摘要
基于不同模量理论,讨论了复杂应力状态下不同模量挡土墙结构的中性层,推导了同时考虑x、y方向应力情况下该结构的中性轴及正应力、剪应力的解析解.并编制相应的有限元程序进行计算,将其数值解与解析解进行误差对比.最后对不同模量计算结果与经典力学同模量计算结果进行了分析对比.基于两种理论计算结果的差异,提出了对该类结构计算的合理建议.
According to the elastic theory of different modulus, the neutral layer of retaining wall under complex stress was discussed. Taking into account the stress of axis x and y simultaneously, the formulas for neutral axis, normal stress, shear stress were derived. The finite element program was compiled for calculation, and the comparison between the results of the finite element program and the one of the formulas was also made. Finally, the results of different modulus and the classic theory of same modulus were compared and analyzed, Based on the difference of the results of two theories, a reasonable method for the calculation of this structure was proposed.
