n this paper, the authors introduce the construction sequence and method of replacement excavation for high arch dam in lamprophyres of f5 fault in Jinping I Hydropower Station. Then, the authors mainly discuss the support and excavation method in weak fractured zone and indicate the significance of safety monitoring to construction in bad geological section. Finally, the authors sum up the reasonable construction method for support and excavation in weak fractured zone.
