Abstract：Of marine geological disaster factors,the submarine landslides do not occur frequently,but the disaster losses caused by them are often more serious.The slope stability can be comprehensively influenced by many factors and the influence degree of these factors is different.Therefore,the sensitivity analysis of factors influencing the slope stability has always been one of the important aspects at home and abroad.By tak-ing the slope of the Caofeidian deep groove as the research object,the factors influencing the stability of underwater slope are analyzed.By using the software Geo-Slope,a sin-gle-factor sensitivity analysis is made of intrinsic sensitivity factors such as cohesive strength,internal friction angle,density and falling gradient and three external sensitive factors including seismic coefficient,additional load and wave height.The results show that the internal friction angle of the intrinsic sensitivity factors is the most sensitive and the seismic coefficient of the external sensitive factors is the highest in sensitivity.This sensitivity analysis will provide the basis for the control program of submarine land-slides.
