摘　　要：对复合材料加筋壁板进行了试验和理论分析,其计算结果与试验吻合良好,在此基础上进行了线性和几何非线性对比分析,结果表明,几何非线性可提高加筋壁板刚度18.2%和强度19.1%,通过对比线性结果和几何非线性计算结果可知,结构的刚度、结构形式均会对几何非线性计算结果产生影响,在大变形工程计算中需要考虑几何非线性,以获得足够的计算精度。A test and theoretical analysis were conducted for the reinforced wall panel of composite material, the calculation result is in accordance with the test well; the comparative analysis on linearity and geometrical non-linearity was done on the basis, the result shows the geometrical non-linearity can improve rigidity and strength of reinforced wall panel. With comparison of linearity and geometrical non-linearity calculation results, it is known that the structural rigidity and form can affect geometrical non-linearity calculation result, so it needs to consider the geometrical non-linearity in the calculation of big deformation project to obtain sufficient calculation accuracy.
