充填管袋筑堤施工期仿真模拟

摘要

In this paper,we build a numerical model of the sea dike of Tiaozini Project to simulate the layered loading process of geotubes by using the software ABAQUS.The results of numerical simulation matches with the site monitoring data very well and it shows an accurate deformation trend.The maximum sedimentation point locates in the middle of the border of sea dike and foundation,with the value of 7.88cm,15% smaller than the monitoring data;the stress distribution is highly consistent with the monitoring data.%针对条子泥大型匡围工程，利用有限元软件ABAQUS建立数值模型对海堤施工期管袋分层加载的筑堤过程进行了仿真模拟。数值模拟结果与现场监测数据较为吻合，变形趋势准确。最大沉降点位于堤坝与堤基交界处，堤坝的中部，数值为7.88cm，比监测数据小15%；应力分布情况高度符合符合监测数据。
