| Abstract: | f14, f18 fault and lamprophyre veins are developed in the top arch of tailrace surge tank in underground power- house of Jinping I hydropower station, the fault and the influence line was exposed after excavation with broken rock, strong weathering and instable surrounding rock. Pre-stressed anchor cable was designed to strengthen the support for cavity stabil- ity and construction safety. The paperrnainly introduced the construction method for anchor cable with large-angle upward hole in tailrace surge tank. |
