摘要
针对吹填土对筒型基础结构工作性能影响的问题,进行三维有限元模拟研究。采用大型通用有限元软件ABAQUS建立筒型基础结构与吹填土相互作用的三维弹塑性模型,模拟在波浪荷载和不同厚度吹填土作用下筒型基础结构各点土压力的变化趋势,揭示筒壁所承受土压力的分布规律以及不同厚度吹填土的影响。该结果为防波堤的筒型基础结构稳定性验算提供了依据。
To analyze the reclaimed soil influence on the working performance of cylinder infrastructure,we apply general finite element software ABAQUS to establish bucket foundation structure and reclaimed soil interaction of three dimensional elastic-plastic model,simulate the wave load and different thickness of reclaimed soil conditions affecting stress size and distribution, and obtain the soil pressure, the bottom of the vertical displacement and the change trend. The results can be used to check computations of stability for the bucket foundation of breakwaters.
