【摘要】 本文根据国内外冻土实验成果,对非均质弹性冻结壁应力的计算作了初步探讨。并用有限差分法求解冻结壁的应力,获得了冻结壁内各应力分量的分布曲线,较均质弹性假设的计算更能反映冻结壁的实际应力状态,对冻结壁不均质性的研究有参考意义。更多还原

【Abstract】 In this paper, the calculating method of stresses in frozen wall treated as a nonhomogeneous elastic medium is discussed, based on the results of domestic and overseas investigations. The finite difference method is applied in calculating the three-dimensional stresses in frozen wall and the stress distribution curves have been plotted. The authors point out that the results are more closely to the actual stress distribution in comparison with the results obtained by the calculating method which treats the frozen wall as a homogeneous medium.更多还原
