大体积混凝土的温度控制方案优化分析

介绍了大体积混凝土承台施工温度控制方案优化分析的思路、分析中采用的主要计算方法，通过运用该方法对天兴洲长江大桥承台大体积混凝土进行了多参数方案分析，证实采用修改方案能较大幅度降低混凝土内外温差，所得结果对施工具有很好的参考作用。

On optimized analysis of temperature control scheme in large-scale concrete

The paper introduces the temperature controlling scheme for the large-scale concrete bearing platform construction, introduces the ide- as of the optimized analysis, and the adopted calculation methods in the analysis, undertakes the multi-parameter seheme analysis of the large- scale concrete in the bearing platform of Tianxingzhou Yangtse Bridge by using the method, and proves the adoption of the modified scheme can lower the temperature differences inside and outside of the concrete, so the obtained result has sound reference to tile construction.
