CE 363 SOIL MECHANICS CHAPTER 1: INTRODUCTION METU Civil Engineering Department Geotechnical Engineering Division Geotechnics and Engineering Design Geotechnics: •The branch of civil engineering concerned with the study and modification of soil and rocks. •The main concern is the application of scientific and engineering principles to the solution of civil engineering and other problems created by the nature and constitution of the Earth's crust. Engineering Design: •The process of devising a system, component, or process to meet desired needs. •It is a decision-making process (often iterative), in which the basic science and mathematics and engineering sciences are applied to convert resources optimally to meet a stated objective. 2 METU Civil Engineering Department Geotechnical Engineering Division METU Civil Engineering Department Geotechnical Engineering Division METU Civil Engineering Department Geotechnical Engineering Division Welcome to World’s Sub-Surface You never see our best work because it is buried right under your feet!
