| Abstract: | | 1. | The designs as well as the total safety factor of concrete-encased steel pressure conduits of operating hydraulic structures were analyzed. | | 2. | The principles of the existing standards related to calculations of concrete-encased steel pressure conduits were analyzed. | | 3. | Methods of calculating concrete-encased steel pressure conduits (including forks and distributors), including elements of the inside steel shell and reinforced-concrete part, were developed. | | 4. | The calculation methods developed were experimental substantiated and tested during designing and constructing domestic and foreign objects. | Translated from Gidrotekhnicheskoe Stroitel'stvo No. 1, pp. 37–44, January, 1999 |
