SPECIAL GEOLOGICAL COLLAPSE AND WATER GUSHING IN A MOUNTAIN HIGHWAY LONG TUNNEL ANALYSIS AND TREATMENT
Due to the constraints of terrain conditions on mountainous highways,tunnel schemes are often used to cross mountains during the route selection process.The terrain of mountainous highway tunnels is undulating and complex,facing unfavorable geological conditions such as faults,karst,high ground stress,and gas.Geological disasters such as water inrush,collapse,large deformation,and rock burst may occur.Improper treatment not only causes safety and quality accidents,increases investment,affects construction period,and later operation,but also has adverse social impacts.Taking a long highway tunnel in a certain mountainous area as an example,this paper explores the causes and treatment measures of collapse and water inrush in highway tunnels under complex geological conditions.
