This book systematically illustrates the dynamic mechanical behaviors and discusses the fundamentals of the constitutive modeling of roller-compacted concrete (RCC), influenced by the construction technique and mix design. Four typical problems are analyzed using laboratory tests, numerical simulation and theoretical analysis, i.e., to illustrate the special dynamic mechanical behaviors of RCC, to reveal the dynamic size-dependence of mechanical properties, to discuss the aggregate size effect on dynamic mechanical properties, and to modify the dynamic constitutive model for RCC. Generally, the constitutive modeling of RCC needs a comprehensive understanding of dynamic size-dependence and aggregate size effect of concrete that coupled with the strain-rate sensitivity. So that, readers can master the modified dynamic constitutive model of RCC to analyze and solve the problems in blast-resistance analysis and protective design of RCC dams.This book can be used as a postgraduatetextbook for civil and hydraulic engineering in colleges and universities, and as an elective course for senior undergraduates. It can also be used as a reference for relevant professional scientific researchers and engineers in field of protective design of concrete structures.

The book is based on stochastic theory of sediment motion, particularly the theory of transition intensities. It provides a complete theory and equation system of non-equilibrium transport of non-uniform suspended load. The content proposed theory reports, for the first time in literature, the general boundary condition of diffusion equations of non-equilibrium transport with transition intensities. The book also introduces the theoretical expressions of size distribution of the carrying sediment capacity, efficient bed material grade, and saturation recovery coefficient This book describes the application of non-equilibrium transport theory and provides solutions to some long-standing unsolved controversial problems related to sediment transport. It establishes a generic mathematic model of reservoir sedimentation and river channel evolution; illustrates the same transport regulars of wash load and bed material load; demonstrates the multi-valued nature of carrying-sediment capacity and its single-valued consideration; and describes the mechanism of bed material coarsening. This book is of interest to a wide audience including students, technicians, and academics, primarily working in the field of river hydra-dynamics. In addition, this book receives attention from the research community working in fields, such as hydrogeology, hydraulic engineering, river navigation, wastewater treatment, and environmental protection

Practice has proven that conducting safety evaluations of reservoir dams has become a necessary measure to ensure the safety of water conservancy projects. This book introduces the development and achievements in the safety management of reservoir dams in China. Each chapter systematically sorts out and integrates evaluation measures related to different stages of the entire life cycle of reservoir dams, including planning, design, construction, operation and maintenance, repair and reinforcement, and decommissioning or removal, forming a complete dam safety evaluation management system.This book emphasizes the importance of conducting on-site inspections for dam safety management. A differentiated safety evaluation method and disposal strategy have been proposed for different engineering scales, management levels, and risk levels, making the technical route of safety evaluation more reasonable and operable. The book is written as a reference book for professional engineers and is also suitable for post graduate courses.

This open access book provides a complete probabilistic analysis method and a performance-based seismic safety evaluation for high concrete faced rockfill dam (CFRD). Combined with random sample generation and reliability analysis methods, the dynamic response characteristics and reliability level of CFRD under various random factors are comprehensively described. In Chapter 2, a random ground motion model based on spectral representation-random function and a high-dimensional random variable generation method based on GF- discrepancy are established. Combined with probability density evolution method (PDEM) and the random sample generation methods to verify its effectiveness and reliability for nonlinear complex geotechnical engineering. In Chapter 3, the dynamic response and probabilistic characteristics of high CFRD under random ground motion are revealed based on the elastoplastic analysis. A performance-based seismic safety evaluation method is established. In Chapter 4, the influence of material parameter randomness on dynamic response and seismic safety of high CFRD is studied from the perspective of stochastic dynamics and probability. In Chapter 5, the stochastic dynamic response and probability distribution of high CFRD under the coupled random action of ground motion and material parameters are systematically studied, and the performance-based seismic safety evaluation framework is improved. In Chapter 6, The stochastic dynamic response of 3D high CFRD is studied, and the failure performance index and performance level based on overstress volume ratio combined with overstress accumulation time are discussed. The performance-based seismic safety evaluation framework is further improved. In Chapter 7, combined with the finite element dynamic time-history analysis method considering the softening effect of rockfill, a performance-based seismic safety evaluation framework for dam slope stability of high CFRD under multiple random factors is systematically explored from the perspective of stochastic dynamics and probability. In Chapter 8, The performance indexes of seismic safety evaluation for high CFRDs are suggested and the corresponding performance level with probability assurance is put forward. The multi-seismic intensity - multi-performance target - failure probability performance relationship is established, and a performance-based seismic safety evaluation framework is initially formed. This book can be used as a reference for scholars studying random vibration and reliability analysis, as well as for scholars studying dam safety evaluation.
