%X Geologists highly concern whether the deformable body on Longpan's right band locate at the upper stream 20 km from the Hutiao gorge could lose the stability suddenly or not after the Hutiao gorge reservoir is impounded.Based on the shape,buried depth,scale and the border of the deformable body determined by seismic refraction exploration,we identify the reflective wave,surface wave,and refraction wave further from the shot gathered data acquired with refraction exploration,then use them to interpret the interior structures of the deformable body and to calculate elastic and non-elastic parameters.With decay coefficients of surface wave and refraction wave,the ratios are calculated between non-elastic parameter and the elastic parameter of shear wave and P wave in the deformable body,which are 0.000184 and 0.000144,respectively.We infer that the deformable body will distort steadily caused by non-elastic deformation or slide after the reservoir is impounded,because the pore pressure will be increased and the shear strength will be decreased after the pore in the deformable body is water-bearing enough,but we can not make sure whether the stable distort or sliding could cause a non-steady slide suddenly or not because we don't have enough data to prove it.
