Abstract: Abstract:In excavation process of the water diversion tennel of Mupo Hydropower station, the collapse and water gushing were occurred. Aiming at this problem, based on analysis of the surrounding rock geology and the underground water features, some countermeasures, such as ahead ductule grouting, ahead anchor bolt support and steel sopport, were adopted. The excavation construction progress was improved effectively, and favorable economic benefit and social effect were obtained.
