| With the rapid development of China’s transportation infrastructure construction, the amount of different types of tunnel is increasing. However, due to the tunnel subjected to the influence of various factors after tunnel operation, tunnels would suffer different kinds and degrees of disease damage after a period of usage time. These diseases usually occur in the tunnel secondary lining which resulting in lining bearing capacity decline, which leading to the loss of the safety of lining. In order to solve this problem, this paper has carried out the following research work:(1) Base the basis of previous studies, this paper summarized and put forward a more comprehensive approach to the classification of tunnel lining diseases. Considering the related tunnel class specifications and other research results, suitable classification and grading standards of tunnel disease are explored in this paper, which help to provide the reference index of fuzzy evaluation method for the safety of the tunnel lining.(2) According to the domestic and foreign existing research results and relevant engineering experience, exploring suitable classification for lining disease and classification for safety factors to offer reference indexes for the existing tunnel lining safety fuzzy evaluation method(3) Making the use of the fuzzy evaluation method of lining safety into the practical engineering to verify and promote it. Providing reference for safety evaluation of tunnel lining by accurate fact and data and offer effective guidance for subsequent strengthening and reinforcing, and help to avoid hesitation whether tunnel should be treated.(4) Strengthen and reinforce tunnel lining according to the safety evaluation result of tunnel lining. And summarize previous treating methods and propose new remedial measures, and provide some advice and summed up some useful conclusions for the lining disease treating according to the practical construction situation. |
