抓斗式挖泥船施工方法及挖槽设计

摘要

With its deep dredging,strong adaptability,and large excavation volume,and or so,the grab dredger is widely used in the dredging works.By learning about the technical specification of dredging engineering construction,it’s indicated that construction method of the grab dredger,channeling design,and selection of channeling dimensions play a great role in maintaining channel stability.The calculation method for stable cross-section of the chamfer is applied to the channeling design in the channel dredging works of Caofeidian District.%抓斗式挖泥船以其挖深大、适应性强、挖掘量大等特点，被广泛应用于疏浚工程中。通过学习疏浚工程施工技术规范，了解到抓斗式挖泥船的施工方法、挖槽设计以及挖槽尺寸的选取对于维护航道稳定性具有重要意义。掌握了挖槽稳定断面的计算方法，并将其应用于曹妃甸区航道疏浚工程挖槽设计中。
