摘要
Abstract
Approximately 80%of the flip bucket foundation at the spillway tunnel outlet of the Bala Hydropow-er Project is situated on a deep overburden layer.Through numerical analysis methods and considering con-struction conditions,structural reliability,and project investment,four schemes-excavation and backfilling,pile foundation,slurry trench wall with frame structure,and overburden consolidation grouting-were analyzed and studied.The most scientifically sound and reasonable treatment method,which best aligns with the project's characteristics,was selected,providing valuable references for the foundation treatment of similar hydraulic structures.关键词
