| In this paper, an example is given to illustrate the calculation method of reinforced concrete pipe diameter, the diameter of the theoretical value, engineering practice and experience formula of economic diameter of pipe diameter calculation value of comparison, puts forward the design conditions of practical application in engineering, hydraulic important theory as the support, through the multi method simultaneously, fitting calculation method for pipe diameter optimization a simple and easy, according to guide the engineering practice. The constant flow of pipe diameter calculation as an example, the economic factor and technical factor constraints, the optimization of a hydraulic diameter calculation method and verified. |
