某电厂防波堤及航道工程设计优化

Optimizing Design of Breakwater and Channel Project in Power Plant

某电厂北防波堤及航道工程原"大开挖"方案挖泥区出现基岩层,若炸礁清岩耗资巨大,因此需对原设计方案进行调整和优化,并需要通过委托试验单位进行整体物理模型试验对优化后的设计方案进行验证。通过的物理模型试验研究了在原地形、原地形上开挖航道、"大开挖"以及原地形上开挖航道+优化4种方案下各工况北防波堤及岛堤轴线处的波浪分布情况。试验的结果证明了在原地形上开挖航道的现状下对航道边坡进行削坡处理,可有效降低岛堤及北防波堤处的波浪要素并确保工程安全,该方案简单易行且可节省工程投资,对类似的实际工程项目具有借鉴意义。

The bedrock layer is found in original ＂Large-scale dredging proposal＂dredging area of a power plant north breakwater and channel project,which be rid by reef blasting will be too costly.The project was needed to adjust the original design and optimization.And the physical model experiment on the optimized design to verify the new project.This paper research the wave distribution in north breakwater and island breakwater center line by physical model test under different conditions as original landform,dreading channel in original landform,＂Large-scale dredging proposal＂ and dreading channel in original landform＋ optimize program.The result indicates the cut slope disposal on channel side slope under the dreading channel in original landform condition can decrease the wave parameter in island breakwater and north breakwater thereby insures the project safety.The method is simple and investment can be saved.It’s referential value of the similar projects.
