广州暴雨引发泥石流,泥石流灾害的预判与防治

初中家长 05-23 浏览量: 分享:

21日晚至22日早晨,广州遭遇特大暴雨,其中黄埔、增城两区灾情严重,目前已造成4人死亡。


广州市防汛防旱防风总指挥部22日公布,21日晚到22日早晨的降雨,强度大、范围广、面雨量大。据介绍,此次暴雨的小时雨的强度、范围均超历史纪录,全市小时雨强度超80毫米的有42个站次,破历史纪录;全市平均面雨量为101毫米,其中黄埔区达到176.2毫米、增城155.4毫米。黄埔区永和街录得全市最大累积雨量378.6毫米,达到百年来历史极值。此次3小时最大雨量出现在增城区新塘镇,为297毫米。


 
泥石流是指在山区或者其他沟谷深壑,地形险峻的地区,因为暴雨、暴雪或其他自然灾害引发的山体滑坡并携带有大量泥沙以及石块的特殊洪流。那么,大家知道泥石流来前有哪些征兆呢?下面一起随三好网小编来看看相关知识吧。


泥石流来前的题征兆
1.河水异常。如果河(沟)床中正常流水突然断流或洪水突然增大,并夹有较多的柴草、树木时,说明河(沟)上游已形成泥石流。
2.山体异常。山体出现很多白色水流,山坡变形、鼓包、裂缝,甚至坡上物体出现倾斜。
3.异常声响。如果在山上听到沙沙声音,但是却找不到声音的来源,这可能是沙石的松动、流动发出的声音,是泥石流即将发生的征兆。如果山沟或深谷发出轰鸣声音或有轻微的震动感,说明泥石流正在形成,必须迅速离开危险地段。
4.其他异常情况:干旱很久的土地开始积水,道路出现龟裂,公共电话亭、树木、篱笆等突然倾斜,雨下个不停,或是雨刚停下来溪水水位却急速下降等。

 
遇到泥石流怎么办?
1、立即丢弃重物,尽快逃生。
2、要迅速向垂直泥石流卷来方向的两侧(横向)跑。如泥石流由北向南卷来,就要向东、西方向跑。如果自己身处沟底,千万不要顺沟方向往上游或下游跑,更不要在凹坡处停留。
3、将压埋在泥浆或倒塌建筑物中的伤者救出后,应立即清除其口、鼻、咽喉内的泥土及痰、血等,排出体内的污水。
4、对昏迷的人,应将其侧卧,头后仰,尽量保持呼吸道的通畅;如有外伤应先采取止血、包扎、固定等方法处理,然后送医疗机构救治。


预防泥石流的措施:

※房屋不要建在沟口和沟道上。受自然条件限制,很多村庄建在山麓扇形地上。山麓扇形地是历史泥石流活动的见证,从长远的观点看,绝大多数沟谷都有发生泥石流的可能。因此,在村庄选址和规划建设过程中,房屋不能占据泄水沟道,也不宜离沟岸过近;已经占据沟道的房屋应迁移到安全地带。在沟道两侧修筑防护堤和营造防护林,可以避免或减轻因泥石流溢出沟槽而对两岸居民造成的伤害。

※不能把冲沟当作垃圾排放场。在冲沟中随意弃土、弃渣、堆放垃圾,将给泥石流的发生提供固体物源、促进泥石流的活动;当弃土、弃渣量很大时,可能在沟谷中形成堆积坝,堆积坝溃决时必然发生泥石流。因此,在雨季到来之前,最好能主动清除沟道中的障碍物,保证沟道有良好的泄洪能力。

※保护和改善山区生态环境。泥石流的产生和活动程度与生态环境质量有密切关系。一般来说,生态环境好的区域,泥石流发生的频度低、影响范围小;生态环境差的区域,泥石流发生频度高、危害范围大。提高小流域植被覆盖率,在村庄附近营造一定规模的防护林,不仅可以抑制泥石流形成、降低泥石流发生频率,而且即使发生泥石流,也多了一道保护生命财产安全的屏障。
※雨季不要在沟谷中长时间停留。雨天不要在沟谷中长时间停留;一旦听到上游传来异常声响,应迅速向两岸上坡方向逃离。雨季穿越沟谷时,先要仔细观察,确认安全后再快速通过。山区降雨普遍具有局部性特点,沟谷下游是晴天,沟谷上游不一定也是晴天,“一山分四季,十里不同天”就是群众对山区气候变化无常的生动描述,即使在雨季的晴天,同样也要提防泥石流灾害。

※泥石流监测预警。监测流域的降雨过程和降雨量(或接收当地天气预报信息),根据经验判断降雨激发泥石流的可能性;监测沟岸滑坡活动情况和沟谷中松散土石堆积情况,分析滑坡堵河及引发溃决型泥石流的危险性,下游河水突然断流,可能是上游有滑坡堵河、溃决型泥石流即将发生的前兆;在泥石流形成区设置观测点,发现上游形成泥石流后,及时向下游发出预警信号。对城镇、村庄、厂矿上游的水库和尾矿库经常进行巡查,发现坝体不稳时,要及时采取避灾措施,防止坝体溃决引发泥石流灾害。
