摘要
For deep overburden embankment base, erosion-type internal tube surge is a key problem affecting the stable operation of dams. To study the fine view mechanism of erosion type tube surge in deep overburden, this paper integrates transparent soil technology, planar laser-induced fluorescence imaging technology, firstly, through self-developed transparent soil and visualization model test platform, carry out saturated transparent soil test research, so as to obtain the two-dimensional slice collection of transparent soil samples; then with the help of Avzio software to its three-dimensional reconstruction, split solid particles and pore liquid, the pore network model is generated in the three-dimensional model with Avzio software to obtain the pore-related parameters and throat-related parameters, and plot the pore equivalent diameter and throat diameter distribution; finally, the critical fine particle diameter distribution curve is predicted by combining the previous statistical throat diameter distribution curve, and then the internal stability of the soil is evaluated, and the accurate throat distribution curve obtained predicts the fine particle diameter distribution curve. The method is proposed to evaluate the internal stability of soil by predicting the fine particle size distribution curve from the obtained accurate throat distribution curve.
