| Summary: | 碩士 === 臺灣大學 === 土木工程學研究所 === 98 === Establishing a gutter-street flow system more in line with the real street appearance, building a computing algorithm of connective pipe for coupling sewer and gutter-street systems, and using some cases to introduce how the exchange works. Using NewC sewer network model, citing the theory freefall may occur in manhole, and a method of revising coefficients matrix of one-branch system, combined with links to control the exchange operator, to carry out cases simulation, confirmed the model could be used .
Part I: Establishing the flow exchange algorithm of sewer and gutter-street system, using experiment formula by Normann et al(1985), and change equation’s term into a more make sense way. Using energy equation to derive an algorithm of outlet control and inverse slope problems. After the rain fell on the streets, the water will gather to the gutter and run through the pipe into the sewer system. If the drainage system can’t work, it will make the sewer become the full pipe situation, and the flow is usually flow from sewer system into gutter-street system. The sewer system could work again after the flood released. Establishing a computing algorithm of connective pipe for coupling sewer and gutter-street systems to prove this model could work.
Part II: Solving problems of the theory freefall may occur in manhole and a method of revising coefficients matrix of one-branch system, using appearance water level to replace the water level of manhole to computation. Combining the exchange algorithm,, confirmed the model could be used .
Keyword: NewC scheme, Normann experiment equations, sewer, gutter-street, connective pipe, coupling.
