摘　　要：通过对大兴安岭新林区林海～宏图公路沿线的实地调查,详细介绍了沿线区域的地质环境条件,同时归纳总结了沿线崩塌灾害的分布特征、规模及形成原因。根据崩塌体的不同破坏形式,选取典型危岩体采用定性和定量相结合的方法对其稳定性进行了综合评价。在全面考虑稳定性分析结果及公路边坡地形地质条件下提出了沿线崩塌的具体防治措施。Through field survey along the Linhai-Hongtu Highway in the new forest zone ofDaxinganling, geological and environmental conditions along the line are described in detail. Alsodistribution characteristics, scale and causes of collapse hazard are inducted and summarized. According todifferent failure modes of collapse, the stability of selected typical dangerous rocks is comprehensivelyevaluated both qualitatively and quantitatively. Concrete prevention measures for collapse along thehighway are proposed based on full considerations on stability analysis results to dangerous rocks,topographical and geological conditions of the highway slope.
