Study on the Application of Expressway Construction Based on Sponge City Concept

Abstract

Currently, in the active trial stage, sponge city concept has been applied in many low-impact development facilities on expressways in China, but many applications are not widely used. From four angles of pavement, slope, interchange and service area of expressway, this paper explains the adverse effects brought by rainwater, and then gives, and it carries out scene analysis combined with actual engineering projects with some feasible application schemes. Finally, the concept of sponge city at present is summarized, and it is considered that the optimal planning and design can be made only after establishing a reliable mathematical model and carrying out quantitative analysis.
