About
Rock slope engineering demonstrates a crucial responsibility in confirming the stability and safety of natural and technogenic slopes. This facet is fundamental cum applied attempt in translating different information related to geo-ground encountered in natural slopes or slopes formed during and after developments of varieties of engineering structures for safe, healthy and prosperous progress of civilization. The instabilities of such slopes are detrimental to live and properties of peoples, disturbances in existing ecosystem and deterioration in environment. Thus, to ensure the sound, safe, stable, naturally compact, environmentally sustainable and economically feasible development of various facilities concern to extraction of natural resources, proper settlements, stable protective structures, clean and healthy environment are only possible after proper understanding of numerous facets related to slope instabilities, their evaluations, and mitigations for stabilization of sloppy geoground. This course is widely intended to cover major aspects of rock slopes categorization, characterization, evaluations and mitigations in techno-economical extraction of natural resources, construction of infrastructures, and protective structures under various natural and anthropogenic forces in environmentally sustainable manner. Thus, this course will assists students, scientists, policy makers and professional concern to examine the behaviour and responses of geoground for understanding and solving numerous instabilities related technical issues arises during creation of various facilities for safety and welfare of society and nation. The present course is equally relevant to consultants, engineers, experts, bureaucrats and policy makers dealing with such sloppy geoground.
Intended audience: Graduate, Post-graduate and Ph.D. students of Earth sciences, Civil Engineering, Mining Engineering, Petroleum Engineering, Geophysics, Environmental Science and Engineering and…
