Abstract:Kunming New Airport is the special major projects of Eleventh Five-year as the fourth largest airport in China.There is about 2 billion cubic meters foundation treatment earthwork.After the leveling of flight zone various surrounding slopes are formed and large slopes are formed especially in some locations of runway.Thus the seismic strengthening and treatment are particularly important.Based on the actual conditions posite seismic strengthening design and treatment of soil cave and karst cavity in every subarea are introduced.Then test method is suggested.The treated foundation can meet the requirements of project.
