DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Most of tunnels in Taiwan were built by the new Austrian tunnel method. The concrete is served as secondary lining. It has only beautiful and neat functions. In theory, it won’t be stressed after construction. However, various lining anomalies are often found in the past experience. The occurrence of the lining anomalies indicates that the tunnel would still be affected by external forces after the completion of the tunnel, which will affect the integrity of the tunnel. Thus, identifying the possible causes of linings anomalies and clarifying the relevant influencing factors are important to tunnel maintenance.
The diagnosis platform integrates the data acquiring from the same period to display the tunnel lining anomaly. And comparing the differences between data in different periods can effectively discriminate crack generation. It even predicts the possible propagation of cracks in the future. The comparison of the lining surface image, crack description image and 3D tunnel model are very helpful for the visualization of the tunnel lining anomalies.
    This study establishes the tunnel lining displacement and crack generation analysis by adopting the FLAC   PFC coupled method. The appearance of cracks means that the current stress on concrete lining exceeds its allowable strength. And through the experimental design method to calibrate the representative microparameters of concrete materials. In tunnel model, FLAC is used for the surrounding rock mass and PFC is used for concrete lining. The in-situ case simulation is based on the results of micro-displacement monitoring in different periods. FLAC   PFC coupled method will be used as a diagnostic method for the causes of lining anomalies.
The lining structure abnormality diagnosis platform will effectively visualize the distribution and development trend of lining cracks. And let users have a better feeling of the lining anomalies in three-dimensional space. It is very helpful for analyzing the stress state of concrete lining and the crack propagation, and evaluating the integrity of tunnels.
