| 摘 要： | 本文采用跟踪养护的方法对多年冻土环境下的混凝土强度发展进行了试验模拟．并与标准养护及恒负温养护混凝土强厦发展进行了对比。结果表明：粉煤灰掺量在较低温度范围(0℃～10℃)内等量取代水泥时对混凝土的强度降低很敏感。确定了多年冻土环境下混凝土强厦发展规律的试验方法。

| Abstract: | The development of compressive strength of concrete in permafrost region environment was experimentally simulated.The tracking curing method was adopted,and the results indicate that the dosage of fly ash has a sensitive effect on compressive strength of concrete when fly ash equivalent replaces cement within lower temperature range of 0 to 10.The tracking curing method of determination development law of compressive strength of concrete was proposed. |

| Keywords: | tracking curing permafrost equivalent replacement development of compressive strength |
