摘要
通过数值模拟和理论分析等手段,利用有限元分析软件ADINA建立了强夯加固吹填土地基动力有限元分析模型,分别在1 000kN.m,2 000kN.m,3 000kN.m和4 000kN.m的夯击能作用下,通过改变夯击点与CFG桩之间的距离,确定强夯对CFG桩的破坏效应的影响因素,确定其安全距离,分析强夯振动下的破坏过程及破坏形态。
A numerical model was established with Adina software to analyze the dynamic consolidation process of dredging filled sand foundation through the numerical simulation and theory analysis.Under the action of the strike of 1000kN·m、2000kN·m、3000kN·m and 4000kN·m and by changing the strike point and the distance between the CFG pile,the CFG pile dynamic compaction of destruction effect factors and the safety distance are determined.The failure process and failure pattern of dynamic consolidation are also analysed.
