Analysis of the Influence of the Pile Foundation of a LNG Terminal Trestle on the Anti-seepage of the Seawall
In order to ensure that river-related construction does not weaken or reduce the flood control(tide)standard of seawall engineering,ensure the safety of seawall engineering and ensure the stable development of regional economy,this paper constructs a finite element model of pile foundation and seawall of a LNG wharf trestle,and uses numerical analysis to analyze the seepage stability of seawall before and after piling.The results show that the seepage slope of the seawall before piling is less than the allowable value of the code,and the seepage slope of the seawall after piling does not meet the requirements of the code,so it is necessary to take anti-seepage reinforcement measures.The hydraulic gradient of the seawall pile driving range is less than the allowable value of the specification after backfilling and compaction grouting on the back side of the seawall,which can provide reference for the design of similar projects.
