It very much depends on your methodology, approach and design. When interpreting narrative - we are mostly considering qualitative approaches. The attached three chapters may assist; one on common qualitative methods, another qualitative data collection and the last one is qualitative data analysis. The last chapter touches on NVivo - as Popular mentions.
I think a thematic hierarchical approach can help to analyze the narratives written by the research participants. Please refer King, N., & Horrocks, C. (2010). Interviews in qualitative research. London: Sage Publications Ltd. for details. I suggest you to use NViVO http://www.qsrinternational.com/what-is-nvivo for analysis.

Danilo, you specifically refer to 'analyze of the narratives written by the participants' - perhaps a story or an account of their own experiences or in response to questions. A textual analysis may therefore be more appropriate. See attached chapter on this technique.
For an introductory approach, I recommend you the following book:
Creswell, John (2013). Qualitative inquiry & research design: Choosing among five approaches. Thousand Oaks: Sage.
In such a book, the author delineates a profile of narrative research through its systematic comparison with other four qualitative research approaches (ethnographic, phenomenological, grounded theory and cases studies) in respect to several research steps (research problem, work with theoretical grounds, design, sampling, data collection, and, of course, data analysis).
For a more focused approach, I recommend you the following works:
Czarniawska, Barbara (2004). Narratives in social science research. London: Sage.
Dwyer, Racahel; Davis, Ian & emerald, elke (Eds.) (2017). Narrative research in practice: Stories from the field. Springer Singapore.
Finally, for a fascinating collection of works challenging any apodictic expectancy about narratives construction, I strongly recommend you the following book:
Hyvärinen, Matti; Hydén, Lars-Christer; Saarenheimo, Marja & Tamboukou, Maria (Eds.) (2010). Beyond narrative coherence. Amsterdam: John Benjamins.
Good luck and success in your research project!!!!
As others have pointed out, there are a wide variety of approaches that fall under the heading of narrative. I thus would recommend choosing the specific version of narrative analysis that suits your purposes and concentrating on that.
In narrative analysis, it is often the case that you concentrate on a relatively small number of stories to make your key point. This is quite different from thematic analysis, where you typically try to summarize the core content from the entire data set.
Since it is a narrative analysis, there is the need to construct the meanings of the findings by QUOTING SOME OF THE RESPONSES to RICHLY ILLUSTRATE the phenomena studied rather than just summarizing or paraphrasing.
Powerful lessons can be gleaned from: Creswell, John (2013). Qualitative inquiry & research design: Choosing among five approaches. Thousand Oaks: Sage
