This book is concerned with time-dependency in rock mechanics and rock engineering, whose spectrum is very wide. While the term “time-dependency” involves time-dependent behavior/rate-dependent behavior of rocks in a conventional sense, this books attempts to cover the spectrum as much as possible including coupled processes of thermal, hydrological and diffusions in rocks. It presents theoretical formulations, experiments, numerical formulation and examples of applications. Of paramount concern is the long-term response and stability of rock engineering structures, including for instance man-made and natural slopes and underground facilities such as tunnels and powerhouses.


"The subject of time-dependency is one of the most important and also difficult aspects of rock mechanics and rock engineering. [Additionally,] there have not been many books on the subject.

The author of this book, who is an expert on rock mechanics and rock engineering, combines his knowledge and personal experience in the field of time dependent effects on rock masses to encourage the practical use of various aspects of this subject. The book consists of detailed chapters mainly on time-dependent (rate-dependent), thermo-mechanical, thermo-hydro-diffusion and thermo-hydro-mechanical behaviours of rocks, water migration in soft rocks and its effects, hydromechanics of rocks and rock engineering structures with the presentation of experimental, numerical and empirical methods. The book also includes very useful applications and/or examples selected from the studies of the author and discussions on them.

This new book dedicated on time dependency in rock mechanics and rock engineering would be welcomed by a large group of researchers, both graduate and undergraduate students and professionals (particularly mining, civil and geological engineers and geophysicists) and also libraries. The book has also a big potential to be used as a textbook for educational purposes both in undergraduate and graduate levels and will fill the gap on this subject in literature."

Prof. Resat Ulusay, President-Elect of ISRM and Professor at the Faculty of Engineering at Hacettepe University, Turkey.

The book consists of seven detailed chapters and includes the presentation of experimental, numerical and empirical methods. In each chapter, the fundamental concepts are directly linked to applications through the presentation of a wide range of case studies. The author of this book combines his knowledge and personal experience in the field of time-dependent effects on rock masses for the practical use of various aspects of the subject. […]

This book will be useful for educational purposes as it is comprehensive and clearly written. Fundamental concepts of coupled modelling, analytical solutions and numerical implementation are presented. They are associated with experimental studies and applications to real case studies. Therefore, this book will also be useful for practitioners for the design and the long-term assessment of rock engineering structures.

Overall, the strength of the book is in a comprehensive presentation of the basic concepts, together with the reporting of main theoretical, experimental and numerical issues. Also addressed are the coupled physical processes and numerous applications to real case studies of rock engineering structures. A weakness is found in the lack of references to the existing literature, in particular on numerical modelling of coupled Thermal-Hydraulic-Chemical- Mechanical (THCM) processes.

About the Series

ISRM Book Series

The ISRM Book Series comprises significant scientific publications in rock mechanics and related disciplines. The aim of the Series is to promote the scientific output of ISRM (International Society for Rock Mechanics).

The Series will be published on a regular basis, according to the emergence of noteworthy scientific developments. Each volume in the Series is prepared independently and focuses on a topical theme. Volumes are published on an occasional basis, and include high quality scientific contributions that have not been published elsewhere before. Contributions will be rigorously peer-reviewed by experts in the field, ensuring strong scientific standards, and are expected to be leading in rock mechanics and related disciplines. The Series may include edited volumes, textbooks, reference works and books on advanced scientific topics. ISRM members benefit from a 40% discount on ISRM Book Series volume purchases.
