| Abstract: | Working device of tunnel drilling dig mostly adopts hydraulic control technology, so the reliability of drilling is influenced by reliability of hydraulic system directly. Based on systems engineering theory，the significance of general reliability of hydraulic system is discussed, and then,the reliability and characteristic values are also analyzed. Effective measures to improve the reliability of hydraulic system are proposed under the considerations of the reliability design, maintenance availability design and reliability management. |
