中文摘要:对某河口水闸的整体设计作了简要介绍,采用空间Biot非线性固结有限元模型分别对其不同工况下地基土、水、水工结构的共同作用进行数值模拟。详细分析了水闸沉箱底板在挡潮工况下的应力分布随地基土固结的变化情况,计算表明在运行期间沉箱底板、闸墩结构是安全的。最后,探讨了桩尖持力层的变化对闸墩底板地基土应力分布的影响。
外文摘要:A brief description is given to the overall design of an estuary sluice. The interaction between soil, water and hydraulic structure under different operating conditions was simulated by using 3-D finite element method. Stress distribution of caisson raft under tiding operating condition was analyzed with consideration of soil consolidation. The calculated result proves the safety of caisson and pier. Finally, the effect of various piles' bearing stratums to stress distribution of foundation was discussed.
