Model experiment study on soil pressure characteristics of sheet-pile barrier wharf structure
摘要
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 distribu-tion 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 pres-sure on the front wall is the same,the horizontal displacement of the front wall of the sheet-pile bar-rier 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 de-creased amplitude of soil pressure of the sheet-pile barrier wharf structure.关键词
