| A i med at the Badu (K343) I arge seale I andslide in the NanKun railway, geophysical exploration techniques such as Seismic Reflection of High Resolution and Geological Radar are appi ied to detect the geologic characteristics of the landslide mass including 3D-conformation, perimeter, geometric parameters, si ippage pattern and distribution of displacement field in this dissertation. Besides, acoustic method is used for detection of the former anti-slide piles and potency losing causations of the piles are analyzed and the sound geological conditions for upgrade of the piles are ascertained by the above investigations.Based on the geometric parameters and characteristics of deformation revealed, landslide mechanism has been analyzed and Limit Equi I ibrium Method has been carried out for stability evaluation of the Iandslide mass. A 3D mechanical model of the I ands Iide mass has been establi shed and a f ormu I a for stabilitycalculation has been further deduced, which has been adopted for practical use of the upgrade project in the Badu(K343) landslide and is well grounded on the fact.
