老口航运枢纽工程船闸下闸首结构三维有限元分析

摘要

An overall dock-type structure has been adopted for the bow structure of the lock under the gate in Laokou shipping hub project and based on 3rd-series mudstone.This is a very soft mudstone that is lack of loading capacity and subgrade prestress and exceeds standard deformation.The article introduces a method that use finite element program to perform 3-D analysis on the bow structure of the lock under the gate.The result proves the feasibility and optimism of this structure.%老口航运枢纽工程船闸下闸首结构采用整体坞式结构,基础置于第三系泥岩上,它属于软泥岩,具有地基承载力不足、地基应力及变形超标等特点。文章介绍老口航运枢纽工程船闸下闸首结构采用三维有限元分析计算方法,计算成果表明：船闸下闸首结构的设计与优化提供了可靠的依据。
