近日，安徽省合肥市肥西县境内的引江济淮工程淠河总干渠钢结构渡槽首次通航，无人机航拍到“河上有河 船上有船”的水上立交奇观。淠河总干渠渡槽总长350米，分左右两幅，其中钢渡槽全长246米，主跨跨度达到110米，是目前世界上跨度最大的通水通航钢结构渡槽。引江济淮工程沟通我国长江和淮河两大水系，是我国跨流域、跨省重大战略性水资源配置和综合利用工程，也是全国172项重大水利工程中的标志性项目之一。

二 | 该工程从长江下游引水，向淮河中游地区补水，具有引水、排洪、通航和水生态修复等多种功能。根据计划，2023年，引江济淮工程可以全线通水通航。建成后，一方面可以让长江水送到安徽北部和河南东部地区，辐射5000多万人口；另一方面能连通长江、淮河两大黄金水道，共同形成一条平行于京杭大运河的中国第2条长度超过千公里的南北水运大通道，对于带动区域经济协调发展，加快南北经济文化交流发挥重要基础作用。    WASHINGTON -- The Treasury Department said Thursday that it has imposed its first set of sanctions on two companies that shipped Russian oil in violation of a multinational price cap.The United States, along with the European Union, countries in the Group of Seven and Australia, imposed a $60 a barrel limit last year on what Russia could charge for its oil. The cap was designed to deprive the Kremlin of revenue to fund its war in Ukraine, forcing the Russian government either to sell its oil at a discount or divert money for a costly alternative shipping network.The companies being penalized are based in the United Arab Emirates and Turkey, the department said in a statement.A ship owned by the Emirates-based company Lumber Marine carried oil priced above $75 a barrel from a Russian port. Separately, a vessel owned by Turkey-based Ice Pearl Navigation ferried oil from Russia priced at $80 a barrel. Both companies relied on U.S. service providers. As a result of the sanctions, the Biden administration is blocking the companies' ability to conduct business or access any property or financial interests in the U.S.A senior treasury official, who briefed reporters on condition of anonymity per department rules, said that the government has usually contacted a ship's flagging nation and insurer if there is even a suspicion of a violation, leading to the ship losing access to insurance or a country's registration.The official said that Russia has tried to build an alternative shipping network to avoid the cap, but that has proved to be expensive, with private analyses indicating that it has cost $35 per barrel of oil.The administration has argued that the cap has been successful, leading to a 45% drop in Russian oil tax revenue over the past year. The official said the focus of enforcing the cap will be on further increasing costs for Russia's oil industry so Moscow has less money available to support its military in Ukraine.The coalition enforcing the price cap also released a set of recommendations to improve compliance within the maritime oil industry. The guidance was aimed at countries as well as private companies. It recommends that all ships have legitimate insurance and rely on industry standard classifications, among other policies focused on stepped-up monitoring of the sector.。（总台记者 邵晶婕 合肥台 郭矗）
