Abstract：Research purposes：With construction of railway on a large scale in China, more and more railways need to pass through the salt-lake areas that are widely distributed in China. According to the engineering environment and characteristics in the Chaerhan salt-lake area, the major technical problems in construction of bridge and culvert in salt-lake are analyzed, and the primary setting principles, comprehensive anti-corrosion measures and construction methods for construction of bridge and culvert in salt-lake are presented in this paper.
Research conclusions：Based on learning the experiences in the design, research and construction of Xining-Golmud Railway, some systematic solutions to design and construction of bridges and culverts in the salt-lake area are presented. The solutions include selecting the structural type and foundation style with clear load condition, convenient construction and good durability, conducting appropriate structure treatment, using durable concrete, determining the reasonable thickness of the protecting cover for reinforcement, and taking additional measures for improving the concrete structure durability, such as reasonable using epoxy-coated steel bars, rust inhibitor, fiber concrete, silane soakage technique, anti-corrosion coating and permeable concrete for mworks.
