碩士 === 國立中央大學 === 土木工程學系在職專班 === 103 === Durability and life cycle of bridge are closely connected with the environmental corrosion, every single country seriously face the durable years and safety issues of bridge, especially the coastal bridges. therefore, environment, location and the factor of corrosion are deeply considered. Now, Taiwan is using "Taiwan Bridge Management System" to record the damage status of bridges. Base on bridge inspection, we notice that the most issues are damage concrete and corrosion of steel structure. normally we use the general concrete repair method and the method of Cathodic protection for slow down the concrete from damage. Often used thermal spraying of zinc-aluminum alloy in steel as a construction method anti-corrosion coating. Discuss the relevance and effectiveness of the reasons for poor construction characteristics between, this study simulated bridges in the seaside environment corrosion coatings test.To verify the thick coating type coating (polyurea) is applied to the applicability of the coastal bridge steel corrosion. Denial of water vapor is the use of high-thickness properties. Stretch of water and drainage path mitigation pollutants invasion. Assessment project which includes : Evaluating Degree of Blistering of Paints , Chalking degree , Adhesion , Abrasion Resistance , Degree of Painted or Coated Specimens Subjected.Look forward to solve the current difficulties in the huge coastal bridge maintenance and maintenance funding.
