The freeze-thaw weakening of rock structural planes on slope stability: effects of cycle numbers and burial depth

Geomatics, Natural Hazards & Risk
This study investigates rock slopes in cold-region open-pit mines through integrated laboratory experiments and numerical simulations, revealing the freeze‒thaw weakening laws of structural planes and fractured rock masses.

Stability Assessment of High and Steep Cutting Rock Slopes with the SSPC Method

Advances in Civil Engineering, 2021
The stability of high rock slopes has become a key engineering geological problem in the construction of important projects in mountainous areas. The original slope stability probability classification (SSPC) system, presented by Hack, has made obvious ...

Stability Analysis of the Soil-rock-mixture Slopes Under Different Rock Block Proportions and Dip Angles of Bedrock

工程科学与技术, 2019
In order to accurately analyze the stability of soil-rock-mixture slopes, a method which considers the random distribution, proportion of rock blocks, and the dip angles of bedrock is put forward.

Overhanging rock slope by design: An integrated approach using rock mass strength characterisation, large-scale numerical modelling and limit equilibrium methods

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Overhanging rock slopes (steeper than 90°) are typically avoided in rock engineering design, particularly where the scale of the slope exceeds the scale of fracturing present in the rock mass.

Stability Prediction of Residual Soil and Rock Slope Using Artificial Neural Network

Advances in Civil Engineering, 2022
A sudden downward movement of the geomaterial, either composed of soil, rock, or a mixture of both, along the mountain slopes due to various natural or anthropogenic factors is known as a landslide.

An Energy-Based Discrete Element Modeling Method Coupled with Time-Series Analysis for Investigating Deformations and Failures of Jointed Rock Slopes

Applied Sciences, 2021
The discrete element method (DEM) can be effectively used in investigations of the deformations and failures of jointed rock slopes. However, when to appropriately terminate the DEM iterative process is not clear.

Microseismic monitoring and numerical simulation on the stability of high-steep rock slopes in hydropower engineering

Journal of Rock Mechanics and Geotechnical Engineering, 2015
For high-steep slopes in hydropower engineering, damage can be induced or accumulated due to a series of human or natural activities, including excavation, dam construction, earthquake, rainstorm, rapid rise or drop of water level in the service lifetime

Rock glaciers in Daxue Shan, south-eastern Tibetan Plateau: an inventory, their distribution, and their environmental controls [PDF]

The Cryosphere, 2018
Rock glaciers are typical periglacial landforms. They can indicate the existence of permafrost, and can also shed light on the regional geomorphological and climatic conditions under which they may have developed.
