摘    要:通过求解弹性状态下材料性质呈抛物线变化的FGM厚壁圆筒受均布荷载的解析解,并结合摩尔-库伦强度准则对冻结壁塑性状态下的应力分布进行了分析。将所得结果与均质冻结壁进行比较,总结出该类FGM冻结壁的受力特性。最后提出对冻结壁设计施工的建议。

关 键 词:功能梯度材料(FGM)  冻结壁  抛物线  解析解  摩尔-库伦强度准则

Abstract:By analytically solving this functionally graded elastic thick cylinder under uniform load,combining with the Mohr-Coulomb strength criterion,the stress distribution of the frozen wall in plastic state was obtained.The results is further compared with that from the homogeneous model to reflect some mechanical characteristics of frozen wall with FGM property.Finally,some suggestions regarding to the present design philosophy of frozen wall were proposed.
Keywords:functionally graded material(FGM)  frozen soil wall  parabolic  analytical solutions  Mohr-Coulomb strength criterion
