京沪高铁蕴藻浜桥跨既有铁路施工安全风险管理研究
摘要
京沪高铁设计正线数目为双线,设计速度350km/h,是目前我国一次建设完成的开通运营里程最长,设计技术等级最高的高速铁路。全线共有正线桥梁254座,跨越既有铁路73处,而最为复杂、施工难度最大的地点是京沪高铁蕴藻浜桥段跨既有铁路桥群,在方圆不足2平方公里范围内6跨既有铁路。该桥段所处地质为第四系地层覆盖,系海相沉积形成,为黏土、粉质黏土夹粉细砂层,软土强度低,压缩性高。该桥上跨既有京沪铁路,施工条件极其困难,确保行车安全和施工安全就显得尤为重要,是京沪高铁施工安全与既有铁路行车安全管理的重中之重。
本文从京沪高铁蕴藻浜桥工程范围,地质、水文条件及工程特点入手,简述了铁道部与上海铁路局既有线施工安全管理的有关规定,阐明了铁路长大跨度特殊结构桥梁上跨既有铁路的施工难点和重点。同时,按照安全风险管理的理论,对该工程存在的安全风险源进行了梳理和识别,总结出了三类安全风险源,对识别出的安全风险源进行了评价,并且通过数据对安全风险等级进行了确定,从而为安全风险管理提供了基础条件。
本文还从安全保证措施,封锁线路要点施工管理,重点工程安全控制技术措施,应急保障体系等方面阐述了京沪高铁蕴藻浜桥跨既有线施工安全风险管理的具体做法,同时也从安全管理理论相关定义、研究方法、风险源管理等方面阐述了安全管理有关的理论研究及分析。
本文总结了京沪高铁蕴藻浜特大桥黄渡桥段上跨既有京沪铁路的施工安全风险管理方法,归纳了铁路长大、特殊结构桥梁跨越既有铁路的安全风险管理方法,以及如何确保既有铁路的行车安全和施工安全所采取的各项控制措施,并从安全风险管理理论方面分析了安全风险管理的重点。希望本文能使目前铁路建设长大、特殊结构桥梁跨既有铁路施工的安全风险管理有所帮助和启发,为既有线行车安全和施工安全管理有所帮助。
The Beijing-Shanghai high-speed railway line is the longest one with the highest technical standards once-constructed currently in China. It is a double tracking line with the design speed of350km/h. There constructs254bridges and73points across the existing railway line. Among these, the most complicated and difficult construction site is Yunzaobang Bridge across the railway bridges of the existing line within the area of less than2square kilometers for6times. This bridge is located in the area of geological Quaternary of marine sedimentary formation with clay, silt clay, fine sand layer soft soil, characterizing low strength and high compression. The bridge spans across the existing railway line making construction very difficult. Therefore ensuring safe operation and construction becomes very important. It is the essence for the Beijing-Shanghai high-speed railway line construction and the existing line operation.
From the viewpoints of Yunzaobang Bridge Engineering, geological, hydrological conditions and the engineering characteristics, this article introduces the construction safety management regulations by the Ministry of Railways and Shanghai Railway Administration. Also it states the construction difficulties and important items for the special structure of Railway Long Span Bridges cross the existing line in the areas of the safety assurance measures, the blockade line points construction management, key project safety control technical measures, emergency safeguard system and other aspects of construction safety management practice. Meanwhile, this article also reviews and identifies the risks sources based on risks management theory. It summarizes, identifies and makes comments for the three categories of risks sources according to the related data. Therefore, the essential materials for risks management are provided. This article analyzes the safety management theory, research methods, sources of risk management and definitions.
It summarizes Yunzaobang Bridge construction safety management method across the existing line within Huangdu Bridge, and concludes the safety management method of the long and special railway bridge structures across the existing railway line and includes ensuring the existing railway line operational and construction safety control measures to be taken with the focus of safety management keys. The author hopes that this paper can contribute the valuable methods and proposals for the present construction of railway lines, the special bridges across existing railway lines to secure the construction and operation safety.
