Abstract: In the process of pipeline engineering construction, a lot of high fill slope engineering has to be carried out to deal with the restriction of station site selection. Before the station is constructed, the fill slope shall be treated in advance, so that the slope stability can meet the requirements of subsequent station construction. The Anning initial station of Yunnan Product Pipeline is located in the area of fill engineering whose maximum fill height is 30 m. If oil tanks and pipelines are installed in the fill area, this area shall be treated to meet the high-level standard. In this paper, the slope gradient program, the anti-sliding pile program and the geotextile reinforcement program were compared from the aspects of advantages and disadvantages, and it was ultimately determined to adopt geotextile reinforcement technology to treat the fill slope. Then, the design idea, calculation process and construction requirement of this fill slope engineering were illustrated. It was successfully applied on site with good economic and social benefits. It provides the valuable reference for the construction of following similar engineering.
