Yuhai Road is the gateway to Yudu Mountain Nature Reserve,and Most of the road is the mountainous section.There are a large number of unstable slopes with broken rock and geological structures.The road was built along the slope without disaster prevention project,so the collapse and landslide hazards often happen.In the past,pedestrians and vehicles have a greater threat although no casualties.This paper describes the characteristics and development of the collapse and landslide hazards along the Yuhai Road.With the introduction of two evaluation projects including susceptibility and harmful levels,the comprehensive evaluation and prevention method of disasters are discussed finally.
