【摘要】：近些年来，随着我国公路交通事业的快速发展，桥梁的跨越能力越来越强，各类大跨径桥梁在我国修建，其中预应力混凝土连续刚构桥在设计中的频繁采用尤为突出。与同类桥（如连续梁桥、T形刚构桥）相比：多跨刚构桥保持了上部构造连续梁的属性，具有跨越能力大、施工难度小、行车舒顺、养护简便、造价较低等优点。因此在我国新建桥梁中占的比重急剧增大。论文研究和总结了国内外连续刚构桥的发展现状及趋势，并结合工程实例（以三水河特大连续刚构桥为例）对施工生产过程中的安全管理和技术进行了研究，对施工过程中各种生产施工工艺的重点、难点进行分析和论证，，对大跨度连续刚构桥的施工安全技术进行科学理论的论证。通过对连续刚构桥施工安全技术分析，使得此类桥梁的施工安全技术更加可靠、并能减少损失，使得施工更加优化。研究成果具有实用价值。研究将具体分为如下四部分阐述:第一部分现阶段连续刚构桥施工安全问题的由来。第二部分通过对连续刚构桥的国内外发展情况、结构特点，分析连续刚构桥施工特点。第三部分将从施工组织，机械使用等特点对连续刚构桥施工安全管理问题提出技术措施。第四部分将通过工程实例（三水河特大桥)的施工工艺和注意事项来解决连续刚构桥施工安全问题，与此同时将进行施工安全技术的理论论述。
[Abstract]:In recent years, with the rapid development of highway transportation in our country, the span ability of bridges is more and more strong, all kinds of long-span bridges are built in our country. Compared with similar bridges (such as T-shaped rigid frame bridges), multi-span rigid frame bridges maintain the properties of superstructure continuous beams, and have a large span ability, especially in the design of prestressed concrete continuous rigid frame bridges. The construction difficulty is small, the traffic is smooth, the maintenance is simple and the cost is low, so the proportion of new bridges in our country increases rapidly. This paper studies and summarizes the development status and trend of continuous rigid frame bridge at home and abroad, and studies the safety management and technology in the process of construction and production in combination with engineering examples (taking Sanshuihe super continuous rigid frame bridge as an example). This paper analyzes and demonstrates the key points and difficulties of various production and construction techniques during construction, and proves the construction safety technology of long-span continuous rigid frame bridge in a scientific and theoretical way, through the analysis of construction safety technology of continuous rigid frame bridge. It makes the construction safety technology of this kind of bridge more reliable, and can reduce the loss and make the construction more optimized. The research results have practical value. The research will be divided into the following four parts: the first part of the continuous rigid frame bridge construction safety problems, the second part of the continuous rigid frame bridge development at home and abroad, structural characteristics, Analysis of the construction characteristics of continuous rigid frame bridges. The third part will be organized from the construction, This paper puts forward technical measures for the construction safety management of continuous rigid frame bridge. 4th part will solve the construction safety problem of continuous rigid frame bridge by engineering example (Sanshuihe super bridge) construction technology and matters needing attention. At the same time, the construction safety technology will be discussed theoretically.
