Teaching Design Model of Bridge Aesthetics Course Facing Ecological Landscape Sustainable Development

In recent years, ecological building of bridges has gradually begun to appear in cities, and this trend is conducive to the sustainable development of urban bridges and an ecological environment, promoting the development of emerging industries around cities and driving the development of the urban economy. Bridges’ ecological aesthetic design cannot be separated from ecological aesthetics, and the relationship between these two factors is complementary and inseparable. This paper focuses on the relationship between the teaching of a bridge aesthetic design course and ecological landscape sustainable development. Based on a visual impression hierarchy deep learning model and a statistical analysis of a questionnaire, including reliability and validity analyses, a teaching model for the design of landscape bridge structure systems was constructed. Landscape bridge structure systems combine the dimensions of function, form, mechanics, and culture, and the teaching design model of landscape bridges must include non-professional students, undergraduate students, graduate students, and graduates working in enterprises. Investigations were performed of the urban block landscape, water environment landscape, urban garden landscape, and landscape bridges within natural mountain landscapes. The results showed that: (1) the influence and role of landscape aesthetics related to the water environment and urban garden landscapes are the most important; (2) in the teaching of a bridge aesthetics course, sustainable ecological development must consider the aesthetic value of landscape bridges while ensuring function and safety; and (3) for students at different learning stages, the focus in terms of bridge aesthetic system elements is different. Both the bridge structural landscape configuration and the ecological aesthetics must be considered together during the teaching of bridge aesthetics design courses. To achieve such a goal, students at different levels must have a good understanding of ecologically sustainable development and bridge aesthetics.
