Foundation treatment volume of excavation and filling is more than 200 million m , and the elevation after leveling of the airport flight zone is about 2096m, which forms different degrees of slope in surrounding region, particularly in the middle and south ends of west runway and the north and south ends of east runway. Through comprehensive methods for flight road tank area and slop stability influence area, strengthening design treatment construction is chosen for relatively weak foundation.
