GIT | CIVIL | ENGINEERING GEOLOGY LABORATORY (CEC304)

Rationale

Geology is the study of earth, the minerals and rocks of which it is made. The study of the structures presents in the rocks and the effects of the natural forces acting upon them are essential to understand by civil engineers because all work performed by them involves the earth and its features. The study helps to understand the causes and prevention of many geological activities like earthquakes, landslides and volcanoes. For a civil engineering project like dams, bridges, buildings, etc. to be successful the engineers must understand the foundation rock and their structures, it also helps them to examine rocks for important metals, oil, natural gas and groundwater.

Introduction

Engineering Geology lab is equipped with around 400 specimens of minerals and rocks. The large quantity and variety of specimen enables students to understand various processes of their formation, characteristics and their importance in civil engineering. There are about 150 Samples of Minerals, 150 Samples of Rocks, various sets of minerals based on physical properties, Hardness box and Structural models for effective understanding of geological structures. The collection includes some of the rare samples like petrified wood, Corals, rock samples from all over India.

Outcome

Learner will be able to...
- Identify various rock forming minerals on the basis of physical properties.
- Explain the characteristics of Igneous, Sedimentary and Metamorphic rocks and assess their suitability as construction material and foundation rock.
- Interpret the rock characteristics and comment on their suitability as water bearing horizons.
- Interpret the geological map and assess the suitability of the site for Civil Engineering works.
- Solve the borehole problems and interpret it in order to understand subsurface Geology of the area.
- Calculate RQD and evaluate the rock masses for Civil Engineering Works.
