Abstract: In order to evaluate the usability of ultra-deep water piling hammer system, a reliability research method based on Markov's theory was proposed. Firstly, according to the working characteristics and operation mechanism of the ultra-deep water piling hammer system, the system state was analyzed, the Markov model of the repairable system was established, and an appropriate method was selected to solve the steady-state availability of the system. Then, the reliability maintenance technology was introduced into the original Markov model for quantitative analysis, the system steady-state margin was solved, the system transient availability was compared and analyzed, and the influence of each transfer rate on the steady-state availability of the system was analyzed based on the control variable method, which provided theoretical guidance for the optimal configuration of system reliability. Finally, the analysis of the system's Markov process was presented in a visual interface in the MATLAB APP designer development environment. The research results show that the steady-state availability of the repairable ultradeep water pile hammer system is 0.971 207 46, and the steady-state availability of the system based on reliability maintenance is 0.999 914 34. It shows that the steady-state availability of the system is improved after reliability maintenance, which meets the requirements of practical engineering and provides some theoretical support for the localization design of ultradeep water pile hammer system.
