在高水位情况下,坝的背水坡及坡脚附近出现横贯坝身或基础的渗流孔洞,称为漏洞。漏洞出流浑水,或由清变浑,或时清时浑,均表明漏洞正在迅速扩大,土坝有可能发生塌陷,甚至有溃决的危险。因此,对待漏洞的险情,必须慎重对待,全力以赴,迅速进行抢护。针对堤坝出现的漏洞情况分析了原因及提出相应的防治措施。 In the case of high water level, seepage holes transverse to the dam body or foundation appear near the back slope and foot of the dam, which are called loopholes. Loopholes out of the muddy water, muddy or muddy, or muddy when the clear, are that loopholes are rapidly expanding, the earth dam may collapse, and even the danger of collapse. Therefore, the risk of loopholes, we must be careful treatment, go all out to speedy rush to safeguard. According to the loopholes in the embankment, the reasons are analyzed and corresponding control measures are put forward.
