基于科研资源的土木工程材料实验教学拓展探索

Exploration on expansion of experimental teaching for civil engineering materials based on scientific research resources

针对土木工程材料实验教学与工程脱节的问题,结合自身机场混凝土道面的科研资源,提炼出不同强度混凝土单轴压缩实验。引入混凝土破坏的能量计算方法,分析混凝土破坏的能量演化机制,并判断其突然劣化危险性等级。这种"科研—实验—拓展—辩证—工程"五位一体实验教学方案,使学生对土木工程材料知识产生更深层次的理解和认识,提高学生辩证分析工程问题的能力。

In view of the problem about the disconnection between the experimental teaching of civil engineering materials and the engineering,and in combination with its own research resources for the airport concrete pavement,the experiment on the concrete under the uniaxial compression with different strength is set up.The energy calculation method of concrete damage is introduced to analyze the energy evolution mechanism of concrete damage and judge the danger grade of its sudden deterioration.This kind of the five-in-one experimental teaching scheme with“Scientific research-experiment-expansion-dialectics-engineering”enables students to obtain a deeper understanding of the knowledge about civil engineering materials,and improve their dialectical analysis ability of engineering problems.
