Sensitivity analysis of slope stability based on uniform design

In sensitivity analysis of slope stability,the number of test times and test effectiveness are dependent on the test approaches.The application of uniform design can effectively reduce the test times and improve the test effectiveness.As a case study,the sensitivity analysis of a homogeneous soil-slope stability is carried out with density of soil,angle of internal friction,cohesion,angle of slope and acceleration of earthquake are selected as the influencing factors for test design.It is found that the cohesion,the angle of slope and the angle of internal friction are sensitive,but the density of soil and acceleration of earthquake are insensitive.The conclusion can be used in the comprehensive remedy,security monitoring and disaster forecasting of slope.
