SF4002 Geology for Geotechnical Applications Syllabus:
SF4002 Geology for Geotechnical Applications Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To impart knowledge and skills in assessing the quality of foundation rocks, their aggregates and building materials derived from rocks and assess the geological suitability of sites for engineering projects.
UNIT I ENGINEERING PROPERTIES OF ROCKS AND MINERALS
Geology for foundation engineering – Types of rocks, rock description-texture, structure, composition and its relation to quality and strength of rocks, engineering classification of rocks –weathering grade and its significance in engineering site-Engineering properties of rocks – Physical and chemical properties of minerals and their relation to strength and durability of rock.
UNIT II SURFACE AND SUBSURFACE GEOLOGICAL INVESTIGATIONS
Surface investigations: Bed rock attitudes – Strike and dip of rocks-Field mapping- thickness, calculation of True thickness and vertical thickness of bed rock-pitting and trenching-Subsurface investigations: electrical and seismic geophysical methods in subsurface geological investigations for foundation engineering, applications of GPR in subsurface strata studies.
UNIT III LOGGING AND CORE SAMPLING TECHNIQUES
Core logging techniques – Resistivity log, Neutron log, Sonic log, Gamma log etc. Bore logging methods, interpretation. Drilled core sections – rocks and soil sampling methods. Description of discontinuities-Fence diagrams, RQD and RMR.
UNIT IV CLAY MINERALS IN GEOTECHNICAL INVESTIGATIONS
Physical, chemical and thermal properties of clays-identification-effects of clay minerals classification and types of clays- plasticity, clay behaviour under natural and hydrated conditions.
UNIT V GEOLOGICAL INVESTIGATIONS FOR FOUNDATION SITES
Ground stability studies – Scour and erosion studies-stability of slopes: Geological information for slope stabilization and geological solution for slope stability in landslides areas-Overview of rocks of TamilNadu.
OUTCOMES:
On completion of the course, the student is expected to be able to;
CO1 Identify various rock types and understand the strength and durability of different rock types.
CO2 Map the surface and subsurface geological formations using geological and geophysical exploration techniques.
CO3 Explore and analyse the subsurface rocks and their discontinuities for design and construction of major Civil engineering structures.
CO4 Understand the geological characteristics of clay minerals and their effect
CO5 in choosing suitable sites for foundations. Analyse the slopes and decide the suitable methods for improving slope stability and manage unstable slopes efficiently.
