借助大型通用有限元软件ABAQUS,以京唐港区32#通用散货泊位为工程实例,根据现场原型观测试验,对代表性断面进行选取、简化,建立相应的二维模型进行数值模拟计算,给出了遮帘式板桩码头开挖过程中变形形式的模拟方法,并将数值模拟结果与现场原型观测实验数据进行了对比。研究结果表明:1在不考虑剩余水头和堆载影响的情况下,数值模拟计算的变形结果与现场原型观测的变形结果比较接近,基本可以反映这种新型结构构件在水平向与竖向的变性特性;2两者对比的结果验证了本文所提出的开挖模拟方法的合理性。
With the help of large general finite element software ABAQUS, taking the 32 # general cargo berth in Jingtang Port as an example, according to the field prototype observation and experiment, the representative sections are selected and simplified, and the corresponding two-dimensional model is established for numerical simulation. A simulation method of deformation in the process of excavation of blind piled wharf was put forward, and the numerical simulation results were compared with the experimental data of on-site prototype observation. The results show that: 1 Without considering the influence of residual head and stack, the deformation results of numerical simulation are close to the deformation results of on-site prototype observations, which basically reflect the horizontal and vertical degeneration of this new type of structural component The results of the two tests verify the rationality of the proposed excavation simulation method.
