Parameter sensitivity analysis of slip zone based on orthogonal experiment

Based on studing the Shuichang iron mine landslide, according to the research on geology condition, the paper studied sensitivity of parameter by using orthogonal experiments, taking internal friction angle, cohesive strength and bulk density as experiment factors, and taking safety coefficient of slope as experiment target. In experiments, simplified Bishop, accurate Janbu and Sarma were adopted to calculate safety coefficient, and range analysis, trend analysis and variance analysis were adopted to study parameter sensitivity of slip zone.WT
