Lijun Tang · Journal of Engineering of Heilongjiang University · 2011
Lifeline systems in cold regions over the entire world were rapidly developing in recent decades,particular in China,some large-scale and extra large-scale lifeline projects had been built across the cold regions since 2000.However,some natural disasters had induced huge economic and properties losses related to these lifeline systems.This paper presents some typical natural disaster events occurring in recent years which severely damaged these lifeline systems,and several key problems were also discussed to improve capacities of disaster mitigation of these infrastructure systems and its sustainable development.
