【Abstract】 Based on the statistical analysis of relevant data, this paper advances the statistical parameters and probability distributions of the hydrostatic pressure and the water hammer of penstock, the percentage of load carrying of surrounding rock of underground penstock and the calculating model of resistance of penstock laid on downstream face of dam. These informations give valuable reference for the reliability analysis and the determination of partial coefficients of perstocks.更多还原
