我国位于世界两大地震带:太平洋地震带与欧亚地震带之间,是地震多发国家之一。据中国地震台网中心消息,中国大陆平均每年发生5级以上地震20次,6级以上地震4次,7级以上平均3年2次。而在各类自然灾害中,地震对电力工程的危害最大,具有范围广、损失大、恢复困难等特点。随着社会工业化与现代化程度的提高,人们对电力的依赖程度也越来越高。但地震灾害的一大显著特征就是对电力系统的破坏,以及由此引发的停电、停水、停产、火灾、通信中断、救援困难等一系列问题。
China is located in the world’s two major seismic zones: the Pacific Seismic Belt and the Eurasian Seismic Belt, which is one of the countries with many earthquakes. According to the China Earthquake Networks Center, an average of 20 earthquakes of magnitude 5 or above occur in mainland China each year, and earthquakes of magnitude 6 or above occur 4 times on average, while those above grade 7 have an average of 3 times and 2 times each year. In all kinds of natural disasters, the earthquake is the most harmful to power engineering, with a wide range of losses, recovery difficulties and so on. With the improvement of social industrialization and modernization, people rely more and more on electricity. However, one of the most notable features of the earthquake disaster is the destruction of the power system and the consequent series of problems such as power outage, water stoppage, production stoppage, fire, communication interruption, and rescue difficulties.
