STUDY ON ENGINEERING-GEOLOGICAL CONDITIONS FOR LANDSLIDE AT BADU K343 SECTION NANKUN RAILWAY AND CONTROL ON IT

摘要: An integrated geological and geophysical investigation suggests that the landslide at Badu K343 occurred because top of strong weathering zone on sandstone is rich in kaolin other minerals which became liguid layer by water saturation after torrential rain caused loose sediments to undergo gravity instability. The body about 20 m thickness, 30 thousand 2 cover area, 600 3 slip volume. Based conditions, a proposal building piles ditches for control suggested.
