Research on Construction of Sponge Airport in China

Abstract

This article is an introduction to the practices of sponge projects for airports in China. The objective of this paper is to point out the main problems existing in the construction of sponge airports and seek ways to improve the storage volume of airports. Data investigation, technical analysis, and engineering cases are used to conduct the research. The result shows that the main problem in the construction of sponge airport is the lack of effective sponge measures in the airfield area. Addressing the challenges and implementing effective sponge measures in airfield area is feasible and crucial for advancing sponge city concepts in airport construction. The elevation of pavement, particularly in creating sponge storage in unpaved areas, and using a drainage layer for the pavement and the shoulder stands out as a successful approach and should be considered in the design of airfield area projects.
