In addition, the quantitative correlation between fractal dimension and TCI of cracks in tunnel lining was studied. As the distribution of cracks in tunnel lining is sort of complex, it is tough to make a exact description by way of typical mathematical strategies. Fortunately, fractal theory is used to research DIN 17100 ST 52-3 the distribution of complicated graphics. It has been broadly utilized in artwork, astronomy, geography, biology, fluid dynamics, chance principle, chaos concept, and pure mathematics prior to now few decades .
The relationship of fractal dimension and the variety of intersection points was shown in Figure 7. The results illustrated that the fractal dimension elevated with the number of intersection factors in case of the identical cracks. It is affordable as the intersecting of different cracks makes the crack graphic more complex. The outcomes confirmed that the fractal dimension can characterize the distribution of cracks, and particularly establish the intersection of different cracks, which is closely related with the health situation of tunnel lining. In this part, a comparative study was performed to compare the advantages and drawbacks of TCI and fractal dimension.

The fractal dimension of cracks in a airplane might be defined intuitively thinking of them as an object too detailed to be one-dimensional, but too simple to be two-dimensional. Therefore its dimension might finest be described not by its ordinary topological dimension but by its fractal dimension, which in this case is a quantity between one and two.

- Similar phenomenon is found in the results of spans 36 and 63, where the chance can also be underestimated by the TCI.
- As the cracks are related together, the calculated fractal dimension is considerably larger.
- Since these cracks have nearly penetrate the complete lining, it’s clear that the risk is underestimated.
- Therefore, the calculated TCI is quite small.
The cracks have been extracted from the picture as shown in Figure 9c,d by a crack identification program. The cameras had been fixed on a car, and it could detect cracks with 0.2-mm resolution at a velocity of 70 km/h. The cracks had been extracted for all of the 65 spans in Hidake Tunnel, and the results of 12 typical spans were shown in Figure 10. The fundamental condition of the 12 typical spans is proven in Table 1. The fractal dimensions of those six figures have been decided to be 1.2467, 1.2685, 1.2705, 1.2874, 1.3145, and 1.3376, respectively.
The correlation between the fractal dimension and the TCI of tunnel lining was studied. As a complement to the traditional visible inspection technique, the fractal dimension of the cracks is a promising health assessment index. The fractal dimension of the cracks is a promising methodology within the health assessment of tunnel lining as proven in these tests. However, the impact factor of different elements, together with the density, width, and distribution of cracks, weren’t fully determined. More subject check data and comparative study were need to interpretation the outcomes of the fractal dimension.
Therefore, the calculated TCI is sort of small. Since these cracks have almost penetrate the entire lining, it is clear that the risk is underestimated. As the cracks are connected collectively, the calculated fractal dimension is considerably bigger. This conduct indicated that the end result by the new index is extra consistent with the actual threat of the tunnel lining.
