新疆地区简支梁桥变连续梁桥施工技术

Construction Technology of Simply Supported Beam Bridge into Continuous Beam Bridge in Xinjiang area

新疆地区海拔高、气温低、环境条件恶劣,在该地区进行桥梁施工时,施工难度较大。简支梁桥变连续梁桥的结构形式具有很多优点,在新疆地区大量采用。鉴于此,在介绍简支梁桥变连续梁桥原理的基础上,从架设预制主梁、浇筑接缝处的混凝土、负弯矩区钢筋的张拉等方面介绍了简支梁桥变连续梁桥的施工方法,并阐述了施工中应采取的措施,可为相关施工提供参考。

Xinjiang area is of high altitude, low temperature, harsh environmental conditions, which increases the difficulty of construction in the district. The structure of simply supported beam bridge to continuous girder bridge has many advantages, which is widely used in Xinjiang. In view of this, based on introducing the principle of simply supported beam bridge into continuous beam bridge, from the aspects such as erection of precast main girder, pouring concrete in joints, the stretching-drawing of concrete iron in hogging moment area, and so on, the paper introduces the construction technology of simply supported beam bridge into continuous beam bridge, and expounds the measures adopted in construction, which can provide reference for relevant construction.
