| 摘 要： | 根据坝址的地形地质条件及工程对库区淹没的敏感性，经分析比较，老口航运枢纽泄洪建筑物选择13孔单孔净宽22m的大孔口式泄水闸坝，溢流堰型为低坎宽顶堰，经模型试验验证，堰型合理，泄水闸坝泄流能力满足设计要求。对于承受弧门总推力为30600kN的闸墩，采用预应力结构，经有限元法分析计算，中、边闸墩厚度分别为3．2m、4．5m，配筋在合理的范围，结构安全能够满足。

| Abstract: | According to the topographical and geological conditions of dam site,taking into account the sensitivity of the project to inundation,after analysis and comparison,the relief structure of Laokou Complex was designed as a sluice dam accommodating 13 gates,each with net width of 22m,low sill and broad-crest weir.The results of model test demonstrated the selected weir type is proper and the discharging capacity conforms to the design requirements.Pre-stressed structure was adopted for the pier withstanding to... |
