1、大连海洋大学本科毕业设计外文资料及翻译外文资料及译文Analysis of Strengthening Method For High-Piled WharfsAbstract The main factors which cause the structural disease of high-piled wharfs, and the characteristic of strengthening methods are introduced and analysed taking a high-piled wharf as an example le. Finaly a strength
2、ening and rehabilitation method for the wharf is proposed, which can be used as the reference for the design of similar structural project subsequently.KEY WORDS: strengthening, high-piled wharf, structural design1.ForewordTo guarantee the safe and normal usage of a wharf, in addition to at design,
3、the construction stage provides the good inborn condition for a wharf, at use the stage to also need to catty on the long-term maintenance to a wharf. When a wharf appears the harm, aging etc. phenomenon or suffers the disaster, still need to carry on the check and examine a patient to a wharf, and
