摘　　要：结合乌鲁木齐绕城高速(西线)工程PPP项目头屯河连接线特大桥主桥双肢薄壁空心墩系梁的特点,重点介绍了墩系梁支架的设计思路及施工工艺流程。该墩系梁支架方案由穿心棒法与满堂脚手架现浇支架法相结合,有效地解决了双肢薄壁空心墩系梁施工平台的搭设问题,既保证了施工安全,又节约了工程措施费,加快了工程进度,所取得的经验可为后续类似高墩系梁的施工借鉴。Based on the characteristics of the double-limb thin-walled hollow pier tie beams of the main bridge of the Toutunhe District super-large bridge in the PPP project of the Urumqi Ring Expressway(Western Route),this paper mainly introduces the design ideas and construction process of the pier tie beam support.The pier tie beam support scheme is based on the combination of the piercing core bar method and the cast-in-place support of full-scaffold method,and the combination of the two kinds of support schemes effectively solves the problem of setting up the construction platform of double-limb thin-walled hollow pier tie beams,which ensures the construction safety,saves the project measure cost,speeds up the project progress,and provides reference for the following similar high pier tied beam construction.
