球墨铸铁管道的抗震与抗沉降设计

[中文适用范围]： 本文件规定了适用于可能发生地震活动和地面沉降地区的抗震、抗沉降球墨铸铁管道的设计。 它提供了一种确定和检查埋地管道电阻的方法，并给出了计算示例。 它适用于埋在地下、具有ISO 2531规定的接头的球墨铸铁管道和管件。 注：沉降不是地震或天坑的影响。 [外文原描述]： This document specifies the design of earthquake-resistant and subsidence-resistant ductile iron pipelines suitable for use in areas where seismic activity and land subsidence can be expected. It provides a means of determining and checking the resistance of buried pipelines and gives example calculations. It is applicable to ductile iron pipes and fittings with joints as specified in ISO 2531, ISO 7186 and ISO 16631 that have expansion/contraction and deflection capabilities, used in pipelines buried underground. NOTE Subsidence is not the effects of an earthquake or a sinkhole.
