Abstract We conducted field observations and experiments to explore debris flow dynamics, sediment transportation slope erosion at an active natural gully in the headwaters of Jiangjia Ravine (Dongchuan region, Southwest China). In this hillslopes were heavily jointed, weathered sparsely vegetated, providing continuous rich supplies for initiating flows. The propagated channel as a sequence sur...

Most empirical and numerical approaches to design in rock mechanics incorporate rock mass classification. Numerical design methods generally use classification values to calculate input parameters for stress-based failure criteria. Empirical methods use classification to allow comparisons between similar rock mass conditions, generally based on a graphical design technique that differentiates s...

in this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (ucs), easy casting, high flexibility, instant hardening, low cost and easy availability. the main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. the effect of four parameters such as joint roughness coefficient (jrc), bridge length (l), b...

Abstract. Landslides are a major geohazard that cause thousands of fatalities every year. Despite their importance, identifying unstable slopes and forecasting collapses remains challenge. In this study, we use the 7 February 2021 Chamoli rock–ice avalanche as data-rich example to investigate potential remotely sensed datasets for assessment slope stability. We imagery over 3 decades preceding ...

It is well known that joints or fissures have an important effect on the failure mechanism of natural rocks. Previously, many numerical and experimental papers been carried out to study strength anisotropy characteristics jointed However, few studies nonpersistent rock masses with different persistence, especially for in three dimensions. In present study, a 3D mass inclinations (θ) persistence...

The explosion process of explosives in a borehole applies a very high pressure on its surrounding rock media. This process can initiate and propagate rock fractures, and finally, may result in the rock fragmentation. Rock fragmentation is mainly caused by the propagation of inherent pre-existing fractures of the rock mass and also from the extension of the newly formed cracks within the intact ...
