将瓦楞纸板等效为正交各向异性板结构，采用实验法和有限元法对瓦楞纸箱在4种环境湿度下的抗压强度进行了研究，获得了其在各环境湿度下的载荷一变形曲线和抗压强度值。瓦楞纸箱抗压强度随相对湿度的增高呈指数规律下降，这表明环境湿度对纸箱抗压强度的影响极为显著。有限元分析结果与实验结果一致，表明采用正交各向异性板结构有限元模型可有效分析瓦楞纸箱的变形和抗压强度。
將瓦楞紙闆等效為正交各嚮異性闆結構，採用實驗法和有限元法對瓦楞紙箱在4種環境濕度下的抗壓彊度進行瞭研究，穫得瞭其在各環境濕度下的載荷一變形麯線和抗壓彊度值。瓦楞紙箱抗壓彊度隨相對濕度的增高呈指數規律下降，這錶明環境濕度對紙箱抗壓彊度的影響極為顯著。有限元分析結果與實驗結果一緻，錶明採用正交各嚮異性闆結構有限元模型可有效分析瓦楞紙箱的變形和抗壓彊度。

The compression strength of corrugated box under different humidity is investigated by experiments and finite element method with an orthotropic plate theory, and the load-deformation curve and compression strength of corrugated box are obtained. The compression strength of corrugated box is exponentially decreased with the increasing of the relative humidity. The results from finite element method are consistent with the experiments, and the finite element method with orthotropic plate theory can be effectively used to analyze the deformation and compression strength of corrugated box.
