本文主要是介绍从T梁架设开始的先简支后连续的施工桥梁支座结构施工技术过程、技巧做了一些探讨,该方法的突出优点在于能够保证质量,同时能克服普通钢筋混凝土连续梁墩顶负弯矩容易开裂的问题,方法简单可行。对中小跨径预应力混凝土桥,先简支后连续无缝桥梁是一种经济合理的具有较强竞争力的桥型。先简支后连续桥梁具有行车平稳及整体性好等优点。
This article mainly introduces the construction technology process and skill of bridge abutment structure after simply supported and continuous construction starting from T girder. The outstanding advantage of this method is that it can guarantee the quality, meanwhile it can overcome the common reinforced concrete continuous beam pier Top negative moment easy to crack problem, the method is simple and feasible. For small and medium-span prestressed concrete bridge, the first simply supported seamless continuous bridge is a kind of economic and reasonable bridge with strong competitiveness. After the first simple support after a continuous bridge with smooth and good overall advantages.
