栗子坪1号大桥整体式大盖梁施工技术

Integrated Large Bent Cap of Liziping Bridge No.1

栗子坪1号大桥整体式大盖梁工程其大跨度预应力混凝土连接刚构梁曲线和高墩非常复杂,大盖梁的线性和内力与施工技术紧密相连。通过对工程情况、计划安排以及施工准备等进行有效分析,结合相关理论计算和相应的实践进行技术性的探讨与总结,并制定科学的施工方案,从而确保了大盖梁施工取得成功。

In the integrated large bent cap project of Liziping Bridge No.1, the curve of long- span pre- stressed concrete continuous rigid frame beam and its high pier are very complicated. The linearity and the inner force of large bent cap are closely linked with the construction technology. The article analyzes the engineering conditions, planning arrangement and construction preparation, discusses and sums up the relative theoretical calculation and the relative practical technology, and drafts the scientific constructionscheme so as to ensure the successful construction of large bent cap.
