结合工程实例对大跨度高速铁路连续梁施工技术再分析结合工程实例对大跨度高速铁路连续梁施工技术再分析 摘要：随着我国交通事业的迅速进展，我国相继修建了许多大跨度预应力混凝土桥梁。预应力混凝土连续梁由于受力合理、行车平顺、施工方便、养护费用少等优点在工程上被大量采纳。随着我国高速铁路的日益增多，大跨度连续梁这一施工技术必定会获得更加广泛的应用。为了确保工程的总体质量，一方面应当不断加强设计工作，这是确保施工质量的根本，另一方面应当在施工过程中对各个环节的施工要点加以了解和掌握，这样有利于提高施工质量。只有这样才能进一步确保工程整体质量，进而保证铁路行车安全。下面以某高速铁路工程为例，对大跨度连续连施工技术进行浅谈。 关键词：高速铁路；大跨度连续梁；施工技术 Abstract: With the rapid development of transportation in our country, our country has built a lot of long span prestressed concrete bridge. Prestressed concrete continuous beam has the advantages of reasonable force, driving comfort, convenient construction, low cost of maintenance and is widely used in the engineering. With the increasing of our country's high-speed railway, large span continuous beam which is a construction technology will have more extensive application. In order to ensure the overall quality of the project, on the one hand should continue to strengthen the design work, it is essential to ensure the construction quality, on the other hand, should understand and grasp the key points of construction of each link in the process of construction, so as to improve the quality of the construction. It is the only way to further ensure the quality of the whole project, and guarantee the safety of railway traffic. Following takes a high-speed railway project as an example, the construction technology of long span continuous even on. Key words: high speed railway; large span continuous beam; construction technology 中图分类号：U445...
