Abstract
During bridges life-cycle design and construction stage, emphasis are often on function, cost, schedule, and quality, but this ignores plan or management of protecting economy in the stage of following operation and maintenance, and this leads to successive production of considerable cost of operation and maintenance. Bridge ages in Taiwan gradually become old, what follows is huge amount of maintenance cost. However, government finance becomes tight, difficulty in maintenance and design of bridges by management unit raises day by day. Short budget plus wrong concept of bridge life-cycle cost management have directly caused bridges in Taiwan accelerate deterioration. Well use of current bridge maintenance cost has become one of the major topics of bridge management unit researches.
Most of the on-land traffics in Taiwan need to depend on bridges to connect various local areas due to the terrain. For few far counties, towns and tribes, they can only depend on bridges supporting communication with outside traffics. Therefore, bridges become indispensable important public construction; the elevated expressway bridges built inside cities provide vehicles with the function of arriving destination rapidly, this makes city traffic unhindered, reducing the traffic load caused by urbanization; however, bridges easily get damaged by earthquakes, torrential rains and other natural disasters, and by overload of vehicles and other external factors, and this could cause passer-by casualties, traffic interruption and other disasters; hence this research use Taipei “Jianguo Expressway” and “Xinsheng Expressway” as research objects, collecting maintenance cost between year 85 to year 99 to research. Investigating elevated expressway bridges each component’s ratio and content in maintenance cost, and induces key maintenance items on bridges maintenance operations, propose related plan after evaluation, provide bridges management department with executing budget plan under limited maintenance fee, and with reference of maintenance management plan.
