In this paper FEM is used for stress analysis of a bifurcated penstock with a crescent rib carrying the internal water pressure and working in the embedded and open states separately.To investigate the influence of surrounding rock and concrete to the stress of bifurcated pipe, emphasis is laid on the embedded type bifurcated pipe in which both the elastic resistance pf rock around it and the gap between the pipe and backfilled concrete are taken into consideration.The step-loading and one-step-loading methods are suggested to calculate the stress of the bifurcated penstock. Rock and backfilled concrete are regarded as Winkler foundation. The stress distribution patterns thus obtained are quite similar in both methods, and the difference between the maximum values of principal stress is about 10%. Stress analysis on several kinds of surrounding rock have been made by the one-step-loading method.A useful criterion is furnished in this paper for further investigation of embedded bifurcated penstock with a crescent rib.

本文用有限单元法对受内水压作用的月牙肋钢岔管(明管和埋管状态)进行整体应力分析。 为研究围岩和混凝土对岔管应力的影响,应力分析的重点放在既考虑围岩弹性抗力,又考虑岔管和回填混凝土之间存在缝隙的埋藏式岔管上。 埋管计算按文中提出的分级加载和一次加载2种方法进行。围岩和混凝土按文克勒地基处理。2种方法计算结果:应力分布规律一致;最大主应力相差约10%。对几种不同围岩还用一次加载法进行了计算。 本文对今后进一步研究埋藏式月牙肋岔管提供了有意义的依据。
