直埋压力钢管槽钢形式加劲环设计

Design of Direct Burial Penstock Channel Type Stiffening Ring

本文对直埋压力钢管设计中采用槽钢作为加劲环时的抗外压验算公式进行了推导并作了计算,并对不同布置形式的槽钢加劲环方案的优劣进行了分析与说明,为采用槽钢制作的加劲环设计提供了一定的依据。

In the paper,external pressure resistance checking formula in direct burial penstock designed with channel steel as stiffening ring is derived and calculated. Advantages and disadvantages of channel steel stiffening ring plans in different layout forms are analyzed and described,and it provides certain basis for designing stiffening which is ring made of channel steel.
