DOI: 10.1007/s12517-020-06078-z
Abstract: The existence of cracks complicates the scattering wave field in composite rock strata. The cracks not only affect the dynamic features of the site but also influence the displacement amplitude of the ground vibration. Therefore,… read more here.

DOI: 10.1155/2021/5514427
Abstract: It is difficult to determine the safe operation window of drilling fluid density (SOWDFD) for deep igneous rock strata. Although the formation three-pressure (pore pressure, collapse pressure, and fracture pressure) prediction method with credibility improves… read more here.
