In the expansion work of Hua ’ an Hydropower Station , collapse accidents are encountered during the con-struction of the diversion tunnels .Characteristics and possible causes of the collapse accidents are investigated .Treat-ment measures are then proposed , such as the good primary support , the proper construction procedure through the col-lapse rock , the deep consolidation grouting to increase the stability of surrounding rocks .Safety monitoring in the con-struction period and one-year’ s operation shows that the tunnel surrounding rocks are now stable , which illustrates the effectiveness of the proposed measures .
