This paper deals with the temperature and displacement fields of the top mid-block of south transition at Long Spruce Generating Station, in the North of Manitoba, Canada. According to the experimental results of Manitoba Hydro in the past two years, the top mid-block is assumed to be a rectangular one that has two supposed temperature distributions at its boundary sides. Then, the temperature fields for the top mid-block are obtained from the analytical solutions by separation of variables. By using the analytical solution of temperature field, the displacement behavior of the top block in various temperature fields is discussed in details. The numerical results are given to show the causes of the leakage between the top mid-block and the dam. Finally, the repair methods for leakage are discussed for practical leaking repair and its engineering applications.  相似文献

从1996年到今天,整整十年时间,上海大学土木工程系从办大土木的视角出发,立足上海、服务全国,主动适应国家经济社会日益发展对土木工程人才的需求。在土木工程系的本科教育中,我们率先在国内探索并开展了“土木工程概论”课程的创立与建设工作。在课程建设初期,我们就在定位上瞄准了争创国内一流的目标;在内涵上实现教学规律和工程规律的结合;在模式上立足于立体化的全程建设;在理念上把握把教的创造性留给老师,把学的主动权还给学生。十年来,我们围绕课程建设,在师资队伍、课程、资源、教学改革、科学研究以及教学形式、方法、手段、情景设…  相似文献
