| 摘 要： | 川气出川管道工程沿线建设用地的自然地理和地质环境条件复杂多样,地质灾害有明显的区域性分布规律:川东、渝中和鄂西为中、低山区,以山地斜坡灾害为主,主要有崩塌、滑坡、泥石流和潜在不稳定斜坡;鄂中、鄂北、豫中和鲁西主要为冲积平原区,以人类活动和采矿引起的地质灾害为主,主要有采空塌陷、岩溶塌陷、地面沉降、塌岸及不良土体。湖北段是本管道工程地质灾害类型最多、灾情最重、危险性最大的地段,在该区段内应对地质灾害危险性大的管线段实施地质灾害监测预警工程,及时、有效地监控可能发生的地质灾害,保证输气管道的安全运行。

| Abstract: | The physi-geographical and geological environment conditions in the area for the pipelines project of transferring gas from Sichuan Province to Eastern China are complex and variable.The geological hazards in the area show the regional distribution pattern.The Sichuan section,the Chongqing section and western Hubei section are mountainous,in which the main geological hazards are landslides and unstable slopes.The northern and middle Hubei section,Henan section and Shandong section are plains,in which the geological hazards are mainly caused by human engineering and mining activities.The main geological hazards are subsidence,collapses of riversides and ill soil.In Hubei section,the geological hazards are the most various dangerous. |
