Abstract:In order to reduce interaction between highway construction projects and geological disasters, risk assessment of geological hazards of construction using land should be carried out before carring out the projects. Combining with characteristics of reconstruction projects from Wenchuan to Maerkang of G317 Highway , possibility of landslides and avalanches caused by engineering construction has been analyzed, and relative protection countermeasures are put forward as well. It will provide suitable suggestions for planned highway construction.
