土体参数对遮帘式板桩码头结构侧向变形的影响

文中通过ABAQUS有限元数值软件建立遮帘式板桩码头的三维数值模型,研究不同土体参数对遮帘式板桩码头结构侧向变形的影响。研究结果表明,土体的弹性模量对结构的整体稳定性影响较大,随着弹性模量的减小,前墙和遮帘桩水平位移逐渐增大,减小的愈多,变形愈明显;土体内摩擦角和粘聚力对遮帘式板桩结构物的位移变形影响主要集中在结构物的中上部,对结构物底部的位移变形影响较小,随着内摩擦角和粘聚力的增大,前墙和遮帘桩中上部的水平位移逐渐减小,发生最大变形的位置基本不变。

NUMERICAL SIMULATION STUDY OF SOIL PARAMETERS ON LATERAL DEFORMATION OF COVERED TYPE OF SHEET PILED WHARF

In this paper, the three-dimensional numerical model of the blind-type sheet pile wharf is established by ABAQUS finite element numerical software, and the influence of different soil parameters on the lateral deformation of the curtain-type sheet pile wharf is studied. The results show that elastic modulus of the soil affects the overall stability of the structure. As the elastic modulus decreases, the horizontal displacement of front wall and covered sheet pile increases gradually, and the more the reduction, the more obvious the deformation. The influence of internal friction angle and cohesion on the displacement is mainly located in the middle and upper part of the structure, and has little effect on the displacement and deformation at the bottom of the structure. With the increase of internal friction angle and cohesion, the horizontal displacement of decreases gradually and the position of maximum deformation is basically unchanged.
