| Abstract: | Many factors affect the safety of high-piled wharf. The traditional safety assessment method for the high-piled wharf mainly relies on the test results of the qualitative analysis, and seldom on the accurate quantitative evaluation. In order to analyze the safety conditions of high-piled wharf accurately, this paper carries out a research on the safety assessment with reference to the safety assessment method for bridges, in which the safety assessment is divided into visual inspection assessment and bearing capacity assessment. Through the fuzzy analytic hierarchy process, the safety degree of the pier is obtained. The method is concise and can reflect accurately the safety situation of the existing high-pile pier. It provides a foundation for the management, maintenance and reinforcement of wharves. |
| Keywords: | high-piled wharf safety evaluation fuzzy analytic hierarchy process |
