中文摘要：

混凝土硬化过程中水泥的水化热温升是引起混凝土核废料贮存容器早期体积变形的主要因素。研究水化热产生的温度场变化以及由此引起的温差应力对研究和控制核废料贮存容器早期裂缝的出现，提高其耐久寿命具有重要意义。采用试验和模拟相结合的办法，通过在浇筑混杂纤维混凝土容器试件时预埋测温元件测定温度变化，并利用ANSYS进行了水化热温度场和温度应力的数值模拟。结果表明：二者所得的温度数值吻合较好，并得到温度应力最大值出现在混杂纤维混凝土核废料容器内壁与底面的结合处。

英文摘要：

In hardening process of concrete, temperature of cement heat of hydration is the main factor to cause an earlier volume defor- mation of nuclear waste container.it is of great significance for studying and controlling early appearance of cracks of nuclear waste con- tainers and improving durability of its life to study the changes of temperature field and thermal stress caused by heat of hydration.A ap- proach of the combination of experimental and simulation was used in the article, temperature measurement was proceed by temperature measurement device embedded while pouring nuclear waste fibers containers, and make numerical simulation by using ANSYS.Seen from the results, the temperature values showed good agreement, and reached the location of maximum temperature stress appeared the junction of fibers reinforced concrete nuclear waste container wall and bottom.
