The self-sealing and self-healing behaviors of technological gaps in a high-level radioactive waste repository are analyzed. The systematical findings are summarized based on the previous studies on the effects of techno...

Based on the experimental results and previous studies, the stress ratio at the failure (Mf) under different confining pressures is modified, and the pressure dependency of plastic modulus is discussed. Considering the i...

According to the fractal theory, the fractal distribution formula of gradation for rockfill materials is deduced. The field gradation data of six dams with clay core and five 200 m-high CFRDs are used to verify the relev...

Considering the nonlinear characteristics of dilatancy and strength of coarse-grained materials, an elastoplastic constitutive model based on microstructures is established within the framework of classic elastoplastic t...

The safety of core wall type rockfill dams during reservoir impounding is greatly affected by the slaking deformation of upstream shell materials. The slaking deformation of the rockfill materials is analyzed using the t...

The mathematical methods of FFT and wavelet transform are used to deal with the acoustic emission (AE) frequency information of rock fracture firstly. Combined with the spectral distribution of AE signal, the main respon...

Pore structure is the index reflecting the nature of the physical and mechanical properties of the soil. The resolution scale of the traditional medical CT is not high enough to identify the single grain or pore characte...

Considering the heterogeneity characteristics of concrete materials, the method of the mesoscopic mechanics is used to investigate the dynamic damage of slabs of concrete face rockfill dam (CFRD) combined with the statis...

In the DEM simulation of mechanical response of methane hydrate or weathered rock, the real shape and size of inter-particle bond significantly affect the macro-mechanical properties of the materials, therefore it is nec...

The design criteria of Terzaghi filter layer have laid the foundation for the researches on filter layers, which are safet enough for uniform cohesionless soil, but not secure for uneven cohesionless soil, and they are n...

The electrical resistivity method is the main non-destructive method for measuring compaction and moisture migration of the unsaturated soils. The van der Pauw method is a well established technique for measuring the res...
