【摘要】：当今世界,国内外铁路既有线改造工程都具有施工量较大,工程数量大,工期紧,点多线长等特点。另外,路基、桥涵、站场及轨道改造施工过程中对既有线运营会产生一定的影响,施工干扰大,施工与行车的矛盾较为突出,保证施工质量及运营安全始终是既有线提速改造的一大难点,成为值得研究的一项课题。本文通过对国内外铁路施工过程中对轨道工程、路基工程、桥隧工程等各个方面的风险管理进行了详细的分析,并以武嘉线提速改造施工质量风险管理为研究对象,分析了工期、安全、质量、成本、环保等问题,并针对出现的问题分析其原因,并制定相应的对策,不断提高工程质量,确保我国铁路既有线提速改造工程有效实施。通过研究国内外铁路施工工程建设中质量风险管理的发展和现状,指出了传统工程质量风险管理中存在的问题,并采用系统动力学的方法,分析了提速改造施工中存在的质量管理风险因素,绘制出施工过程中的因果反馈回路,从而来控制工程项目质量,目的在于形成有效的风险管理方式,对既有线提速改造工程提供参考价值。通过本文章的研究,运用新理念新方法来建立和完善了既有线提速改造工程的风险管理体系,从系统的角度分析了铁路既有线提速改造施工过程中面临的一系列问题,并且从整体的视角看待工程建设项目质量风险发挥了积极作用。从整体的角度来看待与控制协调施工质量,加强安全施工风险的识别,准确的把握安全风险管理,对于管理者来说具有一定的研究价值。从源头把控施工安全风险,提出有效的风险管理方法,将风险影响程度降至最小。另外,使用系统动力学方法来分析处理是一种新的尝试,更是一种突破,并在实际施工现场收到了一定的成效。
[Abstract]:Nowadays, the reconstruction projects of existing railway lines at home and abroad have the characteristics of large construction volume, large number of projects, tight construction period, long points and multiple lines, and so on. In addition, the construction process of subgrade, bridge and culvert, station yard and track will have a certain impact on the operation of the existing railway line, the construction interference is great, and the contradiction between construction and driving is more prominent. Ensuring the construction quality and operation safety is always a major difficulty in the speed-up transformation of the existing railway line, and has become a topic worthy of study. Based on the detailed analysis of the risk management of track engineering, subgrade engineering, bridge and tunnel engineering and so on in the process of railway construction at home and abroad, and taking the construction quality risk management of speed-raising transformation of Wujia Line as the research object, this paper analyzes the problems such as time limit, safety, quality, cost, environmental protection and so on, analyzes the causes of the problems, and formulates the corresponding countermeasures to continuously improve the quality of the project. To ensure the effective implementation of the speed-raising and reconstruction project of the existing railway lines in our country. By studying the development and present situation of quality risk management in railway construction at home and abroad, this paper points out the problems existing in the traditional engineering quality risk management, analyzes on the risk factors of quality management in the construction of speed-raising transformation by using the method of system dynamics, and draws out the causality feedback loop in the construction process, so as to control the quality of the project, in order to form an effective way of risk management. To provide reference value for the speed-up transformation project of the existing railway line. Through the research of this paper, this paper establishes and perfects the risk management system of the speed-raising and reconstruction project of the existing railway line by using the new concept and new method, analyzes a series of problems in the construction process of the speed-raising transformation of the existing railway line from the systematic point of view, and plays a positive role in looking at the quality risk of the engineering construction project from the overall point of view. From the overall point of view, it is of certain research value for managers to look at and control the coordinated construction quality, strengthen the identification of safety construction risk, and accurately grasp the safety risk management. From the source, the construction safety risk is controlled, and the effective risk management method is put forward to minimize the risk influence. In addition, the use of system dynamics method to analyze and deal with is a new attempt, but also a breakthrough, and has achieved some results in the actual construction site.
