Shear Strength Behavior of Different Soils
Abstract: The magnitude of shear strength of soils plays a major role in determining bearing capacity of shallow footings, frictional resistance for piles, stability of slopes, etc. for the safe and economic design of civil engineering structures. Based on the ideas of different researchers, shear strength of clay can be improved either by mixing sand or gravel, silty sand with gravel, and sand either with silt or gravel or granulated blast …

DEM Simulation of Macro and Micro-Scale Behavior of Granular Materials during Loading and Unloading
Abstract: The present paper aims at comparing the simulated stress-strain behavior of granular materials quantitatively with the experiment and exploring the evolution of the micro-scale behaviors during loading and unloading using the discrete element method (DEM). A numerical sample consisting of 9826 randomly generated spheres similar to the experiment was prepared. The numerically prepared isotropic sample was subjected to loading and unloading under strain controlled condition. It is noticed that the …

ENHANCED TECHNIQUE FOR HYDRAULIC FRACTURING PROCEDURE IN FRACTURED ROCK MASS
Abstract: Notwithstanding the broad hypothetical work about hydraulic fracturing technique for estimation of stresses in rock mass, the experimental work has so far been restricted, particularly on account of its legitimacy in fractured rocks. Much work has been completed about the induced fractures created by hydraulic fracturing tests, however not on the impact of previously existing fractures and joints and their impact. When a fracture has been originated at the borehole …

Evaluate Variations of Deflections of Fixed Headed Pile from Non-Linear Load - Deflection Curve under Lateral Loading
Abstract: Lateral stability is the vital issue when the pile stands in several soft clay either sand layers. In reality, structure and soil both are show non-linear behaviors. Proper evaluation of non-linear behavior has not so essay in theory. However, slight non-linear effects are included in pile deflection from load-deflection curve of pressuremeter test in laboratory. Pressuremeter modulus is influenced deflection of fixed headed piles. Predicting the variations of non-linear load …

Negative skin friction and Neutral plan on the pile in collapsible soil:A Review Study
Abstract: The use of the pile in geotechnical engineering has become interesting due to the many challenges facing the installation process and the problems that may occur suddenly during construction if it is not taken into account. construction of piles in collapsing soil such as soft soil or gypsum soil leads to losses in the bearing capacity of the pile by creating an imaginary additional loading that is above the pile …
