本文从汶川大地震所听到、看到和自己亲身感受到的一些客观真实的事实,发表一点自己的看法。为什么有些房屋是直接向下陷的?为什么有些房屋是向某一方向倾倒的?为什么有些房屋被扭转了一定的角度?是不是因为地震波中的横波和纵波所造成?当纵波能量大时,房屋就上下振动而直接向下塌陷,当横波能量大时房屋就左右振动而向某一方向倒塌。当横波和纵波或它们的折射波在空间某区域相遇时互成角度,房屋就有可能被扭转。这些观点仅供大家一起讨论、参考。
This article from the Wenchuan earthquake heard, see and personally feel some of the facts and facts, express my own views. Why do some houses go down directly? Why do some houses dump in one direction? Why do some houses have been twisted to some extent? Is it because of the shear waves and longitudinal waves in seismic waves? When the compressional energy is high, Vibrate up and down and collapse directly downward, when the shear wave energy is large, the house will vibrate left and right and collapse in one direction. When the transverse and longitudinal waves or their refracted waves encounter each other in an area of space, the house may be reversed. These views are for discussion and reference.
