摘　　要：内江至六盘水铁路(以下简称"内六铁路")经过四川盆地向云贵高原过渡地带,沿线地形、地质条件复杂,岩堆、滑坡十分发育,修建难度极大。内六铁路K285滑坡造成中断行车18天,影响较大,需认真研究。本文从发生前的各种动力地质现象入手,结合详细的地质调查,综合钻探、物探成果,从滑坡性质、特征、形成机制等方面对滑坡及受其影响的其他两处岩堆体进行了分析、评价,提出了以下观点:(1)斜坡上岩堆稳定性评价要慎重,新线勘察时尽量绕避。(2)铁路一线工务人员应多与沿线村民交朋友,以便及时了解铁路沿线距线路较远处的险情苗头信息,及时处理。(3)若出现险情,不能有侥幸心理,应及时疏散险情影响范围内的人员。Neijiang-Liupanshui Railway crosses the transition zone from Sichuan Basin to Yunnan- Guizhou Plateau. The landscape and geology are complicated and it is a rock pile and landslide black spot. The construction of the railway was of great difficulty. Neijiang-Liupanshui Railway K285 landslides interrupted 18 days of driving,which needs careful study. This article starts from the various geological phenomena happened before and combines the detailed geologic investigation,the comprehensive drilling,geophysical prospecting results. It analyzes and evaluates the landslide and other two rock pile bodies from landslide nature,characteristics,formation mechanism. These result in the following views：（ 1） The evaluation of rock debris stability on slope must be done carefully,try everything possible must be done to avoid the rock debris on slope when doing a new survey.（ 2） The railway line maintenance personnel should make friends with the villagers along the line in order to know and deal with the danger appeared far from the railway lines in time.（ 3） If dangerous situation occurs,no fluky minds are allowed,all people within the influential zone must be evacuated.
