码头工程对山区河道水位影响的水槽试验研究

Test study on impact of wharf structures on water level in mountainous waterways

为了探索在山区河道中修建码头对工程所处河段水位的影响,采用理论分析与物理模型试验相结合的方法,对工程所处河段最大水位壅高值与壅水范围进行了分析研究。通过对物理模型试验得到的37组次不同条件下的试验数据进行分析,得出了计算码头工程相对最大水位壅高值的关系式,验证了工程上游壅水范围理论计算公式的可行性。研究成果可为山区河道码头工程建设管理和设计提供参考。

In order to study the influence of building wharf structure in mountainous waterways on water level in the affected channel,we study the relative maximum backwater level as well as its extent caused by wharf structures based on the method of theoretical analysis integrated with model test.Based on the analysis on the data from 37 sets of model test in different conditions,we obtain an expression for the relative maximum backwater level caused by wharf structures,and verify the feasibility of some calculation formulas for upstream backwater extent.The results provide theoretical foundation for the planning and design of wharf structures in mountainous waterways.
