安谷船闸坞式结构三维有限元分析

Study on U-shape structure of Angu shiplock by 3-D FEM

针对山区河流上高水头船闸坞式结构形式,对多种荷载组合下的结构响应做了数值分析,研究了完建、检修、运行及地震工况条件下闸室段的结构变位与应力分布规律,揭示了结构的不均匀沉陷程度,以及拉、压应力的分布范围和特征值,为结构配筋和地基处理提供了依据。同时,探讨了墙后回填、基岩变形模量等敏感性因素的变化对闸室、闸基工作性态的影响。

For the high lift lock＇s U-shape structure on mountainous rivers, we carried out a numerical analysis of the structural response under various load combinations, studied the laws of structural deformation and stress distribution of the chamber section under the conditions of building＇s completio operation and earthquake, and reveals the extent of the uneven settlement, as well as n, th check and maintenance, e distribution scope and characteristic values of the tensile ＆ compressive stress, which provide the basis for structural reinforcement and foundation treatment. Moreover, we explored the influence on the working behavior of the lock chamber and foundation due to the change of sensitivity factors such as the wall-back backfilling and rock deformation modulus.
