本文为了探讨在砂土层中盾尾空隙对地层移动的影响,进行了模型实验,通过实验获得了不同盾尾空隙对地层移动的影响,用回归分析拟合了有关地层沉陷曲线,为了获得砂土层中的内部移动形态,采用了近景摄影这一新方法,最后用邓—肯(Dvcan J·M)模型的有限元方法对实验结果进行了比较。
In order to investigate the influence of shield-tail void on formation movement in sandy soil, a model experiment was carried out. The influence of different shield-tail voids on formation movement was obtained by experiments. Regression analysis was used to fit the curve of formation subsidence. The internal movement patterns in the soil layer were modeled using near-field photography. Finally, the experimental results were compared with the finite element method of the Dvcan JM model.
