| 摘 要： | 针对航道整治工程中软体排的铺排施工过程,分析软体排在静水沉放过程中的受力,利用非线性有限元方法进行模拟计算,以分析排布的实际受力大小及受力分布。结果表明,排布受力状态沿宽度方向上的分布具有明显不均匀性,须在软体排排布设计及实际铺排施工时加以重视。

| Abstract: | Based on the theoretical analysis for flexible mattress during sinking in hydrostatic water,non-linear FEM were used to analyze the tension force and its distribution on flexible mattress.The results from non-linear FEA reveal that the tension forces subjected by flexible mattress are in the condition of uneven distribution,which has to be paid attention in the mattress design and the practical engineering project application. |
