随着特高输变电工程的开展，越来越多的特高压变电站将会相继建设，针对特高压变电站设备基础施工属于大体积混凝土施工这一特点，文章基于理论计算与有限差分数值模拟计算相结合的方法，从1000kV特高压皖南站为应用实例出发，为后期的施工提供保障，得出大体积混凝土3至7天左右内部温升较快，约9天左右时间温升最大值；应力云图显示基础中部表面位置拉应力较大，需要做好防裂措施；借此一些有益结论为后期相似施工提供参考。

With the development of the UHV transmission and transformation project , more and more UHV substations will be built .Aiming at the characteristic of UHV substation equipment foundation con-struction belonging to the large volume concrete construction , based on the method combined the theoreti-cal calculation with finite difference numerical simulation calculation , this paper takes the 1000kV UHV substation of Wannan as an example , provides the guarantee for the later construction .It shows that the temperature rise is faster inside the large volume concrete from 3 to 7 days, reaching the maximum at the ninth day , and the stress nephogram shows that the tensile stress is bigger in the central of the founda-tion, needing to do some measures to prevent the cracks .The conclusions can provide some references for the later similar constructions .
