| 摘 要： | 以嘉兴港海盐港区围堤与杭州湾跨海大桥的穿越段为例，采用基于Mindlin应力解的桩伐基础简化分析和三维弹性数值模拟两种方法，探讨了嘉兴港海盐港区围堤对杭州湾跨海大桥桩基产生的负摩阻力和侧向推力．通过分析比较，简化分析方法与弹性三维数值模拟结果吻合较好，说明应用简化分析方法得出的结果也可作为桩承式围堤结构基础设计的参考依据．

| Abstract: | Using a simplified method based on Mindlin stress solutions as well as 3-dimensional numerical analyses with elastic constitutive models,the negative skin friction and lateral push on the piles for the Great Trans-oceanic Hangzhou Bay Bridge due to intersecting Jiaxing Port embankment are evaluated in this paper.It indicates that the simplified method based on Mindlin stress solutions can be roughly adopted to assess the negative skin friction and lateral push on piles due to adjacent pile foundations as it... |
