Effects of spatial variability of weak layer and seismic randomness on rock slope stability and reliability analysis

Soil Dynamics and Earthquake Engineering, 2021
Rock slope stability is a key research issue in geotechnical engineering. Weak layer is a distinct feature distinguishing the rock slopes from soil types, and its existence considerably controls the slope stability.

Numerical study on seismic response of a rock slope with discontinuities based on the time-frequency joint analysis method

Soil Dynamics and Earthquake Engineering, 2020
To clarify the seismic response of rock slopes, a time-frequency joint analysis method with the combined use of time, frequency and time-frequency domain analysis is proposed.

Analysis of rock slope stability under rainfall conditions considering the water-induced weakening of rock

, 2020
This study provided a feasible approach for more accurate analysis of rock slope stability under rainfall infiltration. To quantitatively analyse the influence of rainfall on slope stability, we attributed the influence of rainfall on slope stability to ...

Seismic response analysis of a bedding rock slope based on the time-frequency joint analysis method: a case study from the middle reach of the Jinsha River, China

, 2020
To investigate the seismic response of a bedding rock slope, a time-frequency joint analysis method was proposed using the finite element method (FEM) based on the time, frequency, and time-frequency domains.

Stability analysis and design charts for over-dip rock slope against bi-planar sliding

Engineering Geology, 2020
Bi-planar sliding is one of the main instabilities in over dip rock slope. The geometry and strength of the bi-planar sliding surface comprised of two sets of cross-discontinuities play an important role in slope stability assessment.

Hydromechanical Rock Slope Damage During Late Pleistocene and Holocene Glacial Cycles in an Alpine Valley

Journal of Geophysical Research: Earth Surface, 2020
Subglacial water pressures influence groundwater conditions in proximal alpine valley rock slopes, varying with glacier advance and retreat in parallel with changing ice thickness.

Dynamic response of a physical anti-dip rock slope model revealed by shaking table tests

, 2020
The anti-dip rock slopes are common geological features in Taiwan, and the failure of this type of rock slope is prone to be triggered by seismic loads. Thus, it is important to investigate its dynamic behavior for further mitigation and prevention.

A new method for constructing finite difference model of soil-rock mixture slope and its stability analysis

, 2021
A new method for constructing a digital model of soil-rock mixture is proposed in this paper. Using this method, rock blocks of arbitrary shapes can be considered and the construction of soil-rock mixtures with different block size distribution and rock ...
