为了适应大吨位深水码头的发展要求,我国自主设计了一种新型板桩码头结构——遮帘式板桩码头,这种新型的码头结构由于前板桩墙后多了一排遮帘桩而使得整个结构的工作机理变得十分复杂。以数值模拟为手段,研究了遮帘桩与前墙的距离以及遮帘桩的刚度对码头工作性状的影响。结果显示,前墙内力受墙桩距离影响很大,墙桩距离决定着遮帘桩能否发挥替前墙挡土的作用,从而决定着结构是否稳定;墙桩距离增大会削弱自身对结构受力造成的影响;遮帘桩刚度越大越能有效的阻止土体变形,挡土效果越好。 In order to meet the requirements of the development of large-tonnage deep-water wharf, a new type of piled-pile wharf structure has been designed in our country. The new wharf structure has a row of blinds behind the front sheet pile wall Making the entire structure of the working mechanism becomes very complicated. By means of numerical simulation, the influence of the distance between the blinds and the front wall and the rigidity of the blinds on the working characteristics of the wharf is studied. The results show that the internal force of the front wall is greatly influenced by the distance between the wall piles. The distance between the wall piles determines whether the blind piles can play the role of retaining the soil for the front wall to determine whether the structure is stable or not. The influence caused by force; the greater the stiffness of blinds pile can effectively prevent soil deformation, the better the retaining effect.
