Orthogonal Enumeration Method for Optimum Seismic Strength of Water Supply Network

Abstract:

Considering the unit seismic reliability and node water head of the water supply network after the earthquake as control parameters, the method of optimum seismic strength is developed to make the system’s nodal pressure shortfall or strengthening expense minimum. According to the function requirement and earthquake disaster character of the water supply network, the system’s seismic strength is changed into optimum problem with fewer discrete varieties, and the difficulty of solving large nonlinear scheme can be avoided by adopting orthogonal enumeration method. The presented method is tested to be feasible and effective in optimum seismic strengthening of water supply network.
