摘　　要：针对船闸二期永久工程外露混凝土表观质量差的通病,以浮式系船柱槽为研究对象,研究了将混凝土浇筑工艺由二次改为一次的可行性。采用有限元软件对一次浇筑模板结构力学性能进行模拟分析,同时与工程实例进行了比较。研究表明:运用有限元软件模拟计算得出的力学性能计算值满足规范要求,与实际结果吻合,验证了一次浇筑的可行性。该方法成功应用于湘祁二线船闸,可为类似船闸浮式系船柱槽的施工提供参考。To address the common problem of the poor apparent quality of exposed concrete in the second-phase permanent projects of ship locks,this study takes the floating bollard groove as the research object to investigate the feasibility of changing the concrete pouring process from two-time pouring to one-time pouring.Specifically,it simulates and analyzes the mechanical properties of the one-time pouring formwork structure with finite-element software and compares the results with those of engineering examples.This research shows that mechanical properties calculated through finite-element software simulation meet the specification requirements and are consistent with the actual results,which verifies the feasibility of one-time pouring.The proposed method has been successfully applied to the Xiangqi second-line ship lock,and it can provide a reference for the construction of similar floating bollard grooves of ship locks.
