基于BIM技术的水工隧洞施工进度仿真研究

针对目前水工隧洞施工仿真模型与三维软件结合不足和未实现完整的仿真模拟2个问题,基于BIM技术开展水工隧洞施工进度仿真理论与施工进度4D化技术的研究。首先基于CATIA建立水工隧洞的三维参数化模型;再结合水工隧洞施工特点和仿真原理,建立水工隧洞施工仿真模型;最后提出水工隧洞4D实现框架。通过以上方法实现了水工隧洞施工进度的查询和施工信息的展示。实践证明,基于BIM的水工隧洞施工进度仿真模型可以实现施工进度的计算和施工强度的查询,以提高工程建设过程中的管理水平。

BIM-based Simulation on Construction Progress of Hydraulic Tunnel

Current numerical models of simulating the construction process of hydraulic tunnel perform incompletely as they are not integrated with 3D software thoroughly. In view of this, the theory and 4D technology of simulating hydraulic tunnel construction progress are studied based on BIM technology. Firstly, a 3D parametric model of hydraulic tunnel is established using CATIA, and then a simulation model for hydraulic tunnel construction is established in line with the construction characteristics and simulation principles. Finally, the 4D framework of simulating hydraulic tunnel construction is proposed. The construction progress can be inquired and the construction information can be displayed through the model. Practice has proved that the BIM-based simulation model could offer construction progress calculation and construction intensity query, thus improving management in the construction process.
