【摘要】 结合秦山核电厂一期工程和巴基斯坦CHASNUPP核电厂的设计和建造,着重介绍了上海核工程研究设计院在核电厂结构力学领域的主要研究工作。对于安全壳部分的结构力学问题,考虑了基岩和软土地基两种不同的情况,对于后者仔细研究了土和结构的相互作用。对于设备和管道的结构力学问题,研究了三维应力和三维断裂。结构动力学问题研究了包括流致振动、地震和失水事故的结构响应分析。管道部分着重介绍了破前漏技术的应用。文内介绍了大量的数学模型,采用的计算机程序,分析计算和试验结果,是对压水堆核电厂中的结构力学问题较完整的论述。更多还原

【Abstract】 The main research works in structural mechanics in reactor technology are emphatically introduced. It is completed by structural mechanics engineers at Shanghai Nuclear Research and Design Institute associated with the design and construction problems for Qianshan NPP Unit 1 and Pakistani CHASNUPP. About structural mechanics problem for the containment, the rock and soft soil two different bases are considered. For the later the interaction between soil and structure is carefully studied. About the structural mechanics problem for the equipment and pipings, the three dimensional stress and fracture analyses are studied. For the structural dynamics problem, including flow induced vibration, the response analyses under earthquake and loss coolant accident loadings are studied. For pipings, the leak before break technique has been emphatically introduced. A lot of mathematical models, the used computer codes, analytical calculations and experimental results are also introduced. This is a comprehensive description about structural mechanics problem in pressurized water reactor nuclear power plant.更多还原
