Abstract: | The bearing capacity of a new style double layer combined steel penstocks,is proposed and analyzed for high inner or outer water pressure.Compared to the traditional steel penstocks,the new double layer penstock shows much better bearing capacities,such as: the stability of steel penstocks enhanced under external pressure,so that traditional special measures,e.g.,setting alar planks and stiffening rings can be avoided;through using the lined concrete ring to bearing external pressure,much steel material is saved;the load-bearing ratio of rock to steel pipe is obviously increased. |

Keywords: | two layer lined steel and concrete penstocks stability bearing capacity |
