四孔一联大跨连续梁施工方案分析与管理探讨

摘要

以杭黄铁路跨浙江 S103省道四孔一联（60+100+100+60）m 大跨连续梁工程为例，根据现场施工条件，通过对连续梁施工三种方案的对比分析，确定了最佳方案，并提出了方案的管理措施，有效地控制了节点工期，节约了施工成本。%Taking four-hole one-league(60 + 100 + 100 + 60)m large-span continuous beam engineering of Hang-Huang railway crossing Zhejiang provincial highway S103 as an example,according to the site construction conditions,through comparatively analyzing here continuous beam con-struction schemes,the paper determines optimal scheme,and puts forward the scheme management measures. As a result,it effectively control joint construction duration and saves construction cost.
