摘要

拟建的内蒙古获青公路是半干旱山区线路工程的典型代表。公路沿线最主要的地质环境特征是气候条件恶劣、地质条件复杂、岩体破碎、岩堆发育、高陡边坡密布。潜在的地质灾害主要有岩堆失稳、高边坡变形破坏和峡谷路基洪涝灾害。相应的防治措施建议为:绕避I类岩堆;采取优化线路布设与岩堆加固相结合方式处理III、II类岩堆;高边坡常规处理;按不同河段,以适当抬高路面标高,或设置较大过水断面桥涵,并辅以相应防洪措施防治峡谷路基洪涝灾害。
The programming highway from Huogeqi mining area to Qingshang town is a canonically line project in the semiarid region.The rough weather,complex geological conditions,broken rock,development taluses,and densely distributed large and stiff slopes,are the marked engineering geological conditions along the planning route.The potential geological hazard includes taluses failure,large and stiff slopes failure,and the roadbeds drown in gorge regions.Schematic preventions are suggested be keep away from large taluses,optimize route arrangement and root the small taluses,reinforce large and stiff slopes by conventional treatments,with some supplementing projects,elevate the roadbed or bridge over on different reach in gorge regions to avoid the potential waterlog.
