黄河峡谷区连续刚构桥冬季施工技术探析

Analysis on Winter Construction Technology of Continuous Rigid Frame Bridge in the Yellow River Valley

黄河峡谷区由于存在特有的“峡谷效应”,造成在黄河峡谷区的风相较于在平原区的风瞬间风力大、温度损失快。针对在该区域冬季施工条件及环境恶劣、工程质量问题多发的难点,依据《公路桥涵施工技术规范》制定了连续刚构桥上部构造在黄河峡谷区冬季施工期间的技术措施。通过对黄河峡谷区连续刚构桥冬季施工技术的分析总结,得出了黄河峡谷区连续刚构桥冬季施工技术一些共性特点。

Due to the unique"valley effect"in the Yellow River valley area,the wind in the Yellow River valley area is larger than that in the plain,and the temperature loss is faster;Winter is also a season with bad construction conditions and environment and frequent occurrence of project quality.During the winter construction of the superstructure of continuous rigid frame bridge in the Yellow River valley,corresponding winter construction measures must be formulated.This paper summarizes the winter construction technology of continuous rigid frame bridges in the Yellow River valley,and draws some common characteristics of the winter construction technology of continuous rigid frame bridges in the Yellow River valley,which can be used as a reference for the same type of projects to formulate technical measures for winter construction.
