某高流速大泄量溢洪洞出口挑坎基础处理研究OA
Research on foundation treatment of the flip bucket at the outlet of a high-flow,large-discharge spillway tunnel
巴拉水电站溢洪洞出口挑坎基础约80%置于深厚覆盖层上,通过数值分析方法并结合施工条件、结构可靠性及工程投资对开挖回填、桩基、框格式地下连续墙、覆盖层固结灌浆四种方案进行分析研究后,选定最符合工程特点、科学合理的处理方式,为类似水工建筑物基础处理工程提供借鉴经验.
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.
