AB - The Zheduo Mountain tunnel crosses the Xianshuihe fault zone in Kangding  city. The Xianshuihe fault zone is composed of many large-scale faults and  features a complex geological structure and strong geothermal activity.  Based on geothermal drilling data, hydrogeological tests and the geothermal  geological back-ground of the study area obtained via hydrogeological  surveys and hydrogeo-chemical methods in the process of tunnel surveying,  this paper explores the exposure characteristics and distribution of  geothermal water in the study area, analyses its hydrogeochemical and  isotopic characteristics, and thoroughly studies the hydrogeological  structure of the geothermal water to explore the genetic mechanism  responsible for the formation of the geothermal water. The influence of the  geothermal water and high ground temperatures on tunnel construction is  further predicted, and practical and effective engineering treatment  suggestions are proposed.
