The structure of airport runway has changed the balance of water movement between the original surface and the atmosphere, resulting in the accumulation of water under the base of airport runway surface, forming a “pot-cover effect”, aggravating the uneven settlement of the foundation under aircraft load, resulting in the destruction of the structure of the runway surface, frequent diseases, and seriously affecting the airworthiness of the runway. In order to solve the problem of water enrichment under the base of the runway surface, this paper proposes a specific layout scheme of diversion canals. In the runway overhaul project of Shenyang Taoxian International Airport, the water diversion canal was excavated on the spot, and it was found that the water level at the site was comparatively consistent with the water level at the scheme analysis. The layout scheme of the water diversion canal was reasonable and effective, and could well solve the problem of “pot-cover effect”.
