Abstract:

This paper deals with a pipeline section on both sides of Douglas Pass in west Colorado. Landslide activity in the area has been causing considerable problems and disruptions of the pipe integrity. The pipe owner decided to implement certain mitigating measures that would enable to maintain the pipe at its present location but to minimize the risk of the failures. The scope of such work has been to predict a potential pipe failure at specific locations and to implement early mitigating measures to prevent it. The work discussed included certain geotechnical studies to identify individual landslides, installations of various monitoring methods such as inclinometers, extensometers and vibrating wire strain gages and continuous monitoring of critical sections.
