Ganhaizi landslide,about 19790×104m3,is located on the right bank of the Dadu River. Thereare two cracks and one creep body in the accumulation of Ganhaizi landslide. The potential slippage volume ofthe accumulation involved by each deformation body is more than 10×104m3. Cracks 1 and 2 are located inthe middle part of Ganhaizi landslide,while the creep body is situated at the south of the landslide body. Severalsprings are found to the southwest of the staggered platform. The spring flows perennially and keeps limpid inflood period. The accumulation of Ganhaizi landslide is so huge that it may frighten the upstream hydropowerproject (3 km away). Therefore,its stability evaluation is extremely important. The analysis shows that rainstormor earthquake will induce Ganhaizi landslide only partly reactive,but the whole landslide is stable. The areaof potential instability is small,and it cannot surge or dam Dadu River again. In a word,the accumulation ofGanhaizi landslide has little influence on the hydropower project.
