毕业环节中提高学生工程实践能力的探索与实践

本文以过程装备与控制工程专业为例,探讨了毕业环节中如何提高学生的工程实践能力。内容涉及此环节教改实施的全过程。具体做法包括把工程实际中的研发与设计等课题引入本科生毕业设计环节中来,把专业综合课程设计和毕业设计贯穿组合,在毕业环节中植入有工程实际意义的专题设计等项工作。文中有工作体会,有理论论述,有效果分析。文中提到的观点和做法,期待与同行共同探讨。

Preface for special section on long-term behavior of dams

When it comes to the long-term operation of hydropowerplants, the service life of mechanical and electrical equipmentand the reliability of hydraulic engineering structures areboth crucial. The loading history and interaction of theconstruction with ground settlements, earthquake activities andflooding, chemical reactions with water, overtopping, and thestate of weathering and aging of the construction material mayplay an important role in the safe operation of hydraulicstructures such as earth, rockfill, and concrete dams, as wellas novel reinforced soil structures. A critical reduction ofthe safety of dams can be caused by the evolution of internalerosion, cracks in the sealing, earthquake-induced deformations,reduction of the slope stability of earth and rockfilldams triggered by heavy rainwater infiltration, or rapid reductionof the water level in the reservoir.
