Book Description
In this study is an attempt was made to improve our understanding of rock cutting process by hard rock Tunnel Boring Machines (TBM) and evaluate the impacts of rock mass properties on machine performance. To achieve these objectives, an extensive database on filed observations of TBM performance in various projects and rock mass conditions data has been established. This database includes the data from 10 different job sites with more 60 km of total length of bored tunnels. A set of new empirical performance prediction models have been developed with reasonably high degree of correlations by performing a series of multiple regression analysis. Also a new Rock Mass Adjustment factors for Colorado School of Mines (CSM) prognosis model has been de-rived from the statistical analysis. The accuracy of developed models and adjustment factors has been verified by comparing the observed data with estimations provided by NTNU and CSM models. A very close agreement has been obtained.

Book Description
This book covers the tunnel boring machine (TBM) performance classifications, empirical models, statistical and intelligent-based techniques which have been applied and introduced by the researchers in this field. In addition, a critical review of the available TBM performance predictive models will be discussed in details. Then, this book introduces several predictive models i.e., statistical and intelligent techniques which are applicable, powerful and easy to implement, in estimating TBM performance parameters. The introduced models are accurate enough and they can be used for prediction of TBM performance in practice before designing TBMs.

Book Description
A key factor in successful application of Tunnel Boring Machines (TBMs) technology in tunneling is the ability to develop accurate performance estimates for determining project schedule and costs. Over many years of TBM related research, the Earth Mechanics Institute of the Colorado School of Mines (CSM) has developed a computer based model to predict the performance of TBM in hard rock. Although the CSM model has proven reliable in massive rock conditions, its accuracy has been limited in rock mass exhibiting a high degree of fracturing. Quantifying the rock mass fracture and intact rock brittleness effects into the CSM model, Modified CSM Model has been developed. This book named as "Modified CSM Model for Predicting TBM Performance in Rock Mass" is related to rock mass-TBM interaction. The book reviews the well-known TBM performance prediction models such as; Norwegian University of Science and Technology (NTNU), QTBM, CSM, and Modified CSM. Further, it includes geotechnical and technological information related to the projects used for development of the Modified CSM model. The book is useful for engineers and scientists who deal with rock mechanics and TBM tunneling.

Book Description
Engineering technology is of crucial importance to the infrastructure on which modern societies depend, and keeping abreast of the latest research and developments in the field is of vital importance. This book presents the proceedings of HCET 2022, the 7th International Technical Conference on Frontiers of Hydraulic and Civil Engineering Technology, originally due to be held, in Sanya, China, from 25-27 September 2022, but instead held as a fully virtual event on Zoom due to continued uncertainty related to the Covid 19 pandemic. HCET is a platform for the dissemination of research results on the latest advances in the areas of hydraulic and civil engineering technology and environmental engineering, and provides an opportunity for scientists, researchers and engineers from around the world to exchange their findings, discuss developments, and possibly establish a basis for collaboration. A total of 275 submissions were received from international contributors, and all were subjected to a rigorous peer-review process, with each paper reviewed by a minimum of two experts. Papers were also checked for quality and plagiarism, after which, 163 papers were accepted for presentation and publication. Topics covered include the research and development of concrete structure design and analysis, structural mechanics and structural engineering, geological exploration and earthquake engineering, building technology, urban planning, energy, environment and advanced engineering science and applications. The book offers a state-of-the-art overview of recent developments, and will be of interest to all those working in the fields of hydraulic and civil engineering technology.
