【摘要】 分离卸荷式板桩码头结构主要由前墙、锚碇墙、拉杆以及卸荷平台体系组成,通过卸荷平台体系承载码头上部结构荷载,以达到减小前墙荷载、加大港池开挖深度的效果。对这种新型码头结构堆载过程进行的数值模拟是码头数值模拟的基础。通过FLAC3D软件进行数值分析,探讨堆载过程中,分离卸荷式板桩码头的受力与变形特性,以及码头结构上土压力分布规律。通过与原型观测数据和离心模型试验结果对比,验证堆载模拟方法的合理性。更多还原

【Abstract】 The sheet-pile wharf with separated relief platform is mainly composed of the front wall, the anchorage wall, the tie rod and the unloading platform system. The system bears the load from the wharf upper structure,which can reduce the front wall load and increase the excavation depth of the basin.Numerical simulation for the stacking process of this new type of wharf structure is the basis of the numerical simulation for the wharf.Numerical simulation by software FLAC3 D is carried out to discuss the stress and deformation characteristics and the earth pressure distribution of sheet pile wharf with separated relief platform during excavation and stacking.Based on the comparison between results of prototype observation data and centrifugal model test,the rationality of the stacking simulation method proposed here is verified.更多还原
