摘　　要：介绍瑞士在地下埋藏式压力钢管设计方面的一些设计准则和方法及其应用情况 ,并与我国现行设计方法进行了比较。以某水电工程埋藏式压力钢管为例 ,着重讨论围岩承载能力的确定和钢衬、围岩之间荷载的分配 。Taking the buried steel penstock of a hydropower station as an example,this paper presents the criteria,methods and applications in designing the underground buried steel penstocks in Switzerland.Stress is laid on the determination of bearing capacity of the adjoining rock,the distribution of loads between the steel lining and the adjoining rock and the methods for determining the length of steel lining.Comparison has been made with the existing design methods adopted in China.
