摘　　要：结合西藏林拉高等级公路勘察设计及施工实施过程中沿线河流侵蚀及路基水毁、隧道涌水及软岩大变形、泥石流、滑坡等主要不良地质特征进行阐述,对青藏高原川藏走廊沿线主要不良地质有更深入的认识,并以此提出川藏走廊沿线类似不良地质的防治对策。Combined with the characteristics of main adverse geology such as river erosion,subgrade water damage,tunnel water gushing and large deformation of soft rock,debris flow and landslide during the survey,design and construction of the first Nyingchi—Lhasa high-grade highway in Tibet,a deeper understanding of the main adverse geology along the Sichuan—Tibet corridor in the Tibetan Plateau has been obtained and the prevention measures of similar adverse geology along the Sichuan—Tibet corridor has been put forward.
