基于Navisworks二次开发的桥梁工程施工动态可视化仿真研究
|
摘要
4D施工规划是按时间顺序显示施工过程的有效方法,可使虚拟模型易于理解,并基于此模型分析来规划施工活动顺序,使得施工过程可视化,并在项目规划、设计及建设期间发现潜在的问题,及时制定应对方案。文章根据混凝土简支箱梁桥结构和施工特点以及施工进度与资源配置关系,创建了一种描述大桥施工特点的4D仿真模型,并基于Visual Studio C#.Net平台,运用Navisworks二次开发技术开发出了某大桥的施工进度4D模拟模块,该模块包含施工过程可视化、施工进度仿真与偏差调整、施工资源配置、施工工程量输出等功能,结合国道210改线工程阿布亥沟大桥工程实际运用表明:基于Navisworks二次开发的4D施工动态仿真提高了建设管理者对施工资源的利用效率,并通过动态可视化来方便施工管理,保证了施工质量和进度。
4D construction planning is an effective method to display the construction process in chronological order,which makesthe virtual model easy to understand. Based on this model,planning the sequence of construction activities could make the construction process visible,so it is easy to discover potential problems during project planning,design and construction,and the response plan can be formulate in time. In this paper,a 4D simulation model which described the construction characteristics of the bridge was created according to the structure and construction characteristics of concrete simply supported box girder bridge and the relationship between construction schedule and resource allocation. Based on Visual Studio C#.Net platform,the 4D simulation module of the construction progress of a certain bridge was developed through secondary development technology of Navisworks. The module includes the functions of construction process visualization,construction schedule simulation and deviation adjustment,construction resource allocation,construction project quantity output,etc. Combined with the actual application of the Abuhaigou Bridge project of the Inner Mongolia National Highway 210 Reconstruction Project,it is revealed that the dynamic simulation of 4D construction based on secondary development of Navisworks improves the utilization efficiency of construction managers for construction resources,and facilitates construction management through dynamic visualization,so construction quality and progress are guaranteed.
