摘要
重力式沉箱码头是港口工程中常见的一种结构形式,其稳定性直接关系到港口运营的安全与效率。在海洋环境中,波浪作用对码头结构产生的动态荷载不容忽视,波浪作用对结构的稳定性和安全性构成潜在威胁。基于数值仿真计算软件FssiCAS,建立了波浪作用下重力式沉箱码头的动态响应分析模型,通过数值计算,得到了不同波浪条件下的码头结构位移、应力等动态响应特性。研究结果表明:波浪作用下重力式沉箱码头的位移响应呈现明显的周期性变化,且随着波高的增大以及周期的增加,位移幅值显著增大。在应力方面,临近沉箱的回填土区域产生应力重分布,沉箱下侧地基土中出现明显的应力集中。研究结果为其他类似港口工程结构的动态响应分析提供了有益的参考与借鉴。
Gravity caisson wharves are widely utilized as a common structural type in harbour engineering,whose stability is a paramount factor for the safety and operational efficiency of port facilities.In the marine environment,wharf structures are subjected to considerable wave-induced dynamic loads,constituting a key challenge to their stability and safety.A dynamic response analysis model of a gravity caisson wharf subjected to wave action was established using the numerical simulation software FssiCAS.Through numerical simulations,the dynamic response characteristics of the wharf structure under various wave loads were investigated,including displacement and stress.The computed results demonstrate that distinct periodic variations are observed in the displacement response of the gravity caisson wharf under wave loads,and the displacement amplitude is found to increase significantly with wave height and period.In terms of stress distribution,stress redistribution is observed in the backfill soil adjacent to the caisson,while notable stress concentration is identified in the foundation soil beneath it.This study offers valuable insights and references regarding the dynamic response analysis of similar harbour engineering structures.
