Reinforced　concrete　pile　is　the　main　load-bearing　components　of　high　pile　wharf,　the　high　pile　wharf　by　near　field　water　explosion　load,　the　need　for　power　reinforced　concrete　pile　under　explosion　load　response　and　failure　mode　were　studied,　and　then　the　antiknock　performance　and　safety　of　high　pile　wharf　were　evaluated.　In　this　paper,　the　failure　modes　of　a　reinforced　concrete　pile　near　a　high　pile　wharf　under　water　explosion　were　studied　by　means　of　numerical　analysis.　By　comparing　with　the　empirical　formula　of　the　analysis,　the　numerical　analysis　method　was　validated.　3D　analysis　model　of　reinforced　concrete　pile　under　explosion　load　was　established,　and　the　effects　of　the　number　and　radius　of　explosion　source　depth　and　other　parameters　on　the　reinforced　concrete　pile　dynamic　response　and　failure　mode　were　researched.　Based　on　the　results　of　numerical　analysis,　the　safety　range　of　steel　antiknock　concrete　pile　was　obtained,　and　the　research　results　can　provide　reference　for　the　design　and　analysis　of　high　pile　wharf　explosion.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
