... of the excavations. The behaviors of AE parameters are compared with the behaviors of stress and displacement. Furthermore, DEM simulation of the bonded particles model of the cavern is carried out using the in-situ rock deformability and strength, and initial rock stress, which are obtained from in-situ tests...

... ABSTRACT Measurements of rock stress changes induced by rock excavation were presented to be one of the main works involved in the structure safety monitoring during the rock excavation of the permanent shiplock in TGP. Three different kinds of monitoring instruments were accepted as the basic...
