摘要:
为了研究遮帘式板桩码头结构中土压力的传递机理,采用模型试验分别模拟遮帘式板桩码头结构和单锚式板桩码头结构的开挖过程,分析2种板桩码头结构中不同断面上土压力的变化规律.试验结果表明:从2种板桩码头结构的弯矩分布和水平变形来看,结果与原型结构的变形形式相符;码头开挖后,在拉杆拉力相近的情况下,遮帘式板桩码头结构中前墙水平位移和弯矩小于单锚式板桩码头结构;当前墙上土压力减幅相同时,遮帘式板桩码头结构中前墙水平位移也小于单锚式板桩码头结构.遮帘式板桩码头结构体现了很好的遮帘效果.在远离遮帘桩的位置,2种结构的土压力减幅都很小,可忽略不计.遮帘式板桩结构中,越靠近前墙,断面上的土压力减幅越大.
Abstract:
The model experiments are adopted to simulate the excavation process of the sheet-pile barrier wharf structure and the single anchored sheet-pile wharf structure. Through the analysis of two kinds of soil pressure on the sheet-pile wharf structure in different cross sections, the pressure transfer mechanism of soil earth is revealed. The experimental results show that the moment distribution and the horizontal deformation of two kinds of structures are similar to the deformation form of the prototype structure. While the rod tensions are similar, the horizontal displacement and bending moment of the front wall of the sheet-pile barrier wharf structure after excavation are smaller than those of the single anchored sheet-pile wharf structure. While the decreased amplitude of soil pressure on the front wall is the same, the horizontal displacement of the front wall of the sheet-pile barrier wharf structure is also smaller. Thus, it can be seen that the sheet-pile barrier wharf structure has good barrier effect. Away from the barrier pile position, the decreased amplitude of soil pressure of two kinds of structures is small and can be ignored. The closer to the front wall, the greater the decreased amplitude of soil pressure of the sheet-pile barrier wharf structure.
