| 摘 要： | 滇藏公路类乌齐-俄洛桥段地质灾害发生频繁,长期以来一直严重影响了该段公路的正常通行。经实地调查研究发现,沿线存在崩塌、滑坡和泥石流等7类地质灾害,共有各类灾害点48处。为使该段公路改建工程的顺利进行,减少地质灾害对改建后公路的危害,文章结合地质环境条件和灾害特征等对全段地质灾害进行了危险性现状评估和预测评估,运用灾损率法和风险性区划法将评估区划分为7个区,并对这7个区进行了地质灾害危险性综合评估、建设场地适宜性和防治工程重要性分级。经综合评估发现,地质灾害危险性大的地区主要分布在地质条件差的高山峡谷地带,危险性小的地区主要分布在地质条件好的宽谷和山岭地带。最后提出了目前青藏高原地区公路地质灾害危险性评估中存在的问题。 |

| Abstract: | The geological hazards occurred frequently from Leiwuqi to Eluoqiao,the Yunnan-Tibet Highway,which influences the traffic a lot.We found that there 48 geological hazards in this section,including collapses,landslides and debrisflows etc. This paper preliminarily evaluated the risk of geological hazards at present and in the future reconstruction engineering through analyzing the geological environmental factors and hazardous features.Furthermore,the integrated evaluation of the risk on geological hazards,the feasibility of rebuilt field and the classification of hazards prevention of 7 sections in the studied region are evaluated respectively by using the hazardous losing index and hazardous classification methods,which are important for future highway rebuilding and hazards prevention.The result of the assessment basically accords to the field investigation.Some suggests about the risk evaluation of geological hazards in the QinghaiTibet Plateau are put forward and discussed in the end of the paper. |
| Keywords: | the Yunnan-Tibet Highway geological hazards risk evaluation the feasibility of rebuilt field prevention engineering |
