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

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

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 field deformation data, the seismic source ra...
