摘　　要：简要介绍了地下管线工程的地震破坏特点及类型,搜集整理了国内外地下管线工程地震破坏等级划分标准方面的有关标准、规定,对不同标准、规定进行了评述,在此基础上,以整个管网系统为评定对象,主要考虑管段破坏程度和单位长度管线破坏处数两个因素,将管网系统地震破坏细划为基本完好、轻微破坏、中等破坏、严重破坏及毁坏5个等级,给出了一套新的地下管线工程地震破坏等级划分标准。The earthquake damage characteristics and behavior of buried pipeline engineering were introduced briefly, some criteria and provisions related to the gradation of earthquake damage for buried pipeline engineering were collected and studied. Then, taking the whole pipeline system as assessed object, considering the damage state of pipe sections and the amount of pipe damage in unit length as two key factors, a new gradation criterion of earthquake damage for buried pipeline engineering is presented.
