| Abstract: | The theorem of eq.1 that is conditionally tenable is obtained from the mathematic questions raised from the actual construction cases hereinafter; and then the relation between the slopes of the three sides in isosceles triangle is reached by eq.2, which is found to be more convenient for the engineering design, as it can convert the primal question of transcendental function into that of iterative solution, when the profile of ogee section of a spillway dam is designed. |
