| Abstract: | The cracks emergence of super long underground concrete structure seriously demolishes the integrity and durability of concrete structure, becomes hidden trouble, and badly affects the waterproof function of underground structure. The different reasons of cracks emergence in underground concrete structure are analyzed, and the technical measures of crack control are presented from materials, design, construction and maintenance of structure. It can be referred for engineerers in design and construction. |
