ROCKBURST PREDICTION FROM THE PERSPECTIVE OF ENERGY RELEASE: A CASE STUDY OF A DIVERSION TUNNEL AT JINPING II HYDROPOWER STATION

Rockburst Prediction From the Perspective of Energy Release: A Case Study of a Diversion Tunnel at Jinping II Hydropower Station

As a man-made engineering hazard, it is widely accepted that the rockbursts are the result of energy release.Previous studies have examined the unloading of in-situ stress resulting from deep tunnel excavation as a quasi-static process but the transient stress variation during excavation has received less attention.This research discusses rockburst

Iterative algorithms with seminorm-induced oblique projections

A definition Cord Winder Assembly of oblique projections onto closed convex sets that use seminorms induced by diagonal matrices which may have zeros on the diagonal is introduced.Existence and uniqueness of such projections are secured via directional affinity of the sets with respect to the diagonal matrices involved.A block-iterative algorithmic
