摘要
结合斯里兰卡南部铁路工程,针对大体积混凝土水化热问题,阐述了国内关于其温度和温度应力的计算方法,并与现场实测数据进行了对比。介绍了英标中关于混凝土水化热防裂钢筋的计算方法,并就其合理性进行分析。研究成果可为今后类似工程提供有益参考。
In this paper, key issues associated with early thermal effects due to hydration process of massive concrete pour that have been carried out in Southern Railway Extension Project in Sri Lanka are elaborated and discussed, including thermal stress analysis in accordance with local practices and anti-cracking reinforcement calculation method with British Standards, and also those considerations were compared with data obtained from field survey. This study provides a useful reference for future projects with similar nature.
