The glacier melt-water with continuous high temperature and the local heavy rainfall with short duration together promote the occurrence of floods and debris flows along the Gaizi River and its tributaries. More important, due to unreasonable designing and inappropriate construction of the highway, the washout disasters along the highway have happened and caused heavy damage. The research results can provide reference for highway design maintenance and management, and provide the guidance for highway washout prevention.
