Comparative Study on Hydraulic Simulation of Earthquake-Damaged Water Distribution System
Hydraulic simulation of earthquake-damaged water distribution system (WDS) is essential to evaluate seismic service capacity of WDS. This paper first deduces outflow models of the damages (leaks and breaks) induced by earthquake with the help of flow pattern analysis, then presents comparisons on outflow models of pipeline damages and topology models of damaged-pipeline networks. The transformations between leakage outflow and breakage outflow is obtained by conversions of minor head loss at the leak and the frictional head loss along the disconnected pipelines of the break. Model comparisons and application results shown that the outflow of the pipe leakage and breakage can be deduced from the minor head loss at the leak and the frictional head loss along the disconnected pipe, respectively.
