本文分析了三峡工程船闸陡高边坡的特点，通过力学计算与经济分析，确定了经济合理的边坡结构坡角，并在此基础之上从技术与经济等方面研究了一种新型的结构型式—地下洞室与边坡相结合的方案。这是一种解决三峡工程船闸陡高边坡的新途径，以此为三峡工程的建设提供必要的资料与数据。 This paper analyzes the characteristics of the steep and high slope of the Three Gorges Project shiplock. Through the mechanical calculation and economic analysis, the slope angle of the slope is determined economically and rationally, on the basis of which, a new type of structure is studied from the aspects of technology and economy Type - a combination of underground caverns and slopes. This is a new way to solve the steep high slope of the Three Gorges Project Ship Lock, so as to provide the necessary data and data for the construction of the Three Gorges Project.
