［摘要］对中国航海博物馆曲面幕墙单层索网结构进行了张拉施工模拟分析，采用合适的分级张拉方案，最终实现了以初始状态为基础、以终态找形结果为目标的过程模拟。介绍了初始状态的确定方法，在其基础上，采用3种张拉方案进行施工模拟分析，介绍了施工模拟的步骤和具体实现方法，对3种方案进行综合比较，推荐采用横竖索混合张拉方案，以确保张拉精度。

Abstract:Construction simulation analysis on singlelayer double curve cablenet curtain wall of China Maritime Museum means adopting suitable prestress construction plan to realize the process simulation based on the initial status and final formfinding result.The confirmation method for the initial status was introduced. Three tension plans were used to make the construction simulation. Simulation steps and method were presented. Synthetical comparison among three plans was made. The plan with mixing tension of vertical and horizontal cables was recommended to ensure the construction precision.

Keywords:curtain wall; curved cable-net; construction simulation; prestressing
