摘　　要：水毁是埋地管道系统一种常见的环境及地质灾害,包括地面水毁和地下水毁2种基本作用形式.相对于地面水毁,地下水毁因其所具有的隐蔽性和显露于地表的滞后性,对管道系统的安全完整性构成了更高风险.根据管周土体内地下水的流态形式,将管道地下水毁划分为管道渗流水毁和管底槽流水毁2个亚类,分别阐述了它们的致灾机理及其影响因素,最后给出了辨识标志.Water damage is one of the most common environmental and geological disasters in the buried pipeline system,and the surface water damage and the groundwater damage are the two basic forms. With respect to the surface water damage,the groundwater damage has higher risk for the safety and integrity of the pipeline system because of its concealment and the time lag revealed on the surface. According to the groundwater flow pattern in the soil around the pipeline, the groundwater damage is subclassifled into the seepage damage and the groove-stream damage at the pipeline bottom. This paper expounds the damage mechanism and the influencing factors, and presents the identification mark.
