青藏铁路站房小体积混凝土高寒条件下施工技术

Construction Technology of Concrete with Little Volume used in Station Structures of Qinghai-Tibet Railway under Ultro-cold Condition

介绍青藏铁路首批试验站房工程玉珠峰车站小体积混凝土在高原高寒条件下施工的关键控制环节,对施工过程中混凝土的温度变化、成熟度及强度增长进行了计算,并详细介绍了高寒条件下混凝土施工的技术保障措施.

This paper introduced the key-technology of concrete constuction used in YuZhufeng Station, which is the first experimental station structure with little volume of Qinghai-Tibet Railway under the condition of high plateu and ultro-cold weather. The temperature of concrete, volution stage and devolpment of strength during construction are calculated, and the measure for technology guarantee is also given in detail.
