摘要
针对青藏高原腹地多年冻土区恶劣自然环境和多年冻土独特工程特性条件下桥梁施工对混凝土提出的技术要求 ,通过热工计算 ,推导混凝土施工过程中各阶段的温度控制指标、措施和一些规律 ,对青藏铁路多年冻土区桥梁混凝土施工及其它严寒地区混凝土施工具有指导意义。
Considering the bad natural condition of Qinghai-Tibet Plateau and the special engineering character of perennial frozen earth ,the author carried out some research on getting temperature index,laws during concrete construction through calorific calculating,which will guide the concrete construction in perennial frozen earth area of Qinghai-Tibet Plateau and other chilly area as well.
