摘要
重庆市曾家岩大桥为三跨连续刚性悬索加劲钢桁架梁桥,跨径布置为135m+270m+135m,为跨嘉陵江的重要市政桥梁。针对周边建筑物密集、大桥上方存在高压电缆等限制条件,论述了在桥位环境影响下施工方案的比选,简述了钢桁梁施工相关设计和施工工艺。在钢桁梁拼装及吊装过程中,制定了针对性的施工方案和相关安全质量控制措施,取得了较好的效果。
The Zengjiayan Bridge which has special rigid cable is a three-span continuous steel truss bridge of 135 m + 270 m+ 135 m and it is an important municipal bridge across the Jialing river.There are a large amount of construction around the bridge. There are high voltage cables above the bridge and the other limit. This paper gives several construction methods in view of the above-mentioned fact and selects the best one. This paper consists of design concept, construction method contrast and corresponding construction technique. In the process of assembling and hoisting steel truss beams, pertinent construction schemes and related safety and quality construction measures have been formulated, and good results have been achieved.
