     The main infiltration channel of excavation loess slope＇ s surface runoff be controlled by loess＇ s joint, the loess joint will gradually develop into a big infiltration channels under the action of rainfall and the destruction of loess slope will be increased. Different excavation slope height of infiltration channel spacing and excavation slope height gaussian fitting relation are concluded through the field geological survey, loess slope joint fissures and infiltration through channel＇s distribution statistics; The rainfall infiltration channel evolution＇ s numerical analysis generalized model be establish according to the infiltration channel distribution relation, the rainfall infiltration channel evolution process and excavation slope damage be analyses under three rainfall condition 40 mm/day, 80 mm/day, 120 mm/day; Pointed out that the rainfall infiltration channel be destroyed under the action of rainfall when Slope high is about 60 m, should pay attention to the infiltration channel severe expansion and controlled while the slope is higher than 60 m. Use field statistics, survey results generalized infiltration channel extension e- volution numerical model is established, can for the engineering geological conditions of the same region under the action of rainfall in loess excavation slope stability failure analysis and prevention and control to provide an effective analysis method.
