可靠性模型块裂介质工程岩体块体理论赤平投影Based on mechanics classification of media,a reliability model for blocky engineering rockmass stability is made by mean of block theory and hemispheric projection. The stability probability of blocky surround rocks in a large underground opening is calculated ...
The results of the creep equation calculation were fitted with the experimental results with good results. The creep curve with a height ratio of 2:1 was predicted with good results. The research results provide theoretical references for long-term stability analysis of rock engineering....
According to the characteristics of fuzziness and randomness in the classification of surrounding rock stability, the cloud model is introduced to conduct the corresponding evaluation. The cloud of each factor on different stability levels is generated based on the evaluation indexes. Considering the meas...
6, when analyzing the single particle size gradations of the gangue samples under different confining pressures, it can be seen from the time-strain curves that the gangue samples with a single particle size of 20–30 mm reach the creep stability stage fastest under all four confining pressures...

Estimation of rock mass strength and deformability is important in evaluating rock mass stability of the dam site and it plays a significant role on the safe operation of the Yujian River Reservoir. In this paper, the scale effect on fracture system and mechanical properties, and Representative ...
Structural and mechanical analyses of rock masses are key components for rock slope stability assessment. The complementary use of structural analyses and discontinuum numerical modeling provides a methodology that can be applied to analyse complex 3D rock mass configurations. However, fracture persis-tenc...
While most international researchers in this area focus on understanding the geological factors that could affect the stability of the storage cavern, such as the rock salt features around the salt cavern and the geometry of the cavity (Yu et al., 2013, Mohammadi et al., 2013, Lee and Song...
According to the instability of the structural plane of the rock mass, we propose the influence of the locking segment and fracture zone on the structural plane stability and reveal the damage mechanism in the process of the progressive damage of rock structural plane under periodic dynamic perturba...
