Disease of bridge structure analysis And reinforcement technology
Any bridge structure always has late structural aging and more or less initial defects, which mainly include design defects (imperfect design specifications, design theories or design errors), construction defects (excessive construction errors, poor construction quality), and material defects (aging materials, poor quality) And use defects (environmental erosion, lack of maintenance, excessive use). Under the long-term effect of service load and other external influences, if the disease on the structure is not detected, repaired and strengthened, these initial defects on the structure, together with the natural aging of the structure, make the damage on the structure accumulate and develop continuously, and the function of the structure degenerates continuously, As a result, it is very likely that the structure will become a dangerous bridge after a certain service life and face the danger of damage and collapse. There are many examples in this regard, which have caused great losses to the lives and properties of the country and people.
