【摘要】：公路桥梁是国家的重要基础设施,是保证各种物资顺利流通的咽喉。其一旦受破坏,修复较困难,需要花费大量的人力、物力、财力,并会造成长时间的交通不便。随着我国经济的快速发展,由于早期建设的桥梁标准低和承载力不足,进而阻碍交通畅通,成为公路交通“瓶颈”。特别是大型、重型车与日俱增,致使公路交通安全与畅通受到严重影响,为此加固、改造、拓宽改建提高现有桥梁的行能力和服务水平,以缓解日趋紧张的交通压力,从而使桥梁建设可持续发展问题日显重要和突出。桥梁改造工程项目日益增多,桥梁施工工程质量对路网的整体性有着重要的影响。在客观因素的影响下,桥梁的质量存在很大的问题,这些因素包括施工人员操作不当、施工方法不科学等等。这些现存问题不仅损坏了桥梁的质量、缩短了桥梁的使用寿命周期,更重要的是给行人和行车带来了极大的安全隐患。珠岩大桥经过检测机构评定为四类桥需要对其进行改造,工程于2013年8月16日发布招标公告,9月10日签订施工合同。2013年9月12日开工建设,计划2014年11月底通车。作为项目管理中的重要内容,桥梁安全,责任重于泰山,事关公路交通安全畅通,事关人民群众生命财产安全,事关行业形象和政府公信力。本文通过国道烟上线珠岩大桥改造工程项目为研究对象,通过全面质量管理方法,即各种体系的构建,使用4M1E法,研究分析质量管理中的各项影响因素及保障措施,而采用的全过程控制方法及控制措施,特别是运用了直方图方法控制桥梁改造中水泥混凝土强度,及三阶段控制方法取得了显著的效果,有助于今后控制桥梁质量。
[Abstract]:Road and bridge is the important infrastructure of the country, and it is the throat to ensure the smooth circulation of all kinds of materials. Once it is damaged, it is difficult to repair, and it needs to spend a lot of manpower, material and financial resources, and the traffic is inconvenient. With the rapid development of China's economy, the low standard of bridge and the lack of carrying capacity in the early construction, and then hindrance. Obstructing unblocked traffic has become the bottleneck of road traffic. Especially large and heavy vehicles are increasing, and the safety and smooth traffic of highway traffic are seriously affected. Therefore, strengthening, reforming, widening and improving the capacity and service level of existing bridges, in order to alleviate the increasingly tense traffic pressure, and thus make the bridge construction sustainable development problem day. The quality of the bridge construction engineering has an important influence on the integrity of the road network. Under the influence of the objective factors, there are a lot of problems in the quality of the bridge, such as the improper operation of the construction personnel, the unscientific construction method and so on. These existing problems not only damage the bridge, but also damage the bridge The quality of the bridge has shortened the life cycle of the bridge, and it is more important to bring a great danger to pedestrians and driving. The pearl rock bridge has been evaluated as four types of bridges to be reformed. The project was announced in August 16, 2013, and the construction of the construction contract in September 12th.2013 was signed in September 10th, and the 2014 1 was planned. As an important part of the project management in the end of January, the bridge safety and responsibility are more important than the mountain, it is related to the safety of the road traffic, the safety of the people's life and property, the image of the industry and the government's credibility. In the construction of the system, the 4M1E method is used to study the influence factors and safeguard measures in the quality management, and the whole process control method and control measures adopted, especially the histogram method is used to control the strength of cement concrete in the bridge transformation, and the three stage control method has achieved remarkable effect, which helps to control the bridge in the future. Quality.
