前言公共事业生命线系统的地震灾害减缓工作,自1971年旧金山地震以来已迅速展开。正如1933年长滩地震促成了房屋构造新的抗震设计方法和标准一样,1971年旧金山地震标明,公共事业生命线系统的抗震设计需要采用新的方法。然而,这种方法的发展主要是在加利福尼亚取得的,公共和私立机构均意识到该地区的地震危险性很高。用这种新建立起来的方法所做的工作,大部分仅仅局限于较大的公共事业

Preface Earthquake disaster mitigation efforts in the LIFE system have been rapid since the 1971 San Francisco earthquake. Just as the 1933 Long Beach earthquake led to new earthquake-resistant design methods and standards for building structures, the 1971 San Francisco earthquake marked the need for a new approach to the seismic design of the LIFE system. However, the development of this method was mainly achieved in California, and public and private institutions are aware of the high seismic risk in the area. Much of the work done with this newly established approach is limited to larger utilities
