The emergency control of nuclear contaminated water leakage using artificial ground freezing (AGF) method has good application prospects, but the actual blocking effect is not ideal at present. To promote the solution of this problem, this paper designed a test system for evaluating the impermeability of freezing method, and it conducted blocking s...
Under the influence of seepage erosion and nuclide decay heat release, the frozen soil wall constructed by artificial ground freezing method (AGF) to prevent nuclear leakage is prone to occur local ablation and impermeability failure. To ensure its long-term safety and effectiveness, this study conducted a series of laboratory tests to assess the b...
The level of nuclear waste emergency disposal has become an important factor restricting the rapid development of the nuclear energy industry in the global energy revolution. To promote the effective application of artificial ground freezing (AGF) for the treatment of nuclear wastewater leakage, the mass transfer and migration mechanism of key nucl...
The mesoscale effect of climate change and engineering activities on a superficial frozen soil–rock mixture (FSRM) in regions is complex. The decrease in strength caused by particle ice film ablation under temperature rise has various effects, such as upper subgrade settlement deformation. However, the internal mechanism of FSRM strength degradatio...

The growth and melting of internal ice crystals reorganizing the pore structure and internal skeleton of soil-rock mixture (S-RM), which leads to the deterioration of the S-RM shear strength after freeze–thaw cycles and its strength characteristics after the cycles are different from the normal temperature one. Due to unclear S-RM strength deterior...

Soil–rock mixtures (S-RMs) are widely distributed in the shallow surfaces of cold regions that experience frequent freeze–thaw cycles, considerably threatening the stability of the soil–rock slopes on both sides of the road. We examine the S-RM shear strength and deformation characteristics under different freeze–thaw cycles through experiment and...
