Deformation Analysis of Large-Scale Rock Slopes Considering the Effect of Microseismic Events

open access: yesApplied Sciences, 2019
To research the macroscopic deformation of rock microseismic damage, a high-precision microseismic monitoring system was established on the left bank slope of the Baihetan hydropower station in Southwestern China. Based on the microseismic monitoring and
