Analysis of reinforcement concrete Causes and prevention of vertical cracks in thin-walled abutment (pier)
In the current engineering projects, a considerable number of reinforced concrete thin-walled abutments (piers) and reinforced concrete box culvert bodies have vertical cracks with different numbers, lengths and widths during the construction process or at the initial stage of completion. In order to solve this problem, measures have been taken in the design, such as densifying reinforcement, increasing reinforcement diameter and increasing concrete grade, but the practice has proved that the situation has not been improved. Although the existence of these cracks will not affect its structural function and bearing capacity at present or in the future, if these cracks cannot stop developing or be properly treated, they will definitely have an adverse impact on the durability of the structure, especially when the structure is corroded by harmful gas or liquid or is wet The contradiction between frozen environment and coastal areas is more prominent. Due to the durability defects of concrete structures, some developed countries consume huge amounts of money every year for the maintenance of structures, which is enough to prove the importance of this problem
