This study investigates the effectiveness of vegetation reinforcement on stability a slope with red-bed soft rock in along Xining-Chengdu railway, China. Four kinds were considered to reinforce soil and slope. The rooted parameters determined based laboratory tests. A numerical model was developed actual geometry layer distributions. soils modeled as elastic perfectly plastic materials represen...

Trentepohlia is a genus of subaerial green algae which is widespread in tropical, subtropical, and also temperate regions with humid climates. For many years, small-scale Trentepohlia coverage had been found on the rocks of some glacier valleys on the northern slopes of Mt. Gongga, China. However, since 2005, in the Yajiageng river valley, most of the rocks are covered with deep red coloured al...

Terrestrial laser scanning (TLS) technology has recently increased its interest in the geological community for the geometric survey of slopes involved in landslides and for the acquisition of a DSM of rock wall, that can be used for predicting possible paths of falling dawn stones. In particular, the paper deals with this last application, focusing on some open aspects which have devised to be...

A landslide hazard zonation is a division of the land surface into areas, and the relative ranking of these areas according to degrees of actual or potential hazard from landslides on slopes. Zonation from scientific research does not generally imply legal restrictions, but can be useful to those people who are charged with the land management, by providing them with information that is indispe...

Unmanned planetary landers to date have landed "blind"; that is, without the benefit of onboard landing hazard detection and avoidance systems. This constrains landing site selection to very benign terrain, which in turn constrains the scientific agenda of missions. The state of the art Entry, Descent, and Landing (EDL) technology can land a spacecraft on Mars somewhere within a 20-100km landin...

Rayleigh distillation models are developed to describe theoretical growth zoning of Lu, Hf, Rb, Sr, Sm, and Nd in typical garnet crystals from metapelites and metabasites. Effects of diffusion-limited transport within the matrix and intracrystalline diffusion are also considered qualitatively. Theoretical zoning profiles show strong depletions of Lu in garnet rims compared to cores, but virtual...

Soil-rock mixtures (S-RMs), as special engineering geological materials, are widely distributed in mountainous regions and important hosts of slope disasters. Stability studies very for predicting S-RM safety during the construction operation projects. To investigate stability considering spatial distribution oversized rock blocks slope, distinct element method (DEM) program particle flow code ...
