【摘要】：随着我国经济社会的发展,铁路系统不断地完善,铁路的建设也得到了跨越式的发展,目前我国的铁路建设主要是高速铁路的建设,铁路工程建设与我们的生活息息相关,它的建设保证了我们安全利于交通便捷。如今铁路建设迅速发展的同时也陆续的出现了很多的质量问题,很多的铁路建设单位为了自己的利益,不断地缩短工期,使得工程的进度加快,这样就会使得工程的质量严重下降,最后会导致工程的验收不合格,一些不安全的伤亡事件时常发生,这样也会引起铁路后续的质量问题层出不穷。只有加强工程施工质量的科学管理与风险防范,才可以达到建设的根本目的,完成建设的意义,以获得更高的收益。本文以A桥换梁工程为例,重点阐述了工程项目中质量管控以及风险评估的方法,并结合了铁路建设项目中的一些影响质量的风险因素进行了全面的分析。在上述分析的基础上将质量控制分为业主、施工单位、监理单位和其他勘察设计质量控制。接着用层次分析将项目施工风险评价为八种；最后提出施工质量控制方案,如对图纸的把握以及对施工工序的统筹管理、完善和遵守施工规范、合理分工责任难落实等；而对于技术上的湿接加固施工以及封锁和慢行等问题,制定了详细的质量控制方案,确保工程的保质保量进行。
[Abstract]:With the development of our country's economy and society, the railway system has been continuously perfected, and the railway construction has also been developed by leaps and bounds. At present, the railway construction in our country is mainly the construction of high-speed railway, and the railway engineering construction is closely related to our daily life. With the rapid development of railway construction, a lot of quality problems have emerged one after another. For their own benefit, many railway construction units continue to shorten the duration of the construction period. This will speed up the progress of the project, so that the quality of the project will be seriously reduced, and eventually the acceptance of the project will not be qualified, and some unsafe casualties will often occur. Only by strengthening the scientific management of construction quality and risk prevention, can the fundamental purpose of construction be achieved and the significance of construction be completed. In order to obtain higher income, this paper takes A bridge beam replacement project as an example, and expounds the methods of quality control and risk assessment in the project. Combined with some risk factors that affect the quality of railway construction projects, the paper makes a comprehensive analysis. On the basis of the above analysis, quality control is divided into owners, construction units, Supervision units and other survey and design quality control. Then use AHP to evaluate the project construction risk into eight types. Finally, put forward the construction quality control scheme, such as the grasp of drawings and the overall management of construction process, It is difficult to carry out the reasonable division of responsibilities and perfect and abide by the construction code. However, for the technical problems of wet joint reinforcement, blockage and slow running, the detailed quality control scheme is formulated to ensure the quality and quantity of the project is carried out.
