墙前梯形截面有限土体的板桩码头结构设计

Structural design of sheet pile quay wall affected by trapezoidal-cross-section finite soil body

墙前为梯形截面的有限土体的板桩码头受土坡的影响,其土抗力会与墙前为半无限缓坡时存在一定差异。采用岩土有限元软件PLAXIS进行建模,模拟其在陡坡上板桩码头的受力,并对比其与墙前土体半无限水平时板桩结构内力的差异,总结墙前梯形截面有限土体的板桩码头内力计算与结构稳定的设计规律。

Under the influence of the slope, the earth resistance in front of the sheet pile quay wall caused by the trapezoidal-cross-section finite soil body is different from that in the half-space situation.Adopting the finite element software PLAXIS, we establish the model to simulate the stress on the sheet pile wharf which is on the steep slope, analyze the difference of internal forces, and summarize the calculation method of the internal force and the structural stability.
