This book accurately simulates the elastic displacement of rock mass under variable peak and variable frequency loading and unloading conditions. On the basis of proposing new probabilities of rock mass dynamics such as peak shifting phenomenon and the lag time of deformation rate relative to loading rate, various dynamic load conditions such as earthquakes, sudden rise and fall of water levels in reservoir areas, etc. Are simulated through different waveforms, variable frequency peak dynamic loads or cyclic loading and unloading, etc. We conducted millisecond-level simulation studies on the deformation rate, loading rate and energy of sandstone, limestone and quartz mica schist due to the role of the body. On this basis, we obtained the influence of rock type, loading waveform and other factors on millisecond-level deformation rate and energy changes. This book can be read and referenced by scientific researchers and graduate students in water conservancy and hydropower, civil engineering, mining, railways, highway transportation and other departments.
