特殊环境对现浇混凝土的影响及相应的质量控制措施

摘要

According to the problems existing in the construction,starting from 18# cracks of the Hami-Lop Nor Railway S2 section Changbai Mountain super majors bridge,this paper explores the impact of special natural environment on the quality of concrete structures.It is pointed out that how to improve the quality control measures of cast-in-place concrete under the special natural environment,such as high temperature,drought,high frequency of wind and large temperature difference.%本文根据施工中存在的问题,从哈罗铁路S2标长白山特大桥18#墩身裂缝入手,探讨特殊自然环境对结构物混凝土质量的影响,指出如何在高温,干旱,大风频率高,温差大等特殊自然环境下提高现浇混凝土的质量及控制措施.
