| dc.description.abstract | Owing to the frequent earthquakes, humid climate and the mudflows and landslides, the military tunnels were damaged by those natural disasters in Taiwan. Besides, the service life of military tunnels is usually twenty to thirty years old, even some military tunnels are forty to fifty years old. Moreover, due to the bad factors of environment, external forces and the strict construction method in the early stages, some military tunnels were damaged and unsafe phenomena were revealed. We should improve these unusual situations as soon as possible to prevent further damages.
For the time being, there is no suitable and concrete standard for the military to deal with the inspection of tunnel damages and the choice of constructing method that makes it difficult to obtain an absolutely safe guarantee. In addition, it is common that skilled military engineer who acquainted with the military tunnels were transferred due to mission consideration or retired that they can’t stay on the same position for a long period of time. It becomes much difficult for the new recruits to deal with the damaged problems Therefore, it’s very important for our military staff to accumulate, remain and transmit the fruitful experiences and knowledge of military tunnel management. Furthermore, on the basis of wrong decision-making policies that result in the waste of budget in tunnel maintain. Consequently, due to the requirement of war preparedness, making a considerable standard for the military to maintain and manage the military tunnels is truly urgent.
Military tunnels have certain service periods, their service quality and life could be reduced by the external forces, deterioration of lining material and leakage. However, through the process of proper patch, reinforcement and maintaining, we still can lengthen the service life and promote the service quality. Therefore, the main theme of this research is analyzing the synthesis security evaluation of military tunnels and lumping together the civil maintaining experiences to insure the safety of armament tunnels, lengthen the service life of military tunnels and make the best use of the budget on maintaining military tunnels. | en_US |
