我国在悬索桥、拱桥、连续刚构桥等方面的研究与实践取得了较好的成果,但对大跨预应力混凝土连续梁桥的施工控制技术研究相对较少。因此研究和应用大跨预应力混凝上连续梁桥施工控制技术具有极现实的工程意义。本文首先分析了大跨桥梁影响施工控制的因素,其次对施工控制的内容及方法、施工控制的基本原理等进行了的阐述。
China has achieved good results in the research and practice of suspension bridges, arch bridges and continuous rigid frame bridges. However, there are relatively few studies on the construction control technology of long-span prestressed concrete continuous beam bridges. Therefore, research and application of large span prestressed concrete continuous girder bridge construction control technology has a very practical engineering significance. This paper first analyzes the factors that affect the construction control of long-span bridges, and then elaborates the contents and methods of construction control and the basic principles of construction control.
