| 中文摘要: |
| 针对分流挡渣围堰稳定性问题，以两河口水电站为例，采用理论分析与水力学模型试验相结合的方法，选取不同的围堰高程、围堰平台和堰脚防护材料等进行对比试验。通过分析堰面流速、堰脚流速和堰体稳定性，最终确定适合本工程的围堰布置方案及体型。为工程施工组织提供了重要的指导作用并成功实施，研究成果可为类似工程提供参考。 |
| 英文摘要: |
| For the problem of stability of diversion and debris-retaining cofferdams, the Lianghekou hydro-power project is taken as an example to conduct a comparative test by combining theoretical analysis with hydraulic model test and selecting different cofferdam elevations,cofferdam platforms,protective materials at the toe of cofferdam,etc. Through analysis of flow velocity at cofferdam surface,flow velocity at toe of cofferdam,stability of cofferdam body,etc. A cofferdam arrangement plan and body type suitable for the project is finally determined. This plan plays an important role in guiding project construction organization and has been successfully implemented. The study results may serve as a reference for similar projects. |
