Abstract:In order to strengthen the application of strength reduction method in submarine landslide analysis,the finite element model from the secondary development of software ABAQUS is used to analyze and evaluated the stability of submarine slopes based on the project of "Liwan 3-1 gas field's adverse geology risk evaluation",and then on this basis,a lot of changes on the parameters are made to search the nature of seabed slope stability and impact of soil properties on seabed slope stability.This secondary development module is simple in operation,accurate in calculation and precise in safety factor.The calculation results show that the submarine slope gradient,soil friction angle and undrained shear strength would play a decisive role in the stability of submarine slope,but the soil density would have little effect in that.
