The field of civil engineering known as geotechnical engineering studies the engineering properties of ground materials. Soil mechanics along with rock mechanics are used to the resolution of these engineering principles. Knowledge in geology, geophysics hydrology, and other relevant sciences is also helpful. Geological engineering includes the subfield of geotechnical or rock engineering. Geotechnical engineering is not only used in civil engineering but also in the military, coastal engineering, mining, petroleum and offshore construction. Geotechnical engineering as well as engineering geology share common ground in many areas of knowledge. However, engineering geology is specialty of geology, whereas geotechnical engineering is specialty of civil engineering. Soil mechanics as well as rock mechanics are similar in theory but have different principles. This geotechnical engineering book is intended for use as a reference for geotechnical engineers and other civil engineering professionals. Waste Material Usage in Geotechnical Constructions, Slope Stability, Lateral Earth Pressure, Shallow as well as Deep Foundations, Expansive Soils, Ground Improvement, Geophysics, and Environmental Geotechnology are just few of the many topics covered in this book’s chapters.
