Abstract：The challenges of concrete structure durability at the early stage of Chinese high-speed railway construction were introduced in this work. From the five aspects of structural design, material optimization, construction control, additional anti-corrosion measures and maintenance, the durability ensuring technologies of typical concrete structures of high-speed railway bridges, tunnels and ballastless tracks were systematically elaborated. Aiming at the current construction and development requirements of high-speed railway, the development tendency of concrete structure durability technology for high-speed railway in the future is emphasized.
