设管理的核心内容。本文从项目管理角度着手,重点研究了机场工程施工组织、质量控制、进度安排、措施保障等方面的内容,对高原地区混凝土道面及高填方地基施工、评价具有重要的指导意义。本文主要针对以下内容展开研究:1、介绍了毕节机场项目施工组织的内涵及组成,总结了目前国内外机场道面、高填方地基先进的施工方法及后评价体系。2、结合毕节飞雄机场工程概况,提出了项目实施的主要内容、技术要求,分析了高原机场道面及地基施工的重点及不利条件。3、毕节机场地基施工包括了填方工程、爆破开挖工程、边坡防护等内容,从总体上制定了人员机械材料投入计划,优化了施工平面布置,重点分析了强夯法施工的适用范围和技术指标,制定了一系列质量控制及保障措施。4、从道面施工及组织角度,制定了道面施工的总体规划和施工平面布置,深入研究了道面基层施工、道面混凝土施工、接缝工程施工、灌缝施工、跑道道面刻槽工程施工、道面标志线施工方案和技术指标。5、分别从高填方地基安全、变形及道面整体状况等方面对项目施工进行了系统评价。本文对高原地区机场施工及组织及后评价具有一定的理论意义和实用价值,同时对恶劣条件下大方量水泥混凝土施工及控制具有显著的指导意义。
[Abstract]:With the rapid development of the economy, the rapid rise of the transportation pressure, the rapid rise of the air transportation industry, the rapid development of air transport and the wide use of the large-scale aircraft have brought great challenges to the airport engineering. Bijie is located in the northwest of Guizhou. It is located in the Yunnan-Guizhou Plateau, with an average altitude of more than 1400 meters. Because of the complex terrain, the bad weather and the low level of economic development, the traffic infrastructure in the area is seriously delayed, and the exchange of materials and materials mainly depends on road transport. And the technical level is low, so that the situation that the transportation in the Bijie area is seriously and backward is thoroughly changed, the communication of materials and materials is enhanced, and the construction of the Bijie Feixiong airport is carried out. Bijie Feixiong Airport is located at the Feixiongcun Village, Dfang County, in the south of the central area of the city, with a straight distance of about 18km from the center of the city center, and the coordinates of the center point of the runway are 27 掳 16 to 0.9 掳 N,105 掳 28 to 16.5%, and the airport pavement is made of cement concrete. The construction of concrete pavement is affected by natural conditions such as wet climate, abundant rainfall, high elevation, big day and night temperature difference and other natural conditions. In addition, the construction period is short, the engineering quantity is large, and the quality requirement is high, so that the construction process is difficult. How to weaken the influence of the natural conditions during the construction of the airport foundation and the concrete pavement is the key problem in the implementation of the project and the core content of the project management. This paper, from the point of view of project management, focuses on the content of airport engineering construction organization, quality control, schedule arrangement, measures guarantee and so on. It is of great significance to the construction and evaluation of concrete pavement and high-filling foundation in high-altitude area. This paper is mainly focused on the following:1. The connotation and composition of the construction organization of Bijie Airport Project is introduced, and the advanced construction method and post-evaluation system of the airport pavement and high-fill foundation at home and abroad are summarized. The main contents and technical requirements of the project implementation are put forward, and the key and adverse conditions of the high-altitude airport pavement and foundation construction are analyzed. In general, the investment plan of personnel mechanical materials is established, the construction layout of the construction is optimized, the application scope and the technical index of the construction of the dynamic compaction method are emphatically analyzed, a series of quality control and guarantee measures are developed, and 4, the construction and the organization angle of the pavement are obtained from the pavement construction and the organization angle, The overall planning and construction plan of the pavement construction are set up, and the construction of the pavement base course, the construction of the pavement concrete, the construction of the joint, the construction of the joint and the track, the construction of the pavement marking line, the construction plan and the technical index of the pavement marker line are studied in detail. The project construction is systematically evaluated in terms of the deformation and the overall condition of the pavement. This paper has a certain theoretical and practical value for the construction and post-evaluation of the airport in the high-altitude area, and has significant guiding significance to the construction and control of the large-volume cement concrete under the severe conditions.
