Jointly stressing multilayer-loop model for penstock analysis

Based on the current condition and developing trend of methods for analyzing a jointly stressing penstock,the jointly stressing multilayer-loop model for penstock analysis and corresponding calculation method suitable for computer processing have been presented theoretically and practically respectively. In order to easily understand this technique, the penstock at the Sayansushensk Hydropower Station in Russia is taken as an analyzed example,and its calculating results in each step by hand are given. The same example has been also analyzed. using the anisotropic layer-loop model developed by the former Soviet Union Hydraulic Research Institute and three layer loop model developed by China Institute of Water Conservancy and Hydroelectric Power Research. Comparisons among them show that the technique presented fin this paper has many advantages of higher accuracy in calculation,wider uses, and easilier application. In addition, some specifically applied problems about jointly stressing between a penstock and its surrounding rock are discussed in this paper.
