摘　　要：针对T形地连墙结构受力影响因素复杂的问题,结合工程实例,利用STAAD软件采用竖向弹性地基梁法对码头结构进行分析。研究不同模型单元划分精度、地连墙入土深度以及回填料m值选取对地连墙结构内力的影响,结果表明:随模型单元划分精度的提高,地连墙结构海侧弯矩增大,陆侧弯矩减小,锚碇墙结构弯矩变化规律与之相反,最终两者内力趋于稳定;在踢脚稳定的前提下,随地连墙底端入土深度的增加,墙体结构海侧弯矩减小、陆侧弯矩增大、位移减小;随m取值变大,锚碇墙海侧弯矩增大、陆侧弯矩减小,且敏感度较高。研究结论可为T形地连墙码头结构的设计提供参考。Regarding the complicated factors affecting the force of T-type underground continuous wall structure,this paper analyzes the wharf structure by using the vertical elastic foundation beam method and STAAD software combined with engineering examples,and investigates the influence of different model unit division accuracy,depth of the ground wall and m value of the backfill on the structure of the T-type underground continuous wall.The results show that with the improvement of model element division accuracy,the bending moment of the underground continuous wall increases at sea side,decreases at land side,and the bending moment of the anchor wall structure changes in a contrary way.Finally,the internal forces of both structures tend to be stable.Under the premise of overturning stability,the sea side bending moment of the underground continuous wall decreases,the land side bending moment increases,and the displacement decreases as the depth of the bottom of the wall increases.With the increase of m value,the bending moment on the sea side of the anchor wall increases,decreases at land side,and the sensitivity is higher.The research conclusions can provide references for the design of wharf structure using T-type underground continuous wall.
