Abstract: The proposed siteis located in the Aksu area in southern Xinjiang,which is the Kuche River alluvial plain.The terrain is relatively flat.The construction projects include airport runways,terminal buildings,office buildings and ancillary buildings.In addition to conventional drilling during the survey,the geotechnical characteristics and the bad soil were tested and analyzed by pumping test,on-siteimmersion load test and SPT.Though Groundwater,sand liquefaction,corrosive and saline soil were analyzed.It was summarized the problems that should be paid attention to when conducting geotechnical investigations in desert arid areas.
