ENGINEERING CHARACTERISTIC ANALYSIS OF ROCK AND SOIL ALONG 750KV TRANSMISSION LINE FROM EAST OF LANZHOU TO EAST OF YINCHUAN

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.
