中文摘要:
      为研究布置在河道中的桩群、连续墙对河道水流的影响,采用二维数值模拟的方法,以某城市河涌改造工程为例,对3种不同桩间距的桩群方案和连续墙方案在一定洪水情况下对河道水流的影响进行对比分析,连续墙方案或桩间墙方案在流态影响、壅水高度及运行管理等方面优于桩群方案,可为类似工程中桩群的优化方案提供借鉴。
英文摘要:
      Cross-river and bridge projects are becoming more and more. In order to study the effect of the pile group and its optimized structural arrangement on river flow, two-dimensional numerical simulation method is used to transform a river surge project in a city. Three different spaces of pile groups and continuous wall schemes on the river flow are made contrastive analysis under certain flood conditions. The continuous wall scheme and the pile wall scheme are better than the pile group scheme in flow state, the height of dredging and the operation management aspects. The conclusion can be considered as an optimization program for the pile group in similar projects.
