Abstract
An ancient landslide is situated in the vicinity of one of the two reservoirs of a pumped storage power project. Ground movements of the landslide accelerated following the construction of the reservoirs about thirty years ago. Though at a relatively low rate of movement, the active landslide jeopardizes the serviceability of transmission lines and roads traveling through the landslide area. The landslide also poses a potential threat to the adjacent reservoir. Based on long-term monitoring and thorough engineering investigations, remedial measures were developed and implemented in an effort to stabilize the active landslide. Different facets of the remediation construction were proved to be challenging. While the remedial construction appears to have been effective, continuous monitoring of the landslide is believed to be indispensable in assessing the performance of the remediation. This paper discusses monitoring techniques, historical monitoring data, the mechanism of the landslide and the methodology of the adopted remediation.
