| 摘 要： | 青藏铁路风火山地段海拔均为4800m以上，属高原冰雪型气候区，在混凝土结构中采用低(负)温早强高性能混凝土的质量控制。混凝土的耐久性指标检测周期长，难以用指标控制，因此只有将低(负)温早强高性能混凝土施工过程类比隐蔽工程控制模式进行控制，才能确保混凝土的耐久性质量得到有效控制。

| Abstract: | The Fenghuo Mountain section of Qinghai-Tibet Railway Project is located in ice and snow plateau area with elevation above 4800 m, and quality control of low (minus)-temperature early-strength and high performance concrete is adopted in concrete structures. Indicator test of concrete durability needs a long period and is difficult to control. Therefore only by referring the construction process control of the low (minus)-temperature, early-strength and high performance concrete to the controlling model of concealed works, could it be ensured that the quality of concrete durability is effectively controlled. |
