摘　　要：简述了国内多家科研单位所进行的外掺MgO混凝土自生体积变形试验内容,并对试验结果进行整理分析,得出外掺MgO混凝土的自生体积变形规律;总结了影响外掺MgO混凝土自生体积变形的主要因素;详细介绍并评述了两种数值模拟外掺MgO混凝土自生体积变形方法的优劣;为进一步适应外掺MgO混凝土技术在大坝混凝土中的运用提出了需要研究的内容。It was briefly introduced that the experimental study was performed on autogenous volume deformation of concrete mixed with MgO conducted by many Chinese scientific research unit, and the results of test were analyzed to conclude the law of autogenous volume deformation of concrete mixed with MgO.It summarized the main factors that influence autogenous volume deformation of concrete mixed with MgO.it also introduced in detail and comments about the pros and cons of the two kinds of numerical simulation of autogenous volume deformation, and put forward the needed content of study in order to make concrete mixed with MgO technology further adapt to the application of dam concrete.
