Long-Term Performance of Landslide Shear Piles
This paper presents a case history of long-term performance of shear piles which were constructed to stabilize a landslide on the Oregon coast. The shear piles consist of cantilevered, reinforced concrete drilled shafts designed to resist shear and bending moment demands resulting from loading by the landslide. Three shear piles were instrumented with inclinometer casings attached to the rebar cages. These inclinometers have been monitored for over 8 years since construction, which has provided valuable data regarding the long-term performance and behavior of shear piles. Other parts of the landslide are also instrumented with inclinometers, which have also been concurrently monitored, to provide data on the effectiveness of the shear pile stabilization. Using the deflected shape of the inclinometer in the shear pile, structural analyses were performed to estimate the actual shear and bending moment demands in the shear pile. The inclinometer data appear to validate the effectiveness of the shear piles. This performance evaluation provides insight into the mechanism of the passive shear pile system and the interaction between the shear piles and the landslide.
