Establishing basement wall board finite element model, the basement outter wall and floor bottom are influenced by flexible restriction of soil.The thermal stress caused by basement outter wall and bottom board at the changing of tempreature are studied.Through the finite element analysis, the distriction situation of thermal stress at climate change process are mapped and the law of thermal stress’s change with wall length and bottom thickness is qualitatively summarized.%建立地下室墙板有限元模型,并且地下室外墙四周和底板底部受到土壤的弹性约束,研究了在气候变化下地下室外墙和底板引起的温度应力.通过有限元分析,绘制出气候变化过程中温度应力的分布情况,以及定性的总结出温度应力随墙体长度和底板厚度变化的规律.
