新华社宜昌７月１２日电（记者冯国栋、李思远）１２日晚，流量为每秒５.６万立方米的洪峰抵达三峡。三峡枢纽积极发挥防洪功能，按每秒约４.２万立方米控制下泄，已拦蓄洪水约６０亿立方米。各项监测数据显示，本轮洪峰过程中，三峡枢纽建筑物、机组、船闸等各方面运行平稳。

    The xinhua news agency yichang 7 dec（Reporter FengGuoDong、LiSiYuan）12 evening，Flow of 56000 cubic meters per second peak arrived in three gorges。The three gorges project play an active flood control function，The rate of about 42000 cubic meters or control，Reduce the flood has about 6 billion cubic meters。The monitoring data shows，This flood peak in the process，The three gorges project building、unit、Lock the stable operation。

    记者从三峡枢纽调度部门了解到，本次洪峰抵达时，三峡大坝共开启６个泄洪深孔。在当前坝上水压下，每个泄洪深孔以每秒１８００立方米的流量下泄洪水。同时，三峡电站开启全部３２台７０万千瓦机组以及小型电源机组，将洪水转化为电能。电站全场瞬时最大出力达到２２４７万千瓦，基本实现满发。

    Reporters from the three gorges project scheduling department to understand，The flood peak arrived，The three gorges dam were open six discharge deep hole。In the current the dam，Each discharge deep hole 1800 cubic meters per second of the release of the flood flow。At the same time，Three gorges hydropower station open all 32 700000 kw units and small power units，Will flood into electrical energy。All the maximum output power station instantaneous reach 22.47 million kilowatts，Basically realize ManFa。

    通过泄洪深孔和机组过流，三峡枢纽下泄力度控制在每秒４.２万立方米，１／４的洪水被拦蓄到三峡水库。三峡水库水位因此迅速上涨，当晚９时许涨至１５５米，超防汛限制水位１０米，累计拦洪约６０亿立方米，防洪效果相当于运用１次荆江分洪区。

    Through the flood discharge deep hole and the unit flow，The release of the three gorges project efforts in 42000 cubic meters per second control，A quarter of the flooding was to use of the three gorges reservoir。The three gorges reservoir water level so rising quickly，That night at about 9 rise to 155 m，Flood limit water level over 10 m，LanHong accumulative total about 6 billion cubic meters，Flood control effect is equivalent to use 1 time FenHongOu river。

    洪峰到来前，国家防总和长江防总对洪峰流量和抵达时间进行了精确预测。三峡集团提前准备，加密机组巡检次数，加派值班人员，对重要设备设施进行检查和监视，并根据水头变化实时调整机组出力。三峡调度部门严格执行长江防总调度令，积极协调梯级电站运行方式和电力外送通道。三峡枢纽管理部门加强对枢纽建筑物现场巡视检查和安全监测。数据显示，三峡大坝枢纽建筑物在洪峰期间运行正常，机组设备未见异常，大坝变形、位移等主要指标未发生重大变化。

    Flood peak before coming，The office and the office of the peak flow arrived in time and accurately predict。The three gorges group ahead，Encryption unit number inspection，Send the officer on duty，To the important equipment facilities inspected and monitoring，And according to the real-time adjust head change output of generating unit。The three gorges scheduling department strict execution Yangtze river office scheduling order，Active coordination of cascade hydropower stations operation mode and power to the channel。The three gorges project management department to strengthen the building of the project inspection tour and safety monitoring。Data shows，The three gorges dam hub in the normal operation during the flood peak building，The equipment has not seen the exception，Dam deformation、Displacement and other major indexes had not occurred important changes。

    记者另从长江三峡通航管理部门了解到，此次洪峰过境期间，三峡通航部门采取了一系列防汛和通航保障措施，目前三峡船闸运行安全有序。为确保洪峰期间汛期安全，部分未达到通航标准的船舶在锚地有序待闸。三峡水利枢纽梯级调度通信中心肖舸介绍说，本次洪峰过后，预计长江上游来水会出现回落。

    The reporter from other changjiang three-gorges navigation management department to understand，The flood peak during transit，Three-gorges navigation departments to take a series of flood control and navigation security measures，At present three gorges shiplock safety operation and orderly。To ensure safety during the flood peak flood season，Is not up to the standard of navigation ships in anchorage orderly to brake。The three gorges water conservancy hub cascade scheduling communication center XiaoGe introduced said，After the flood peak，The upper Yangtze river water is expected to appear fall back。
