Long-term creep of Beishan granite under uniaxial compression

open access: yesInternational Journal of Mining Science and Technology
Investigations into the long-term creep behavior of Beishan granite in uniaxial compression were conducted. Four levels of axial stress (60, 70, 87, and 95 MPa) were applied to rock specimens.

Failure characteristics of Beishan granite under unloading confining pressures

open access: yesYantu gongcheng xuebao, 2019
To better understand the effects of unloading confining pressure on failure mechanism, several trial tests on loading axial stresses and unloading confining pressures with different unloading rates are performed, and acoustic emission events are recorded

Spatial distribution of the stochastic discontinuities of Shazaoyuan granite masses in Beishan

open access: yes工程科学学报
Shazaoyuan granite masses are a substitute location for high-level radioactive waste disposal in China. The widely distributed stochastic discontinuities in the granite bodies in this area are crucial factors that control rock deformation and nuclide ...

The adsorption of Eu(III) on Beishan granite [PDF]

open access: yesSCIENTIA SINICA Chimica, 2011
The acid-base chemistry of Beishan (Gansu, China) granite (BS03, 600 m) was studied by potentiometric titration, and the adsorption of Eu(III) on the granite was investigated using a batch technique. It was found that the pHPZNPC of the granite is 9.4 at I = 0.1 M NaCl and decreases to 9.0 at I = 0.4 M NaCl. The profile of parallel titration curves

Interaction mechanism of radioactive cesium on Beishan granite [PDF]

open access: yesSCIENTIA SINICA Chimica, 2018
As an important fission product in the uranium nuclear fission, radioactive cesium (RCs) is one of the key nuclides in the high-level radioactive waste (HLW) disposal. The microscopic mechanism of interaction between Beishan granite and RCs is very essential for the performance and safety evaluation of the HLW disposal.

Acoustic Emission Characteristics and Initiation Mechanism of Instantaneous Rock Burst for Beishan Granite

open access: yesShock and Vibration
In this paper, the instantaneous rock burst test of Beishan granite is carried out by using a deep rock burst simulation test system and an acoustic emission monitoring system. The acoustic emission data were monitored in real time during the test.

Study on the mechanism of mechanical property strengthening of Beishan granite under mild temperature condition

open access: yesCase Studies in Thermal Engineering, 2022
Many researches found that mechanical properties of granite were strengthened under the mild temperature range (within 300 °C), which is positive for the long-term safety of the high-level radioactive waste (HLW) geological disposal engineering. To study
