G317线汶川至马尔康段公路崩塌滑坡灾害危险性评估

摘要

为减少公路工程建设项目和地质灾害之间的相互影响，工程建设之前必须对工程建设用地存在的地质灾害进行评估。结合国道317线汶川至马尔康段公路改建工程的特点，对工程遭受或工程建设可能诱发加剧的滑坡和崩塌灾害发生的可能性作了分析，并提出相应的防治对策，为拟改建的公路建设提供指导性建议。%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.
