Fractured rockmass is located in the complex geological environment where the groundwater seepage field，stress field and temperature field exist simultaneously. Because of the mutual action among the above fields，the estimation accuracy of deeply buried groundwater resource would be affected，on one hand，and the geological hazards，such as stability losing of rock mass，rock burst，water gushing and geothermal calamity would be induced in practice，on the other hand. In order to protect the deeply buried groundwater resource and predict the above disasters in engineering，a research idea about coupling among seepage，stress and temperature in fractured rockmass is presented，and a new study method is given to precaution hazards and utilize groundwater resource rationally in environmental engineering.
