Abstract:

In the prediction of karst-fractured groundwater, thorough and systemic research is deficient, and there are problems that the accuracy and precision is low. Research on the new technique can not catch up with the  engineering demand. For solving this problem, the advantages of the common methods were integrated, and a new integrative method feasible to karst-fractured groundwater prediction was established. First, the advanced geological forecasting methods used in tunnel construction were summarized. Then, based on the scientific process, the integrative advanced geological forecasting method for karst-fractured groundwater was established by comprehensive analysis on the advantages of all the prediction techniques. Finally, the water gush disaster was successfully forecast and earlywarning in the project example. With high systematicness and efficiency, the use of this integrative geological forecasting method makes the accuracy and precision of the prediction highly improved and gushing water disaster risk rationally evaluated, which is worthy to be generalized.
