苏通大桥辅桥主墩承台大体积混凝土施工温度控制

Temperature Control of Construction of Massive Concrete for Main Pier Pile Caps of Secondary Navigable Spans of Sutong Bridge

提出大体积混凝土结构施工温控的思路和工作流程。介绍苏通大桥辅桥主墩承台大体积混凝土施工温控的施工方案决策计算结果及施工过程控制计算,并与温度监测结果进行了对比分析。对类似工程具有一定的指导意义。

This paper puts forward the considerations and work flow for temperature control of construction of massive concrete structures, presents in considerable details the calculation results for finalizing the construction scheme of temperature control and calculations for the construction process control of the massive concrete for main pier pile caps of the secondary navigable spans of Sutong Bridge, and analytically compares the results of the calculations to those of the temperature monitoring. The presentations in the paper are of certain guidance to the construction of similar concrete works.
