基于BIM技术的闸后流态优化水工模型试验

航塘港泵闸坐落于航塘港与杭州湾交汇处,工程重点保障浦东片防洪除涝,同时兼具水生态环境改善、水资源调度等功能。为了保障航塘港泵闸的安稳运行,基于BIM三维模型技术,采用水工模型试验研究工程闸后水流流态,并研究流态优化方案。试验表明,BIM技术可以有效指导物理模型制作,工程采用的优化方案整流效果较好,可减小局部高流速,减轻外河防护强度。

Hydraulic Model Test of Flow State Optimization behind Gate Based on BIM

The pump sluice of Hangtang Port is located at the intersection of Hangtang Port and Hangzhou Bay. The project focuses on the flood control and waterlogging control in the area of Pudong, and also has the functions of ecological environmental improvement, water resource scheduling and the others. In order to ensure the smooth and steady operation of the pump sluice of Hangtang Port, and based on BIM 3D model technology, the hydraulic model test is carried out to study the flow state behind the gate, and to study the flow state optimization scheme. The test shows that BIM technology can effectively guide the physical modeling. The rectification effect of the optimization scheme used in the project is good, which can decrease the local high flow rate and reduce the protection strength of outer rivers.
