由于地震的发生,城市公用设施遭到破坏,诸如供水、供电瘫痪,道路桥梁破坏,通讯中断,煤气热力停止运行,致使人们生活受到严重威胁,因此近几年来引起各国学者的重视.因为这些工程设施与人们的生命有密切关系,所以被称为生命线地震工程. Due to the earthquake, the public facilities in the city were damaged, such as water supply, power supply, road and bridge destruction, communication disruption, and the thermal shutdown of the gas. As a result, people’s lives were seriously threatened. Therefore, scholars of various countries have paid attention in recent years because of these projects. Facilities are closely related to people’s lives, so it is called Lifeline Earthquake Engineering.
