Regarding the change law of the damping ratio during cyclic shear loading, it is found that, with a rise in normal stress, the difference between the damping ratio for different cyclic shear numbers rises. As an example, there is little variation in the damping ratio across various cyclic ...
The Tongwei fault, which is not only a buried deep-rooted fault but also the seismogenic fault of the M 7.5 earthquake that occurred in 1718, is close to the sampling site [40,41]. An exploration well is first dug manually in a flat area on the platform during the process of sampling...
