| Abstract: |
| 【Objective】The research was to study the application of fuzzy linear regression in calculating the hydrogeology parameters with the isolated-well formula and offer a new way to calculate the hydrogeology parameters.【Method】On the ground of the simplified discharge formula with the isolated-well formulas,we obfuscated the parameters of the classical linear regression,established the fuzzy linear regression model,introduced the method of the fuzzy linear regression to calculate the intervals of hydrogeology parameters with the isolated-well formula in a certain confidence level,and checked the results using examples.【Result】The results of calculation show that this fuzzy linear regression model is reliable and feasible.Meanwhile,in different confidence levels,the calculation results of the parameters have some changes,but all of them are very little,so the method presented in this paper is stable.【Conclusion】Application of fuzzy linear regression in calculating the hydrogeology parameters with the isolated-well formula is feasible. |
