THE USE OF GEOPIER? PLATE PILES? TO RESIST SLOPE INSTABILITY

摘要

Civil engineers are often required to address slope stability issues for new and existing developments, roadways, bridge embankments and natural slopes. When excessive slope movement is detected, it is important to find a solution that will stabilize the slope quickly, economically and with no impact to the users of the sloped infrastructure and adjacent properties. The Geopier SRT? system provides slope stabilization of shallow failures using driven steel Plate Pile? elements installed vertically into the unstable slope in alternating arrays. Plate Pile elements are low-displacement steel sections that leave no exposed steel upon driving into the ground and do not require post-tensioning. Installation is performed using small, tracked excavators, capable of working on slopes of up to 1H:1V, which allow for the work to be performed directly on the slope with minimal interruption to local residents and/or traffic. This paper will discuss the Geopier SRT system and provide case studies which highlight the various advantages of the SRT system.
