[0002] With the development of urban construction in my country, there are more and more new construction, reconstruction and demolition projects of roads and bridges. Among them, bridge demolition faces many problems. In addition to the mechanical transformation problems of the bridge structure itself, it often involves the protection of adjacent structures. Some bridges are located near or below high-voltage power line towers, which has a great impact on the bridge demolition work. Special protection measures need to be formulated during the demolition process.
