摘要
为了控制某承台大体积混凝土浇筑质量,考虑钢筋作用,利用Midas/FEA对承台施工进行有限元分析。结果表明:考虑钢筋的影响,承台养护期温度更加均匀,温度应力也较小。因此在分析承台大体积混凝土水化热问题时,考虑钢筋的有利影响是有必要的。
In order to control the mass concrete pouring quality of a bearing platform,the finite element analysis of Midas/FEA was carried out for the construction of the bearing platform considering the effect of steel reinforcement.The results show that the temperature is more uniform and the temperature stress is smaller when the influence of steel reinforcement is taken into account.Therefore,it is necessary to consider the beneficial effect of steel reinforcement when analyzing the hydration heat problem of mass concrete bearing platform.
