Dagangshan Hydropower Station is characterized as large scale, high arch dam, high bank slope and high earth-quake intensity, making it encounter with significant construction difficulties and challenges. Aiming at some key technical issues such as high dam anti-seismic safety, dam abutment excavation in valley, unloading stability of right bank slope, dam founda-tion treatment, concrete temperature control, effective measures were studied to provide technical support for the smooth construc-tion of the project. Through 9 years, effort, the mentioned problems have been solved basically. The adopted measures and solu-tions are presented in detail.
