摘　　要：In order to identify the threat of reservoir bank landslide to dam safety and reduce the risk of dam failure,impact factors of the landslide are analyzed.The concept of landslide risk degree is put forward to measure the threat of landslide to dam safety.The monotony of the landslide risk assessment function which changes with different affecting factors is analyzed qualitatively.Based on gene automatic programming,a data mining model of the landslide risk assessment function is constructed combined with impact factors of reservoir bank landslide on dam safety.And the assessment function of landslide risk has been excavated and established according to practical project information,which provides a valuable reference for analyzing the impact of landslide on dam risk.In order to identify the threat of reservoir bank landslide to dam safety and reduce the risk of dam failure,impact factors of the landslide are analyzed.The concept of landslide risk degree is put forward to measure the threat of landslide to dam safety.The monotony of the landslide risk assessment function which changes with different affecting factors is analyzed qualitatively.Based on gene automatic programming,a data mining model of the landslide risk assessment function is constructed combined with impact factors of reservoir bank landslide on dam safety.And the assessment function of landslide risk has been excavated and established according to practical project information,which provides a valuable reference for analyzing the impact of landslide on dam risk.
