南水北调北沙河倒虹吸出口闸启闭机室设计

Hoist Chamber Design for the Exit Sluice of Beisha River Inverted Siphon on South-to-North Water Diversion Project

南水北调北沙河倒虹吸出口闸启闭机室具有空间跨度大,各部分高度差异大的建筑特点。通过对不同结构体系形式的比选,采用了框架结构体系。用三维空间计算模型对结构进行分析计算,较准确地反映了结构的实际受力情况,保证了结构的安全性和经济性,同时进行了抗震措施设计。

The exit sluice gate hoist chamber of Beisha River inverted siphon on South-to-North water diversion project has architecture characteristics that large space span and large height differential of each part. Comparing the different form of structural system and the structural features, using frame structure system, with 3-dimensional space model, the structure was analyzed and calculated. The actual stress state was accurately reflected, ensuring the safety and the economy. At the same time, aseismatic measure was designed.
