Improved geotechnical properties in salt-treated highly sensitive landslide-prone clays

A New Landslide Inclinometer Using Highly Sensitive Gauges

The paper presents a device devoted to detect and measure earth displacements produced by landslides. It is part of inclinometer type geotechnical instruments and is based on measuring the deformation produced to a rod vertically mounted into the ground during soil layers sliding. With respect to other commercial devices, our inclinometer is characterized by high sensitivity to very small defor...

Addressing the Geotechnical Challenges Posed by Soft Clays

Geotechnical Properties of Mine Fill

Mine fill is the material placed underground to fill the voids created by mining excavations. It provides overall large scale ground stabilization while allowing localized pillar recovery. In addition to providing a working floor or back, mine fill has the potential to reduce subsidence and minimize dilution. Mine fill is essential to cut and fill, benching and sublevel stoping mining methods. ...

Temperature Effects on Geotechnical and Hydraulic Properties of Bentonite Hydrated with Inorganic Salt Solutions

This study investigated the combined effect of temperature and single-species salt solutions on geotechnical properties (swell index and liquid limit) and hydraulic conductivity of bentonite applying different cation types, concentrations, and temperatures. Results showed that both the swell index and the liquid limit decreased with an increase in salt concentration irrespective of the type of ...

GIS-based route planning in landslide-prone areas

Many parts of the world with young mountain chains, such as the Himalayas, are highly susceptible to landslides. Due to general ruggedness and steep slopes, roads provide the only way of transportation and connectivity in such terrains. Generally, landslide hazards are overlooked during route planning. In this study, in a test area in the Himalayas, various thematic layers, viz. landslide distr...
