不均匀沉降影响下的方块码头胸墙内力有限元分析

针对方块码头普遍存在的不均匀沉降问题,进行不均匀沉降影响下的胸墙内力数值分析。通过有限元软件ANSYS的静力求解模块及接触分析方法,计算得出不均匀沉降影响后在自重及使用期荷载作用下的胸墙内力。结果表明,不均匀沉降影响后的方块码头胸墙内力将显著增加。因此,必须采取一些设计和施工的措施来减小不均匀沉降对方块码头胸墙的影响。

Finite element analysis of breast wall internal force for concrete block quay wall under effect of non-uniform settlement

Numerical analysis of the internal force of breast wall is performed to the problem of non-uniform settlement commonly existing in the concrete block quay wall.According to the static and contact analysis method of the finite element software ANSYS,we calculate the internal force of breast wall under the action of self-weight and operation loads.The analysis results show that the internal forces of breast wall increase significantly by the effect of non-uniform settlement.Therefore,some design and construction measures should be considered to reduce the effect of different settlement to the capping beam.
