标准上移某地有座电力通讯微波站,在有风的时候,天线会剧烈振动,天线的安全性无法保障。之所以发生这种情况,主要是设计上有缺陷,天线与支撑构架间的结构形式有误。天线受力的作用点偏离了支撑构架,整个结构刚度不足,天线在强风中就会发生振动。后来,通过改进天线与支撑构架间的结构形式,这样的安全隐患再也没有出现。对于这种因设计不合理而产生的安全隐患,只有在设计之初从源头上加以控制,才能从根本上予以消除;而如果投入运行之后再通过后继管理来消除隐患,不仅难度大、投入多,而且效果差。从这个事例可以看出,只有把设计的标准上移,使每一个 Standard moving a microwave power station somewhere in the ground, when the wind, the antenna will be violent vibration, the antenna can not be guaranteed security. The reason why this happens is that there are mainly design flaws and the structure between the antenna and the supporting structure is in error. The point of force applied by the antenna deviates from the support structure, and the stiffness of the entire structure is insufficient, so that the antenna may vibrate in strong winds. Later, by improving the structure between the antenna and the supporting structure, such a safety hazard never appeared again. For this design unreasonable security risks, only from the beginning of the design to control from the source to be fundamentally eliminated; and put into operation through the succession of management to eliminate hidden dangers, not only difficult and invest more , And the effect is poor. As can be seen from this example, only the design standards moved up so that each one
