| 中文摘要: |
| 通过对氧化镁混凝土在变温条件下膨胀特性的分析，指出了传统计算方法的不足，提出了计算变温过程中膨胀变化的当量龄期法，即采用变温后曲线相同膨胀量处的切线斜率计算膨胀量。并以温度突升突降过程、温度突变的典型过程及典型的温度过程的3个算例与试验结果进行验证，证明该计算方法可行。 |
| 英文摘要: |
| A method for calculating the expansion of MgO concrete in the process of varied temperature,namely equivalent age method,is proposed.In this method the expansion is calculated according to the tangent slope of the curve at the point with the same expansion after varied temperature.The calculation results of 3 typical examples characterizing the situations of rising or dropping of temperature show that the proposed method is feasible. |
