The load-transfer factor () in the concentric cylinder approach is often used analytical formulation axially loaded piles. a constant value (in given pile slenderness ratio and soil condition) devised under elastic ‘pre-failure’ perfect pile–soil bonding conditions (a non-slip model). Given most numerical methods have already considered slipping stage, limitations of models recently been discus...

Introduction: Embankments are constructed in many places for transportation purposes such as railways and roads. The stability of slopes embankments has always been a concern, especially cohesionless soils. There methods to increase the safety factor soil using geogrids, geocells, concrete piles, so on. conventional material used stabilize huge impact on environment. Nowadays, researchers natur...

classical soil mechanics involves the study of fully saturated soils. however, many problems encountered in geotechnical engineering practice involve unsaturated soil, in which behavior is significantly different from classical saturated soil. negative pore pressure and capillary forces develop a virtual cohesion between the grains of semi saturated soils. this kind of cohesion is dependent on ...

One of the most dramatic causes of damage of structures during earthquakes has been the development of liquefaction in saturated cohesionless deposits. These deposits have tendency to densify when subjected to earthquake loading. However, when saturated, the tendency to densify causes the excess pore water pressure to increase. This, in turn, results in the effective stress of soil to decrease....

The size of a shallow landslide is a fundamental control on both its hazard and geomorphic importance. Existing models are either unable to predict landslide size or are computationally intensive such that they cannot practically be applied across landscapes. We derive a model appropriate for natural slopes that is capable of predicting shallow landslide size but simple enough to be applied ove...
