Study of Disaster Prevention Design Criteria in Typhoon-Rainstorm Prone Regions of China

Abstract

With global warming and sea level rising, the frequency and intensity of typhoon-rainstorm induced disasters have been increasing. The infrastructures in typhoon-rainstorm prone area are menaced by natural hazards. This paper aimed to compare the risk level for infrastructures designed by China design code and by our proposed Multivariate Compound Extreme Value Distribution (MCEVD) model. Risk assessment of some important infrastructures in typhoon-rainstorm prone areas are performed using MCEVD as follows: disaster prevention design water level for estuarine city Shanghai and design flood volume for Three Gorges Dam (TGD).The calculation results show that risk assessment based on MCEVD is a reasonable method for engineering planning, design, construction and management.
