Slope Stochastic Dynamics

This book provides a new framework for analyzing slope nonlinear stochastic seismic dynamic response based on stochastic dynamics, considering geological parameter uncertainty, strong dynamic nonlinearity, and random ground motion. It establishes an intensity frequency non-stationary stochastic ground motion model and a spatial distribution random field model of geotechnical parameters. A seismic stability performance evaluation method of slope is proposed, verified through a seismic dynamic model test on a large complex shaking table.

This comprehensive book presents a novel framework for analyzing slope nonlinear stochastic seismic dynamic response, leveraging the power of stochastic dynamics as a theoretical tool. It delves into the intricate coupling effects of uncertainty in geological parameters, robust dynamic nonlinearity, and randomness in ground motion, thereby contributing to a more comprehensive assessment of seismic dynamic stability in slopes.

To characterize the randomness of earthquakes, a preliminary intensity frequency non-stationary stochastic ground motion model is established, drawing upon time-domain stochastic process description. This model captures the inherent variability in earthquake occurrences.

Furthermore, a spatial distribution random field model of geotechnical parameters is developed to depict the time-space variability of these crucial factors. These models serve as essential tools for understanding the complex behavior of slopes under seismic loading.

Building upon the fundamental principles of stochastic dynamics, the book establishes a seismic stability performance evaluation method for slopes. This method employs a comprehensive approach, considering various factors such as slope geometry, soil properties, and seismic excitation.

To validate and refine the proposed framework and method, extensive seismic dynamic model tests are conducted using a large complex shaking table. These tests provide valuable insights into the performance of slopes under different seismic scenarios, enabling the refinement and improvement of the proposed framework and method.

By offering a comprehensive exploration of slope nonlinear stochastic seismic dynamic response, this book not only expands our understanding of seismic dynamics but also has significant implications for seismic design and engineering practices in slope environments. It sheds new light on the development of nonlinear seismic stochastic dynamics and contributes to the advancement of seismic safety in slope engineering.
