【Abstract】 The advances of dynamic mechanics experiment of rock of method loading are introduced with the common loading methods, such as the indirected methods including sonic method and Hopkins on method, the direct methods loaded by pressurized liquid and by falling hammer. Furthermore, the measurement of dilatancy parameter of rock under dynamic loading, the application of dilatancy parameter in the design of hydraulic fracturing, as well as the loseness fracturing owing to rock dilatancy to increase production of oil are presented.更多还原
