引汉济渭秦岭输水隧洞全线贯通 关中人年内将喝上汉江水******

引汉济渭秦岭输水隧洞全线贯通。

西部网讯(记者 凌旎 马晴茹 杜鹏 宋洋)今天(2月22日)11时17分,陕西安康市宁陕县四亩地镇引汉济渭秦岭输水隧洞4号支洞内传来好消息。随着TBM(隧道硬岩掘进机)刀盘破岩而出,引汉济渭秦岭输水隧洞实现全线贯通,这标志着引汉济渭工程关键控制性工程取得重大胜利,年内可先期向西安供水,汉水穿越秦岭润泽秦川大地的美好愿景指日可待。

陕西版“南水北调” 2030年将实现配水15亿立方米

长期以来,缺水问题制约着关中、陕北的经济社会发展。因此,陕西启动了省内南水北调工程——引汉济渭工程,统筹陕西三大区域,联通长江与黄河两大水系,横穿秦岭屏障,将汉江水引入关中平原,破解陕西水资源分布不均的问题。

该工程是《渭河流域重点治理规划》中的水资源配置骨干项目、《关中——天水经济区规划》中的重大基础设施建设项目,也是国家“十三五”加快推进的172项重大水利工程之一,建成后多年平均调水规模可达15亿立方米,惠及1411万人,支撑全省1.1万亿元的国内生产总值。

引汉济渭工程分为调水工程和输配水工程两大部分,通过“一次立项、分期配水”的建设方案,将逐步实现2025年配水10亿立方米、2030年配水15亿立方米目标,以此解决关中、陕北缺水问题。

待全部完工后,引汉济渭工程会将陕南丰富的水资源调到关中地区,输送至渭河两岸的西安、咸阳、渭南、杨凌4个重点城市,西咸新区5座新城,周至、鄠邑、长安等11个中小城市及渭北工业园区等共计21个受水对象,可支撑全省1.1万亿元国内生产总值,受益人口达1411万。

首次尝试从底部横穿秦岭 施工难度世界罕见

秦岭输水隧洞是引汉济渭工程的关键控制性工程,也是人类从底部横穿秦岭的首次尝试。隧洞全长98.3千米,最大埋深2012米,设计流量70立方米每秒,纵坡1/2500,穿越地区地质条件极其复杂,众多院士、专家评价为“综合施工难度世界罕见”。

据统计,秦岭输水隧洞累计发生岩爆4000余次,其中中等等级以上3000余次,最大震级1.6级。针对超长施工通风难题,引汉济渭工程创立了完整的超长隧洞TBM法和钻爆法新的施工通风成套技术体系,创造了钻爆法无轨运输施工通风距离7.2千米、TBM法独头掘进施工通风距离16.5千米的世界纪录。

受地质地形等条件限制,秦岭输水隧洞采取钻爆法和TBM联合施工,其中钻爆法施工63.3千米,TBM施工35千米。尤其是TBM施工段,先后遭遇强岩爆、超强岩爆、断层塌方、突涌水、高温高湿、有害气体等地质灾害。

South Africa detects new COVID******

Scientists in South Africa said on Thursday they had detected a new COVID-19 variant with a large number of mutations, blaming it for a surge in infection numbers.。

The number of daily infections in Africa's hardest-hit country has increased tenfold since the start of the month.。

In response, Britain banned all travel from the country and five other southern African nations as concerns grow about the new variant, which scientists say could be more infectious than Delta and more resistant to current vaccines.。

"Unfortunately we have detected a new variant, which is a reason for concern in South Africa," virologist Tulio de Oliveira told a hastily called news conference.。

The variant, which goes by the scientific label B.1.1.529, "has a very high number of mutations," he said, adding that the World Health Organization may give it a Greek variant name – like the dominant Delta strain – on Friday.。

"It's unfortunately causing a resurgence of infections," he said.。

The variant has also been detected in Botswana and Hong Kong among travelers from South Africa, de Oliveira added.。

The WHO said it is "closely monitoring" the reported variant and is expected to meet on Friday to determine if it should be designated a variant of "interest" or of "concern."

"Early analysis shows that this variant has a large number of mutations that require and will undergo further study," the WHO added.。

'A major threat'

South African Health Minister Joe Phaahla said the variant was of "serious concern" and behind an "exponential" increase in reported cases, making it "a major threat."

The country's daily number of infections hit 1,200 on Wednesday, up from 106 earlier in the month.。

Before the detection of the new variant, authorities had predicted a fourth wave to hit South Africa starting around the middle of December, buoyed by travel ahead of the festive season.。

The government-run National Institute for Communicable Diseases said 22 positive cases of the new variant have been recorded in the country.。

The NICD said the number of detected cases and the percentage testing positive are "increasing quickly" in three of the country's provinces including Gauteng, home to the economic hub Johannesburg and the capital Pretoria.。

A cluster outbreak was recently identified, concentrated at a higher education institute in Pretoria, the NICD added.。

Last year, the Beta variant of the virus first emerged in South Africa, although until now its infection numbers have been driven by Delta, which was originally detected in India.。

South Africa has the highest pandemic numbers in Africa with around 2.95 million cases, of which 89,657 have been fatal.。

10 mutations。

Scientists said the new variant has at least 10 mutations, compared with two for Delta and three for Beta.。

"The concern is that when you have so many mutations, it can have an impact on how the virus behaves," Maria Van Kerkhove, the WHO's technical lead on COVID-19, said at a virtual press briefing.。

"It will take a few weeks for us to understand what impact this variant has on any potential vaccines," she added.。

Neutralizing the variant is "complicated by the number of mutations this variant" contains, said one of the South African scientists Penny Moore.。

"This variant contains many mutations that we are not familiar with," she added.。

The Africa Centres for Disease Control and Prevention said it will soon meet South African experts to discuss the variant.。

"There are so many variants out there but some of them are of no consequence on the trajectory of the epidemic," Africa CDC head John Nkengasong told a news conference on Thursday.。
