摘　　要：为了确定方舱在爆炸荷载作用下的极限承载能力和承受0．05MPa的冲击波荷载需要采取的加固措施，采用ANSYS MECHANICS／LS-DYNA有限元软件对某整体大板方舱的静、动力响应进行了数值计算。结果表明，舱体的静、动力极限荷载分别为0．01125MPa、0．020MPa；通过五种加固方案的比较和优选，得到了方舱的最佳加固方案，其成果可为加固设计方舱的抗爆试验方案提供参考。In order to decide the limit bearing capacity of the square cabin under the effect of explosive load and the reinforcement measures needed to be adopted when the square cabin suffered 0.05MPa blast load,the numerical calculation for the static and dynamical responses of a certain whole square cabin is conducted by using ANSYS MECHANICS/LS-DYNA limit element software. The results show that the static and dynamical limit loads of cabin are 0.01125MPa and 0. 020MPa respectively. Through comparing and optimizing five reinforcement projects, the best reinforcement project of square cabin is found, and its results will contribute to the anti-explosive test project for reinforcement design of cabin.
