鸟瞰欧洲（2019）

Christian and Valerie must constantly reengineer safety structures
比如安装混凝土柱子和钢网
来承接坠落的巨石
such as concrete pillars and steel nets to capture falling boulders.
为了防止岩崩
It is important to inspect the structures
检查已有的结构十分重要
that have been put in place for protection against rock-falls
确保它们能正常工作
to ensure that they are still functional,
比如 没有石头掉到屏障里
and that there are not, for example, rocks that have fallen into a barrier.
但悬崖上一块最大的巨石太沉了
But the largest of the cliff's giant slabs of rock
超出了钢网的承受范围
are so heavy that nets wouldn't hold them.
地质学家克里斯蒂安和瓦莱丽
通过一个十分长♥期♥的项目
Geologists Christian and Valerie monitor the biggest rocks
监测那块最大的岩石
using an extraordinary long-term project.
他们测量了克里斯蒂安
十多年前嵌入的
They measure the exact distance between a series of metal rods
一系列金属棒之间的精确距离
Christian embedded more than a decade ago.
金属棒之间距离的改变
If the distance between the rods has changed,
会告诉他们岩石的裂缝
是否在扩大 以及扩大了多少
it tells them whether a fracture in the rock is growing, and by how much.
然后他们就能分辨出裂缝两侧的岩石
They can then tell whether rocks, either side of the fracture,
是否可能掉落
are likely to fall any time soon.
我对今天的成果很满意
I'm satisfied with today's result.
我检查的那块石头十六年来
移♥动♥的幅度都没有超过半毫米
The block that I inspected hasn't moved more than half a millimeter in 16 years.
支撑设备状态很好
The support equipment is doing a very good job.
今天的数据看起来不错
Today, the numbers look good.
山下的路面暂时是安全的
The road below is safe for now.
克里斯蒂安和瓦莱丽
开始长途跋涉回到谷底
Christian and Valerie begin the long hike back to the valley floor.
像瑞士这样多山的国家
In a mountainous country such as Switzerland,
许多崎岖不平的地形
都需要用这种方法来监测
much of the rugged landscape needs monitoring in this way
来确保山下居民的安全
to keep the people below safe.
当你这么多年都在这悬崖上漫步
(SPEAKING FRENCH) When you have roamed this cliff for so many years,
看着它的演变是一件很有意思的事情
it's interesting to see how it evolves.
瑞士北部的边境位于
一个活跃的地质裂谷顶端
Switzerland's northern border sits
on the tip of an active geological rift.
1356年 在巴塞尔城正下方
And in 1356, directly beneath the city of Basel,
这条裂缝引发了一次欧洲内陆
this rift led to one of the biggest earthquakes
最大的地震
mainland Europe has ever experienced.
大约七百年后
Nearly 700 years later,
一组工程师正在这个地震点上
a team of engineers are building Switzerland's tallest skyscraper
建造瑞士最高的摩天大楼
right over this seismic hotspot.
罗氏大厦二号♥楼
与罗氏大厦一号♥楼相邻
Roche Bau 2, big brother to the adjacent Roche Bau 1,
是一栋五十层的高塔 高205米
is a 50-story tower that is rising up 205 meters
矗立在莱茵河岸边
over the banks of the river Rhine.
一旦建成 它将成为瑞士 最大的生物技术公♥司♥
Once complete, it will form a 3,100 person headquarters
共3100人的总部所在地
for Switzerland's largest biotech company.
约尔格·凯勒是
这座巨型建筑的高级工程师
Jörg Keller is the senior engineer of this mega-building.
科学家告诉我们 像1356年 这样的地震每五百年发生一次
Scientists tell us that an earthquake like 1356 occurs every 500 years.
约尔格·凯勒
工程师
现在已经将近下一次地震的时间
So it's already due.
但没人知道具体的时间
But, of course, nobody knows when it will happen.
今天 约尔格的团队正在搬运
Today, Jörg's team is hauling
摩天大楼防震的关键部件 即耦合梁
a vital piece of the skyscraper's earthquake proofing,
到大楼的顶层
called a coupling beam, to the top of the building.
令人惊讶的是
这片钢筋混凝土板的设计目的
Astonishingly, this slab of steel-filled concrete
是在足够猛烈的地震袭击城市时断裂
is designed to break if a strong enough earthquake hits the city.
耦合梁是跨越
巨大混凝土芯的150个连梁之一
The coupling beam is one of 150 that span enormous concrete cores.
梁柱在两座塔楼内
The beams run up both towers,
像一个巨大的拉链一样
将核芯连接在一起
joining the cores together like a giant zip.
如果发生大地震 梁柱会弯曲变形
If a massive earthquake hits, the beams are designed to bend and deform,
吸收地震的能量保护周围的建筑
absorbing the energy of the quake and safeguarding the building around it.
这些耦合梁起到了缓冲区的作用
These coupling beams act as a crumple zone,
就像你所熟知的汽车碰撞区
like, you know, the crumple zone of a car.
因此 它必然会受损
Therefore, it gets damaged, yes.
但结构不会坍塌 仍将完好无损
But the structure is still intact and it doesn't collapse.
我们独特的俯瞰视角拍到了这些工人
Our unique aerial view captures the workers
他们引导耦合梁放置到正确的位置
as they carefully guide the beam into place,
几厘米之差也不容闪失
with only centimeters to spare.
当他们锁定梁柱的位置时
As they lock the beam into position,
大楼的防震核心就完成了
the building's earthquake-proof core is complete.
七个月后
Seven months later,
随着工人们添加最后一块外墙镶板
as the workers add the last of the exterior paneling,
这座破纪录的摩天大楼
经历了一场迷人的转变
this record-breaking skyscraper undergoes a mesmerizing transformation.
罗氏大厦二号♥楼建成了
Roche Bau 2 is finished.
对于约尔格和他的团队来说
这是一个巨大的成就
For Jörg and the team, it's a monumental achievement.
当然 对我来说
我未来的一生都会因此而特别
JÖRG: Of course for me it will the rest of my life, be something special.
我坐在客厅可以看见这座高塔
If I sit in my living room, I can see the tower.
这可以让我记起自己的作品
And so, that will always remind me of my work.
瑞士是一个有着惊人反差的国度
Switzerland is a land of breathtaking contrasts,
从超现代的城市到壮丽的高山峡谷
from ultra-modern cities to spectacular alpine valleys.
多亏了瑞士强大的工程技术
这个内陆小国
Thanks to Swiss engineering prowess, this small, landlocked nation
利用他们的气候和地形
has taken advantage of their climate and terrain
来挑战极限
to push the limits of what's possible,
并造就了我们今天所见的
伟大的欧洲国家
and build the European nation we see today.
