摘要
借助离散单元法的数值仿真对堤岸护岸技术开展研究,对沿海抛石的级配、粒径大小和形状、抛石高度、抛填速率等关键技术参数进行优化分析。通过数值模拟方法,提出堤岸抛石的抛填机理,采用PFC模拟抛石抛填形成堤岸的施工过程及施工控制条件,分析得出堤岸抛填抛石的影响因素。
Based on the research on the embankment bank protection technique with the discrete element method to undertake numeric simulation,the study undertakes the optimal analysis of some key technical parameter,including the gradation of the riprap along the sea,the sizes and shapes of particle diameter,the riprap height,and riprap and filling rate,points out the riprap mechanism for the throwing by the numeric simulation method,adopts PFC simulation riprap filling to form the condition for the construction process and construction control at embankment,and concludes the influential factors of riprap at embankment.
