The disaster of Heifangtai area is very serious due to Landslides and loess collapsibility caused by watering diversion irrigation, it has became One of the hotspots of Geological hazard research and engineering practice.The underground water level was lifted by the methods of flood irrigation was the root cause leading to the landslide in Heifangtai is developmental.To figure out the aquifer structure and water conditions of Heifangtai area is very critical for carrying out induced loess landslide control by irrigation.This time we carry out the surface nuclear magnetic resonance and IP sounding,Combined with the drilling data, we find out the aquifer structure and water containing situation of each aquifer in this area.There are three aquifers in Heifangtai area, aquifer of Superficial loess layer, aquifer of Hole and crack in loess and aquifer of sand gravel and bedrock.
