Finaly a stre
2、ngthening 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 design 1.Foreword To guarantee the safe and normal usage of a wharf, in addition to at d
3、esign, 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 whar
