      Curve Analysis of the feature should include the distance from excavation point and also the time of passing of excavation point to the target point. To do so, numerical solving method can be used. The other methods for analysis are numerical methods based on a number of assumptions. For this reason it is possible that the results of some structures to which we face practically to be beyond the reality. This research use the result of PHASE2 numerical software for analyzing the cases being studied for Dasht-e Abbas Water Transfer Tunnel and considering the main tension at least diameter replacement, the curve feature has been drawn, and the same curve has been drawn by analytic method (Various Theories). Comparing and analyzing these two curves express the change in land feature curve from linear-non liner status in the analytic method to non-linear ? linear- non-linear in numerical method. Meanwhile the total replacement value gained by numerical methods are consequently less than the value gained by analytic method by different theories.
   Key words: Land feature curve, numerical method, analytic method PHASE2 Software
