Dramatic final snowboard tune******

by Peter Mertz。

COPPER MOUNTAIN, United States, Dec. 21 (Xinhua) -- The last of two December pre-Olympic qualifying events saw drama and uncertainty unfold as snowboarding Olympians squared off in the final 2021 tune-up before the 2022 Beijing Winter Olympics.。

In the women's snowboarding superpipe finals on Saturday, Spain's Queralt Castellet was in the gold medal spot with China's Cai Xuetong in second place when Chloe Kim, the defending 2018 PyeongChang Olympic gold medalist, looked down the superpipe for her last of three runs.。

"Last run for Chloe Kim," NBC announcer Todd Richards boomed to the crowd of hundreds lining the walls of the 600-foot-long halfpipe, and more than 1,000 fans clustered at the bottom, at the Copper Mountain ski resort, located 77 miles west of Denver in the Rocky Mountains.。

"Huge pressure on this young lady," added one fan standing atop the superpipe wall, in attendance with his 10-year-old daughter.。

But Kim, who took a year off snowboarding after the PyeongChang games to concentrate on her studies at Princeton University, saved her best for last and "seemed unfazed by the pressure as she strung together a 1080, cab 900 and a perfectly executed cab 1080 to score a 96 and capture the title," the Steamboat Pilot reported.。

At the bottom, as the crowd roared in appreciation, Kim fell to her knees and was immediately mobbed by Cai, Castellet and the other women snowboard competitors, who piled on top of her with whoops and cheers of appreciation.。

"This is what makes snowboarding so special," onlooker Dave Pyle told Xinhua. "These women are fierce competitors, but above all that, they support each other regardless of the outcome. They are all class acts."

"I am never putting myself in that situation again," Kim told the audience after her dramatic come-from-behind victory. "That was horrible. I was so happy that I was able to land, seriously."

Castellet finished second, and Cai took third. Next month's Olympic qualifier at California's Mammoth Springs will decide the final spots on the U.S. ski and snowboard Olympic teams.。

On the men's side, the snowboarding superpipe drama was replaced by the uncertainty that looms over the head of snowboarding legend Shaun White, a four-time Olympian who stumbled on his first two runs and only finished seventh overall with a top score of 82.。

"Shaun White struggles again in Olympic snowboard qualifier," the San Diego Union-Tribune headline said Sunday, as "the three-time gold medalist continued to underwhelm in the 2021-22 season and is down to one remaining qualifier," the Union-Tribune said.。

"It looks like the 35-year-old icon from Carlsbad will need a discretionary pick from U.S. Ski & Snowboard to get to Beijing," the report added, noting that White was eighth two weeks ago "on this same halfpipe" at the U.S. Grand Prix.。

Japan's Yuto Totsuka won Sunday with a score of 95.5 points on his final run, followed by American Taylor Gold (92.0), Japan's Ruka Hirano (89.0), Switzerland's Jan Scherrer (88.0).。

On Sunday, Japan's Ayumu Hirano became the first person in snowboard history to land the elusive triple cork (three diagonal revolutions above the 22-foot pipe) in competition.。

"Halfpipe snowboarding has just changed," NBC's Richards announced. "This is where we're going, ladies and gentlemen. Good luck, everybody."

Aside from White, the American best positioned to prevent a Japan sweep is Gold, who finished second on the day off the strength of his very first run, Forbes said Sunday.。

"It was a highly technical run that saw Gold go McTwist, frontside 1260 with a tailgrab, his signature double Michalchuk 1080 and then a switch McTwist as a setup trick for the switch 1080," Forbes noted of team USA's best Olympic hope after White.。

In the men's snowboard superpipe final, four Americans made up the 10-man field, including White, Gold, Chase Josey and Joey Okesson.。

After his final run, White threw his goggles and gloves to the fans. "I'm so happy to put one in. Thank you everyone for being here," White told the crowd. "This is my last Dew Tour so thank you, Dew Tour. Thank you everybody here. I appreciate you!" Enditem。

贝壳称西安等37城租房子销售市场降温 西安租金稳中微涨******

  近日,贝壳研究院公布的汇报表明,目前全国各地租房子市场处在淡旺季,租房子市场迟缓降温。10月,全国各地关键40城租赁交易量降低近10%,超9成城市租赁市场降温;从租金水准看,关键40城租金指数值同比下挫0.9%,同期相比稳中微涨,但对比于2019年当期仍下挫3.7%。

  2021年10月,一线城市广州市,深圳市,新一线城市成都市,杭州市,西安市以及他二线城市大连市,合肥市等37个城市租赁市场人气值均同比减少,租赁市场降温明显。

  本月,超8成城市租金水准同比下挫,超6成城市租金小于肺炎疫情前当期。10月,杭州市,佛山市,南通市,沈阳市,苏州市,太原市及广东中山市等7个城市租金水准同比基本上差不多或微涨,一线城市及其他29个城市的租金水准同比稳中下降。对比于2019年当期,一线城市各城市租金水准稳中微涨,三线城市各城市均小于肺炎疫情前水平,二线城市中成都市,杭州市,南京市,西安市,长沙市,福州市,合肥市,南通市,厦门市,无锡市,徐州市等11个城市租金稳中微涨。

  珍珠贝预估,11月租赁市场关注度维持超低温,部分地区肺炎疫情反跳或加快本地市场降温,但对总体租赁市场的危害范畴比较有限。2021年依赖于合理的疫情防控对策,租赁市场重归传统式周期时间,预估11月降温发展趋势将持续,租金水准维持稳中下降。除此之外,因为10月中旬至今,部分地区发生肺炎疫情反跳,或将加快部分地区租赁市场降温。

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。
