Studies On Detection And Reinforced Technology Of Old Bridge

With the development of career of communication, highway traffic is larger and larger, there is commonly short of bridge carrying capacity, especially in 1960s and 1970s, load standard of bridge design was lower, and large parts of highway bridges were in service, they could not meet the needs of increasing traffic, whole reconstruction for them was neither in reality nor in science, so, old and dangerous bridges are needed to be repaired and reinforced, urgently. The paper studies spot detection and evaluation of bridges structure and old bridge reformation, maintenance and reinforced technology, and tests for actual bridges, it is proved from practice that, it is feasible to adopt appropriate reinforced technology, restore and raise carrying capacity and traffic capacity of old bridges, prolong use life of bridges and meet the needs of modernized communications and transportation. It is an effective way to eliminate traffic safety hidden danger, raise traffic capacity of highway and service standard, and it is also an important criterion to inspect management standard of highway departments, so it will play a major significance for continuous development of highway and bridge construction.
