概述

陜南漢江流(liu)(liu)域出現(xian)了一次大范圍、高(gao)強度降(jiang)水(shui)(shui)過(guo)程。降(jiang)雨引起江漢干支(zhi)流(liu)(liu)漲(zhang)水(shui)(shui)，漢江安(an)康水(shui)(shui)庫(ku)(ku)入庫(ku)(ku)洪(hong)(hong)峰(feng)(feng)達到50年一遇，安(an)康水(shui)(shui)庫(ku)(ku)迎(ying)來建庫(ku)(ku)后最(zui)大入庫(ku)(ku)洪(hong)(hong)水(shui)(shui)。洪(hong)(hong)水(shui)(shui)過(guo)程峰(feng)(feng)高(gao)量大，安(an)康水(shui)(shui)庫(ku)(ku)充分發揮(hui)大型水(shui)(shui)庫(ku)(ku)攔洪(hong)(hong)、錯峰(feng)(feng)、削(xue)峰(feng)(feng)作(zuo)用，取得了顯著防洪(hong)(hong)減(jian)災效益。

科學調度發揮顯著防洪減災效益

按(an)照省(sheng)、市防指多次會商研(yan)究的(de)(de)調度方(fang)案，安(an)(an)(an)康(kang)(kang)(kang)水(shui)(shui)(shui)庫(ku)在漲水(shui)(shui)(shui)時(shi)提前預泄騰出(chu)(chu)防洪(hong)(hong)(hong)庫(ku)容、在洪(hong)(hong)(hong)峰(feng)段控制下泄量(liang)，為(wei)下游抗洪(hong)(hong)(hong)搶險救(jiu)災創造了(le)有利(li)條件。經(jing)初(chu)步(bu)分析計算，這次漢江(jiang)安(an)(an)(an)康(kang)(kang)(kang)段特大(da)洪(hong)(hong)(hong)水(shui)(shui)(shui)期間，通(tong)(tong)過(guo)對安(an)(an)(an)康(kang)(kang)(kang)水(shui)(shui)(shui)庫(ku)及時(shi)、合(he)理調度，實現了(le)三個方(fang)面(mian)的(de)(de)減(jian)災效果(guo)。一是通(tong)(tong)過(guo)削(xue)(xue)峰(feng)調節將(jiang)(jiang)可能(neng)進(jin)入(ru)安(an)(an)(an)康(kang)(kang)(kang)城(cheng)(cheng)區河段的(de)(de)25537秒立米洪(hong)(hong)(hong)峰(feng)流量(liang)，削(xue)(xue)減(jian)至19178秒立米，削(xue)(xue)峰(feng)6359秒立米，降低下游安(an)(an)(an)康(kang)(kang)(kang)站(zhan)洪(hong)(hong)(hong)峰(feng)水(shui)(shui)(shui)位達(da)3.9米，避免(mian)了(le)漢江(jiang)安(an)(an)(an)康(kang)(kang)(kang)城(cheng)(cheng)區南(nan)北兩岸和下游旬陽、白河縣城(cheng)(cheng)發(fa)生慘重損失。二是通(tong)(tong)過(guo)錯(cuo)峰(feng)調節將(jiang)(jiang)安(an)(an)(an)康(kang)(kang)(kang)站(zhan)最(zui)大(da)洪(hong)(hong)(hong)峰(feng)流量(liang)出(chu)(chu)現時(shi)間，由18日18時(shi)推遲至18日23時(shi)，滯后5小時(shi)，為(wei)安(an)(an)(an)康(kang)(kang)(kang)東壩片(pian)區3萬(wan)余(yu)名(ming)群眾全部安(an)(an)(an)全撤離贏得(de)寶貴時(shi)間。三是通(tong)(tong)過(guo)水(shui)(shui)(shui)庫(ku)攔洪(hong)(hong)(hong)作用將(jiang)(jiang)洪(hong)(hong)(hong)水(shui)(shui)(shui)總(zong)(zong)量(liang)的(de)(de)28.7%，近5.36億立方(fang)米洪(hong)(hong)(hong)水(shui)(shui)(shui)攔蓄(xu)在庫(ku)內，減(jian)小了(le)進(jin)入(ru)下游河道洪(hong)(hong)(hong)水(shui)(shui)(shui)總(zong)(zong)量(liang)，有利(li)于下游洪(hong)(hong)(hong)水(shui)(shui)(shui)平穩通(tong)(tong)過(guo)，起到減(jian)少堤防臨(lin)洪(hong)(hong)(hong)壓力的(de)(de)作用。

通過(guo)對安康水庫的科學調度，優化了天(tian)然(ran)形態(tai)下(xia)的洪水形態(tai)，給漢(han)江安康段防洪搶險工作(zuo)帶(dai)來了有效保障與轉變，防洪減(jian)災作(zuo)用顯(xian)著。

目前，水庫壩體穩定，運行良(liang)好。
