摘要
对于大体积混凝土筏板基础在温度场影响下的应力变化和分布规律,结合具体的实际案例,现场监测得到了混凝土的温度和应力应变变化规律,并与计算得到的数值结果进行了对比,说明了研究结果的可靠性.研究表明大体积混凝土在发生水化热反应的过程中,不同时刻的温度场和应力场变化较大,尽早地进行混凝土开裂防治,能有效解决温度应力引起的表面裂纹问题,保证施工质量和安全.
In view of the influence of temperature field on the performance of mass concrete,this research gives a review of the relevant research at home and abroad.Based on a practical case,the temperature,stress and strain of the concrete are obtained by field monitoring,and the results are compared with the numerical results,a witness to the reliability of the research results.The research shows that the temperature field and stress field of mass concrete vary greatly at different times in the process of hydration heat reaction.Early intervention and prevention of concrete cracking can effectively control the cracking problem of mass concrete and ensure the progress and quality of the project.
