Abstract: In order to afford the accurate engineering data of rock and soil along the new 750 kV Transmission Lines from east of Lanzhou to east of Yinchuan,an all-sided geotechnical engineering Exploration is needed. The landform,phsiognomy,geologic construct,earthquake and area characteristic of geotechnic is presented along an 193.246 km-long transmission Line in Ningxia area .and the original data of engineering geological properties,liquefaction of soil,causticity of soil, Collapsible Loess and its class is gived . Also some idiographic advise for loess,desert and erode development area foundation disposing in this area.is put forword.
