疏浚工程淤泥质土质岸坡开挖方案优化

Optimization of excavation scheme for silty soil bank slope in dredging project

以天津临港经济区T7、T8、T9区补吹填工程为例,对岸坡特点和施工区土层结构进行分析,通过对传统施工工艺进行优化,使施工船舶能够高效地进行岸坡开挖施工。对施工过程进行阐述,为复杂地质条件下超长水下岸坡开挖工程提供解决方案。总结施工经验,进一步优化绞吸式挖泥船施工工艺。

Taking the reclamation and filling project of T7,T8,T9 area in Tianjin Port-vicinity Economic Zone as an example,we analyze the characteristics of bank slope and the structure of soil layer in the construction area.By optimizing the traditional construction technology,we realize the efficient excavation construction of the bank slope by construction ships.Through the detailed introduction of the construction process,we provide a solution for the excavation of super long underwater bank slope under complicated geological conditions.We also summarize the construction experience to further optimize the construction technology for the cutter suction dredger.
