摘要
Abstract
There is geologic hazard developed extremely in the section of National Highway 318 from Tongmai to Track Section 105,especially pass by,debris flow in Polonggou Gully;However the treatment is an impossible mission due to the special geological conditions.Therefore,based on the analysis of the genesis mechanism,scale and outbreak frequency of extra large glacial debris flow in Polonggou Gully the scheme of bridge for the line across debris flow was proposed.关键词
