Researches on High-Piled Wharf Cantilever Slab Cracking Causes and Reinforcement Measures

Abstract

As a common wharf structure, the high-piled beam-slab wharf is characterized by the cantilever slab arranged at the expansion joint between the structural sections in most cases. According to wharf routine tests, cantilever slab cracking is quite common. Relying on a typical high-piled wharf, in combination with actual wharf operations, this paper conducted the numerical analysis of the cantilever slab dynamic response under the dynamic load effect with its results showing that the dynamic load is the main cause for cracking. This paper suggested blocking up with steel plates should be adopted for reinforcement and reconstruction of high-piled wharf structure cantilever slab, with its calculation results showing blocking up with steel plates can effectively resolve cantilever slab cracking.
