概述

陜南(nan)漢江流域出現了(le)一(yi)次大(da)(da)范圍、高強度降水(shui)(shui)(shui)過程。降雨引起江漢干支流漲(zhang)水(shui)(shui)(shui)，漢江安康水(shui)(shui)(shui)庫(ku)(ku)入(ru)(ru)庫(ku)(ku)洪(hong)(hong)峰達到50年一(yi)遇，安康水(shui)(shui)(shui)庫(ku)(ku)迎來建庫(ku)(ku)后最大(da)(da)入(ru)(ru)庫(ku)(ku)洪(hong)(hong)水(shui)(shui)(shui)。洪(hong)(hong)水(shui)(shui)(shui)過程峰高量大(da)(da)，安康水(shui)(shui)(shui)庫(ku)(ku)充(chong)分發揮大(da)(da)型水(shui)(shui)(shui)庫(ku)(ku)攔洪(hong)(hong)、錯峰、削峰作用(yong)，取得了(le)顯著防(fang)洪(hong)(hong)減災(zai)效益。

科學調度發揮顯著防洪減災效益

按照省(sheng)、市(shi)防指多次會商(shang)研究的(de)調度方案，安(an)康(kang)水(shui)(shui)(shui)庫(ku)(ku)在(zai)漲水(shui)(shui)(shui)時(shi)提前預泄(xie)騰(teng)出(chu)防洪(hong)(hong)庫(ku)(ku)容、在(zai)洪(hong)(hong)峰(feng)(feng)(feng)段(duan)控制下泄(xie)量(liang)，為下游(you)(you)(you)抗(kang)洪(hong)(hong)搶險救災創造(zao)了(le)有(you)利條件。經初步分析計算(suan)，這次漢江(jiang)安(an)康(kang)段(duan)特大洪(hong)(hong)水(shui)(shui)(shui)期(qi)間，通(tong)(tong)過對安(an)康(kang)水(shui)(shui)(shui)庫(ku)(ku)及時(shi)、合理調度，實現(xian)了(le)三個方面的(de)減(jian)災效果。一(yi)是(shi)通(tong)(tong)過削(xue)峰(feng)(feng)(feng)調節將(jiang)可能進(jin)入(ru)安(an)康(kang)城(cheng)區河段(duan)的(de)25537秒(miao)立(li)米(mi)(mi)(mi)洪(hong)(hong)峰(feng)(feng)(feng)流量(liang)，削(xue)減(jian)至19178秒(miao)立(li)米(mi)(mi)(mi)，削(xue)峰(feng)(feng)(feng)6359秒(miao)立(li)米(mi)(mi)(mi)，降低下游(you)(you)(you)安(an)康(kang)站(zhan)洪(hong)(hong)峰(feng)(feng)(feng)水(shui)(shui)(shui)位達3.9米(mi)(mi)(mi)，避免了(le)漢江(jiang)安(an)康(kang)城(cheng)區南(nan)北兩岸和(he)下游(you)(you)(you)旬陽、白河縣(xian)城(cheng)發生慘重損(sun)失。二是(shi)通(tong)(tong)過錯峰(feng)(feng)(feng)調節將(jiang)安(an)康(kang)站(zhan)最(zui)大洪(hong)(hong)峰(feng)(feng)(feng)流量(liang)出(chu)現(xian)時(shi)間，由18日18時(shi)推遲(chi)至18日23時(shi)，滯后5小時(shi)，為安(an)康(kang)東壩片區3萬余名(ming)群眾(zhong)全部安(an)全撤(che)離贏得寶貴時(shi)間。三是(shi)通(tong)(tong)過水(shui)(shui)(shui)庫(ku)(ku)攔(lan)洪(hong)(hong)作(zuo)用將(jiang)洪(hong)(hong)水(shui)(shui)(shui)總量(liang)的(de)28.7%，近5.36億立(li)方米(mi)(mi)(mi)洪(hong)(hong)水(shui)(shui)(shui)攔(lan)蓄在(zai)庫(ku)(ku)內，減(jian)小了(le)進(jin)入(ru)下游(you)(you)(you)河道洪(hong)(hong)水(shui)(shui)(shui)總量(liang)，有(you)利于(yu)下游(you)(you)(you)洪(hong)(hong)水(shui)(shui)(shui)平(ping)穩通(tong)(tong)過，起到減(jian)少堤(di)防臨洪(hong)(hong)壓(ya)力的(de)作(zuo)用。

通過對安康水(shui)庫的科學調度(du)，優化了(le)天然形(xing)(xing)態下的洪(hong)水(shui)形(xing)(xing)態，給漢江安康段防洪(hong)搶險工作(zuo)帶來了(le)有效保障與(yu)轉變，防洪(hong)減(jian)災作(zuo)用顯著。

目(mu)前(qian)，水庫壩體穩定，運行良好。
