| 摘 要： | 川气东送管道工程是国家跨区域重大天然气管网工程，路线全长1559km。管道沿线地质环境条件复杂，地质灾害异常发育。笔者在对沿线地质灾害调查的基础上，开展了地质灾害危险性评估，并提出了具体的对策建议，主要取得了以下认识：1）川气东送管道沿线地貌类型众多、活动构造复杂、岩土体工程地质条件及水文地质条件差异较大，人类工程活动强烈，地质灾害异常发育。2）研究区突发性地质灾害与缓变性地质灾害并存，共发育隐患点260处，其中崩塌88处、潜在不稳定斜坡74处、滑坡52处、地面沉降36处、泥石流10处。3）地质灾害危险性大的地质灾害点共16处，危险性中等的9处，其余为危险性较小的地质灾害隐患点。4）提出了各类地质灾害点的防治对策建议，为管道工程沿线地质环境安全提供了基础地质依据。

| Abstract: | The Sichuan-to-East Gas Transmission pipeline is one of the most important natural gas transmission pipelines in China and the route length is 1559km.Through the geological hazards investigation and assessment along the pipeline,the author concluded that:1) There are many terrain types and geological strures along the pipeline where the geotechnic and hydrogeological characters are different,in addition to the strong human engineering activities,the geological hazards are developing strongly.2) There are 260 pionts of hidden dangers of geological disasters,which collapses were 88,landslides were 52,debris flows were 10,land subsidence were 36 andpotentially unstable slopes were 74 in the study area.3)There are 16 points of the great risk of geological disasters were assessmented,and the risk of moderate were 9.4) By studying each type of geological disaster prevention countermeasures,then put forward the safety of the pipeline project along the geological environment on the basis of basic geological and technical. |
