摘　　要：通过对3个高炉基础试件在竖向荷载和温度作用下的受力性能试验,分析温度作用对基础的影响,研究各荷载工况下不同约束条件、不同配筋的高炉基础的受力特点。结果表明:温度作用对高炉基础顶部圆台基墩附近影响较大;竖向荷载作用下天然地基的高炉基础底部应力水平较低,而桩基的高炉基础底部应力水平较高;基础上表面与圆台基墩、高炉框架柱、泥砲基础等相交位置以及基础变截面处受力复杂,仅配置构造钢筋的做法有待改进。The 3 specimens of blast furnace foundations under the action of vertical load and temperature effect were tested. The influence of temperature on blast furnace foundation is discussed, and the characteristics of foundation stress based on different grounds are compared. The conclusions are ： 1 ） only the top of the foundation is affected by temperature effect; 2）under vertical loading, the stress in the bottom of blast furnace foundation supported by uniform ground is low and the stress in ttie bottom supported by piles is high; 3） there is obvious stress concentration at the interface between foudation and the upper sturcture, the way of setting the constructional reinforcement needs improvement.
