摘要
Abstract
The right abutment shoulder of the Wudongde Hydropower Station dam features a natural K25 giant karst shaft.In order to improve the arch-end stress transmission effect and enhance the overall safety of the dam-foundation system,engineering measures were adopted to excavate and backfill with Roller Compacted Concrete(RCC)below the dam crest elevation of 988 meters,supplemented by grouting consolidation.Monitoring data after the treatment showed that the deep deformation of the dome and surrounding rock mass,as well as the stress on the support anchors,were minimal.The backfilled concrete was primarily under compression,tightly integrated with the surrounding rock,and its temperature had stabilized.There was no significant seepage pressure around the shaft,and all monitoring indicators were normal.The treatment effect of the karst shaft was excellent.关键词
