Researches On Karst Grouth Features And Stability Of Kunming Newly Built Airdrome

Along with the economic development, the airdrome construction is strengthened to resolve the transportation problems in southwest of china in recent years. Lots of project problems appear due to the vast area and the arduous task. The grouth of Karst has the most prominent influence on airdrome construction, especially in Yun Nan province. Therefore, it is of great significance to conclude the karst grouth features and evaluate its influence on the airdrome projects.On the basis of fieldwork and analyzing materials of Kunming newly built airdrome, the thesis chooses the third area of the airdrome experimental areas as the research target, and discusses the karst grouth features and its influence on the project.The thesis accounts for the environmental geology background of the research area in terms of physical geography, stratum lithology, and geological structure, and concludes the hydrologic condition of the research area by means of analyzing aquifer features and ground water dynamic state condition. Secondly, the thesis discusses the karst grouth features, the vertical and horizontal grouth rules on the basis of analyzing the karst grouth condition, mechanism and influence factors etc. The thesis evaluates the karst stability of the target area through comparison and calculation. Lastly, suggestions and protect measures are put forward according to the karst grouth influence on the airdrome project.
