| dc.description.abstract | With economic growing in Taiwan, a lot of traffic construction and accessory facilities are established. Doubtless, bridge construction is indispensable in traffic development. However, many natural and man-made elements cause damage to bridges increasingly in Taiwan. Moreover, Taiwan is an island country and located in the seismic belt of Pacific Ocean, which is harmful to the bridges. Another factor is the heavy traffic loading. Due to these, in recent years, there are a number of bridges seriously destroyed and collapsed, which threatens safety of people in life and property. Two typical cases are rebuilt Pong-Hu Crossing-sea Bridge corroded and Kaohsiung-Pingtung Bridge collapsed in 1990. These serious cases enforce us on collecting the information of constructed bridges all the time to avoid tragedies. Therefore, to monitor or test bridges is highly emphasized.
Compared with other advanced countries in America and Europe, the reference materials of bridges monitoring in Taiwan are still deficiency, so the damage trend of the bridge is still unable to be estimated accurately. In this research, the valuable experience in other countries is referral to set rules for estimating the damage and deterioration of a domestic RC bridge; this research also hopes offering a reference on the maintenance of bridge furthermore. In short, the main research purposes are:
1. To determine the environmental influence factor of the bridge deterioration.
2. To predict the deterioration of the bridge, with the measured data from the D.E.R. &U., Visual Inspection Method and the probability model.
3. To offer suggestions on the maintenance of the bridge.
The researcher also hopes to accumulate enough bridge measurement information to build an information system for the authority concerned making the most proper judgment, mechanism of bridge management, and making people’’s safety of life and property. | en_US |
