大坝的作文篇1
今天我们到了风景如画的宜昌三峡。我们先去了三峡大坝,三峡公园是国家5a级公园,三峡大坝就在公园内。三峡大坝是在长江上建的,建它的目的是泄洪和发电。站在平台上看三峡大坝,真是很雄伟,这是世界上最大的水力发电站。
下个景点是一八五平台,在这里我们更近的看见了大坝。导游介绍了大坝的总特点:中间泄洪,两边发电;大船爬楼梯,小船坐电梯;动水发电,静水通航。
我们到了今天最后一个景点了,那就是“截流纪念园”。截流纪念园是纪念三次截流成功的。园里有一个10多分钟的4d电影,讲的是截流的过程:人们把“定江石”投进长江里截流。最后,我们快乐的回到住所。在路上,我们经过了可以承重690吨的大桥和西陵长江大桥。
晚上我总是睡不着,想着明天的行程……
第二天我们游玩三峡人家。三峡人家分:溪边人家、山上人家、山下人家。我们先到溪边人家——龙进溪。龙进溪是长江旁的小溪,那里的风景如画,可以看水车,听山歌。我们走到了龙进溪的顶端瀑布群了,那般景象没法比喻,太美了。我们又到了索道码头,吃了饭,就去坐索道了。在坐索道时,我看见眼前都是一片绿色,只有右边的长江的青蓝色的。
我们下山了,在大山上的我,好像蚂蚁,下了山,就感到自己变大了,这是怎么回事呢?
下山后,我依依不舍的离开了三峡宜昌,不过,外面高速公路的风景也引人注目,但是到了晚上,周围都漆黑一片。不知不觉的,我们回到了武汉,虽然已经9点多了,但,外面跟白天一样热闹……
三峡真好玩!
大坝的作文篇2
三峡大坝位于湖北省宜昌市三斗坝,是当今世界上最大的水利枢纽工程,三峡工程主要由大坝,水电站、通航建筑物三大部分组成。
大坝为混凝土重力坝,坝顶长约2309米,坝顶高程185。水电站分设左、右岸两组厂房分别安装14台和12台水轮发电机组,单机容量70万千瓦、总装机容量1820万瓦,年平均发电量846.8亿度。三峡工程动态总投资预计为2039亿元人民币。工程总工期17年,工程竣工后,水库正常蓄水位175米,防洪库容221.5亿立方米,总库量达393亿立方米,可充分发挥其长江中下游防洪体系中的关键性骨干作用,使荆江河段防洪标准由现在的十年一遇提高到了百年一遇,并将显著改善长江宜昌至重庆660公里的航道,万吨级船可直达重庆港。为什么要修三峡大坝,是因为几代伟人都想建设三峡大坝,可都没成功而且许多地方缺水,人们才会建设大坝,因为大坝可以蓄水175米,还有高94米壮观的人工大瀑布。大坝具有防洪、发电、航运、养殖、供水、旅游等巨大的综合效益。现在几代伟人的梦想终于实现了。我站在最高峰坛子岭,可以看到三峡大坝、西陵大桥和船闸。船闸也是大坝中的一项,船闸宽300多米许多的船都可以进入,没想到三峡大坝竟有这么多作用,果然是世界第一。
三峡这一人文奇观必将成为世界新的旅游看点。

大坝的作文篇4
今年研学旅行,我去了湖北省宜昌三峡大坝,三峡人家,还有清江画廊。我其中我最喜欢游玩的地点是三峡大坝。
想要更加游玩好三峡大坝,我们必须要先了解三峡大坝。三峡大坝建成于2006年,是世界第一大的水电工程,也是世界上综合效益最大的水利枢纽工程,坝高185米。它与洪水博斗,给长江下游人民带来安宁的生活!它还能发电,航运……
我们坐了过葛洲坝的游轮。快到闸门时本来飞驰的游轮渐渐慢了下来,上游闸门慢慢的慢慢的打开。我发现,那里有红绿灯呢!开着绿灯时,我们的游船随着闸内水位的上升慢慢升起,升起,升起的时候,我的心都悬空了,万一掉下去怎么办呢?当闸内水位与上游水位相同时,船走到了最高处,红绿灯慢慢变红了。这时下游闸门打开,闸内水位渐渐下降,邮轮也慢慢的往下,我悬空的心,也跟着邮轮往下,当闸门水位与下游水位相同时,船就使出了闸门。原来过闸也没什么可怕的,就是体验一次游轮长翅膀的感觉。过闸后船又恢复了飞驰的速度,我们很快就到上岸的码头。
三峡大坝是人民智慧和劳动的结晶,我爱大坝,大坝是我们中华人民的骄傲。

大坝的作文篇6
我的家乡在宜昌,位于湖北省西部,这里有闻名中外的三峡大坝,有秀丽的三峡风光,有飘香的脐橙,有清澈的江水,有好看的巴山舞,有好客的宜昌人,欢迎世界各地的人们都来旅游。
1994年12月14日,当今世界第一大水电工程——三峡大坝工程正式动工,在2009年时峻工。完工后的三峡大坝雄伟而壮丽。
三峡工程建成后所形成的水库全长660公里。1公里也就是1千米,1千米大约是绕我们深圳路小学学校操场跑5圈的长度,何况总长是660个1千米!
三峡水库正常蓄水位高程175米,有100个1.70米的人那么高,由此可想而知,水是多么深!
另外,三峡大坝和葛洲坝这两座现代奇观也成了长江三峡的新景点,为其添姿增色。集自然美景、古代遗址和现代奇迹于一身的长江三峡将一如既往地吸引和陶醉来自世界各地的游客。
雄伟的三峡大坝位于西陵峡中段的三斗坪,能抵御百年一遇的特大洪水,为保卫我们的家园做出了巨大的贡献!
雄伟的三峡大坝,宜昌的骄傲,湖北的骄傲!
