Abstract

Abstract: Because of the extreme climate change, the potential flood disaster risk in the southeast coastal areas of China can not be ignored. Based on lattice Boltzmann computational fluid dynamics method, a three-dimensional simulation study of waterlogging process in tsunami impact scenario is carried out for a coastal city building complex system, and the reliability and accuracy of the numerical simulation method for the flood impact test of an ideal building complex are verified. The results show that the buildings along rivers and coastlines have obvious cloaking effect, while the buildings inside the city are less affected by floods. The layout direction and spacing distribution of buildings have obvious influence on flood paths. The small-scale simulation analysis method of urban buildings under large-scale flood scenarios solves the problems that two-dimensional models can't calculate complex flow field, topography, and turbulence, and overcomes the difficulty of three-dimensional grid division of buildings. It can provide provides technical references for flood disaster emergency management and urban building planning based on urban information model.
