摘　　要：千岛湖配水工程在闲林出口库内设置自由溢流形式调压井,溢流调压井泄水道左侧距离山谷线较近,泄水道顶部及中下部基础出现局部松散土体,基础呈现承载力不足、局部脱空、稳定性差且不均匀沉降等不利情况。结合施工现场及相关工程基础处理经验,通过调整泄水道纵向坡比、回填混凝土、增设盲沟及延伸锚筋长度等措施,对泄水道进行了结构与基础优化设计处理,优化设计后基础处理得当,使工程施工顺利开展并平稳运行,在施工进度管理、质量把控及成本控制上均具备较好的可行性及借鉴性。The water distribution project of the Qiandao Lake sets up a free overflow surge camber in the outlet of the Xianlin reservoir.The left side of the drainage channel of the overflow surge camber is close to the valley line,and the foundations at the top and middle-and lower-parts of the drainage channel have local loose soil and present unfavorable conditions such as the insufficient bearing capacity,local cavitation,poor stability and uneven settlement.Combined with the foundation treatment experience of the construction site and related engineering,this paper carries out the optimization design of the structure and foundation of the drainage channel by adjusting its longitudinal slope ratio,backfilling concrete,adding blind ditches and extending the length of anchor bars.After optimization design,the foundations is properly treated,making engineering construction carry out smoothly and run smoothly,which has good feasibility and reference in construction schedule management,quality control and cost control.
