This publication includes 82 technical papers presented at Rocscience International Conference (RIC) 2021, held online on April 20 and 21, 2021. Rocscience created this event to bring geotechnical academics, researchers and practitioners together to exchange ideas as part of celebrating 25 years of the company's existence. The papers in these proceedings were from keynotes, panel discussions and papers, selected after careful review of over 100 technical submissions delivered at RIC 2021. The technical papers were grouped into sessions based on their subject areas. The conference aimed to stimulate discussions that could help the industry work towards overcoming geotechnical engineering limitations today. It also sought to foster creative thinking that will advance the current states of the art and practice. The keynote addresses, panel discussions and technical presentations tried to examine geotechnical problems and situations from fresh perspectives. RIC 2021 hopes that the proceedings will continue to enrich our thinking and contribute to achieving a critical mass of change in our practices and approaches. We look forward to significant improvements in our industry.

Rock salt formations have long been recognized as a valuable resource - not only for salt mining but for construction of oil and gas storage caverns and for isolation of radioactive and other hazardous wastes. Current interest is fast expanding towards construction and re-use of solution-mined caverns for storage of renewable energy in the form of hydrogen, compressed air and other gases. Evaluating the long term performance and safety of such systems demands an understanding of the coupled mechanical behavior and transport properties of salt. This volume presents a collection of 60 research papers defining the state-of-the-art in the field. Topics range from fundamental work on deformation mechanisms and damage of rock salt to compaction of engineered salt backfill. The latest constitutive models are applied in computational studies addressing the evolution and integrity of storage caverns, repositories, salt mines and entire salt formations, while field studies document ground truth at multiple scales. The volume is structured into seven themes: Microphysical processes and creep models Laboratory testing Geological isolation systems and geotechnical barriers Analytical and numerical modelling Monitoring and site-specific studies Cavern and borehole abandonment and integrity Energy storage in salt caverns The Mechanical Behavior of Salt X will appeal to graduate students, academics, engineers and professionals working in the fields of salt mechanics, salt mining and geological storage of energy and wastes, but also to researchers in rock physics in general.

This book extensively covers rock mechanics and engineering, playing a vital role in mining, geological, and civil applications. It explores the stability, failure, and behavior of rock masses, offering control and prediction methods. Fundamental concepts, stress and strain analyses, failure theories, and rock characteristics are addressed, essential for safety in mining and construction. Applications like geological hazard assessment, slope stability, and foundation design demonstrate its significance in civil and geological engineering. The book's structured approach includes an overview in Chapter 1, stress analyses in Chapter 2, and plane strain analyses in Chapter 3. Subsequent chapters delve into rock behavior, failure theories, and specific properties. Practical aspects, such as designing underground openings, are covered in later chapters. The incorporation of numerous solved tutorials enhances its value for students and educators seeking a comprehensive understanding of these pivotal topics.

The main topic of this book is the calculation of underground structures at the limit states of serviceability. It considers the main schemes typical for underground structures for various purposes, gives the corresponding mathematical models describing the main geo-mechanical and technological factors in the construction and operation of extended excavations. Generalized criteria are proposed for making a technically and economically justified solution of the problem of determining the optimal forms and sizes of workings, bearing capacity, type of support and its erection, depending on the structural features of the rock mass, the primary stress fields of gravitational, tectonic, seismic acting in it. and technological origins, operational requirements for extended excavations. The corresponding algorithms, block diagrams and specific numerical examples of calculations are given. In most of the existing calculation methods the structure is considered in the elastic stage, the strength limit of the bearing capacity is considered as the moment when the maximum internal stresses reach the corresponding design resistances of the material. If it is legitimate to use this criterion in certain cases of calculation of statically determinable structures operating in the given loading mode, then in cases where the support operates in the mode of mutually influencing deformation together with the rock mass, it leads to a significant waste of material. In addition, this book: Describes contemporary methods for calculating the limit states of underground structures Covers a wide range of mining and geomechanical conditions and loading modes of underground structures Considers various schemes of ground-structure and modes of failure for different kinds of structures.

This open access book presents work collected through the Liquefaction Experiments and Analysis Projects (LEAP) in 2019 (LEAP-ASIA-2019) following the LEAP-UCD-2017 whose results have been published as a first volume. In addition to the research targets set in the previous one, such as the repeatability, variability, and sensitivity of lateral spreading on mildly sloping liquefiable sand, this volume includes research efforts to validate the generalized scaling law (hereafter “GSL”) for the identical prototype with the one employed in UCD-2017. In LEAP-ASIA-2019, 10 institutes around the world conducted 23 tests in total. It was the first multi-institutional attempts to investigate the validity of the generalized scaling law for the saturated sandy sloping deposit with wide range of initial conditions. The experimental data provided a unique basis for assessing the capabilities of six different simulation platforms for numerical simulation of soil liquefaction. The results of the experiments and the numerical simulations are presented and discussed in papers submitted by the project participants.
