摘　　要：地质灾害是天然气管道建设及运营来的一个重大风险因素,通过对山东泰青威线天然气管道实地调查,发现89处地质灾害点以及台田地水毁、坡面水毁、河沟道水毁灾害、不稳定斜坡、崩塌(危岩体)和人类工程活动等6种地质灾害;通过分析沿线各类地质灾害特征、分布规律,以保护管道安全为根本,同时考虑经济节约和新技术应用,提出了相应、可行的监测预警和削坡、挡墙、回填、喷浆等具体工程治理措施,对管道安全运营及施工具有较大的意义和指导作用。Geological hazard is a major risk factor in the construction and operation of natural gas pipeline.Through the field investigation of natural gas pipeline in Tai’an-Tsingdao-Weihai Line of Shandong Province,89 geological hazard sites and 6 kind of geological hazards such as platform water destruction,slope surface water destruction,water disaster in river channel,unstable slope,collapse(dangerous rock mass)and human engineering activities were found;By analyzing the characteristics and regularities of distribution of various geological hazards along the route,taking the protection of pipeline safety as the fundamental principle,considering the economic saving and the application of new technology,the corresponding and feasible monitoring and early warning and concrete engineering treatment measures such as slope cutting,parapet,backfill and grouting are put forward,which is of great significance and guidance to pipeline safe operation and construction.
