正如前面谈到的,地震是一种普遍的自然现象,天天都在发生,只有较大的地震(五、六级以上)才会给人们带来一些灾害。实际上,地震造成的破坏主要来自三个方面,即地表的破裂、工程建筑的破坏和因水电消防等设施遭到毁坏而导致的次生灾害,下面分别举例简要说明。第一节.地表的破坏现象地裂缝:地震时地面产生裂缝是比较普遍的现象。地震引起的地裂缝主要有两种:一种是强烈地震时由于地下断层的错动使地面的岩层发生错移形成地面的断裂。这种地
As mentioned earlier, earthquakes are a common natural phenomenon that takes place every day. Only large earthquakes (above five or six) can cause some disasters. In fact, the damage caused by the earthquake mainly comes from three aspects: the rupture of the earth’s surface, the destruction of the engineering construction and the secondary disasters caused by the destruction of facilities such as hydropower and fire fighting. The following are some brief examples. Section I. Destruction phenomenon of the ground Ground fissures: It is a common phenomenon that cracks are generated on the ground during an earthquake. There are mainly two types of ground fissures caused by earthquakes. One is the fissures that form on the ground due to the misalignment of ground strata due to the dislocation of underground faults during strong earthquakes. This kind of land
