THE HYDROGEOLOGIC CONDITION AND DIRECTED DRAINAGE DESIGN OF NANYANG HUILONG PUMPED-STORAGE POWER STATION FACTORY BUILDING UNDER GROUND

Traditional infiltration control project discards or little discards the occurrence factor of geology structural plane,so it always gets half the result with twice the effort,or it can't apply it's original action.The drainage design of HUILONG pumped-storage power station factory building under ground based on the statistic analysis on the excavation geology material,uses the special program hunting the best direction of boreholl, adjust correspondly the quantities combining hydrogeologic present state.It proves the reinforce design method against the rock mass can achieve marked efficiency, it’s worth to popularize.
