Outline
Aiming at the two failure modes of hydraulic steel gates, the relative deformation failure under the normal service state and the bending shear composite strength failure under the limit state of bearing capacity, the corresponding failure probability analysis models were established respectively. The influence of different parameter distribution types on the failure probability of two failure modes of outcrop steel gates and deep-hole steel gates in hydraulic steel gates was explored through Monte Carlo simulations. The results show that under the same failure mode, when the coefficient of variation of the variable itself remains unchanged, the failure probabilities obtained by different distribution types are relatively close. Compared with the outcrop gate, the deep-hole gate has a higher failure probability and is more prone to instability. But the type of parameter distribution has little influence on the failure probability of deep-hole gate and has great influence on the outcrop gate. When the random variables of each parameter follow the logarithmic normal distribution, it will have a relatively maximum failure probability. It is easy to overestimate the reliability of hydraulic steel gates by considering only the normal distribution.
