Abstract

Abstract

In order to effectively improve the comprehensive management level of geological disasters in oil and gas pipelines, the authors in this research adopted engineering geological analysis principles and methods to conduct a detailed analysis of the retrogressive landslide caused by gully source tracing, and formulate appropriate comprehensive management countermeasures, combined with the geological environmental conditions of G132 landslide in China-Myanmar Pipeline (Myanmar Section) and the continuous deformation characteristics of the landslide in recent years. Three deformation stages of the retrogressive landslide caused by gully source tracing were basically divided through the analysis of the landslide evolution model, including gully incision and slope deformation stage, the retrogressive sliding deformation stage and the overall sliding deformation stage. The practical and feasible integrated control counter measures of “zoning and graded retaining, source blocking and bed consolidation, and combination of interception and drainage” were put forward, based on the deformation characteristics, formation mechanism and evolution model of the landslide. This strategy has been implemented step by step, and it has passed through many flood seasons with good engineering results. This research could provide certain references for similar projects related to retrogressive landslides caused by gully source tracing in the future and has great significance in controlling and reducing geological disasters of oil and gas pipelines and protecting the safe operation of China Myanmar Pipelines.
