In the heart of big cities, a less obvious challenge exists right under our feet. The everyday activities of city life, like traffic, construction, and industrial work, do more than just create noise. They send vibrations through the ground, which can be problematic, sometimes even destabilizing buildings and affecting the people who live there. This modern issue needs a modern solution. This book introduces the concept of trenches filled with a material called geofoam, an innovative method to control these ground vibrations. Mehran Naghizadeh delves into a detailed study to see how placing these trenches in specific locations can help protect against these vibrations. The book walks through various automated 2D and 3D models, demonstrating how the trenches can be effectively used to protect areas close to and far from the source of vibrations. The study goes beyond just explaining what these trenches are and how they work. It looks into the reasons behind their design, examining different trench shapes and how each shape helps in managing these underground vibrations. The challenge is more complex than it seems. The ground we walk on is not just a single layer but has different layers with various properties. This book takes you on a journey to understand how these layers influence the effectiveness of our vibration warriors. It’s an exploration of how every layer in the soil contributes to managing vibrations. About the author Dr. -Ing. Mehran Naghizadeh is a project manager specialized in digitalization and BIM within the field of geotechnical engineering. .

The purpose of writing this book is to provide the latest research findings in ground control techniques in mining engineering, especially the rock bolting techniques. Since rock bolts are widely used in mining engineering and civil engineering, they are significant in guaranteeing the safety of underground openings. However, instability issues still occur with the rock bolting technique. Therefore, it is valuable to understand the exact load transfer mechanism of rock bolts. This book summarised the recent research work regarding rock bolting conducted by the authors. It is valuable for the readers to fully understand the reinforcing mechanism of fully grouted rock bolts. This book focuses on the bond failure mode of fully grouted rock bolts, which is the most widely encountered failure mode in rock bolting. Different investigation approaches are used in this book, including numerical simulation, analytical modelling and experimental tests. Therefore, this book conducts a comprehensive study to reveal the bond failure process of fully grouted rock bolts. Moreover, it reveals the corresponding bond failure mechanism. Therefore, it helps the reads to fully understand the bond failure mechanism of rock bolting. Moreover, it helps the readers to develop new approaches and methods to prevent failure of the rock bolting system. This is an open access book.

This book focuses on the unified solutions and analysis for the problems in soil mechanics based on the unified strength theory, which is a new theory on the yield and failure of materials under multi-axial stresses. Then, it provides a system of yield and failure criteria adopted for most materials, from metallic materials to rocks, concretes, soils, polymers, etc. It includes the Tresca criterion, Mohr–Coulomb theory, and Mises criterion as well, which are special cases or linear approximation of the UST. .
