基于GIS的给水管网动态水力计算模型的建立与应用-周玉文

96　　　　Vol.32　No.8　2006GIS周玉文　何　敏　方　琦(,　100022)　　　基于GIS和给水管网水力计算方法,采用一种新的更符合实际的节点流量分配方法,建立了给水管网动态水力计算模型,实现了模拟结果和GIS图形信息的良好结合,解决了工况结果难以在GIS中显示和输出的问题。将模型应用于天津市津南区咸水沽镇供水管网,并将计算结果与MIKENET模拟值、EPANET2.0计算值进行比较,验证了模型的实用性。　GIS　给水管网　水力计算模型　动态EstablishmentandimplicationofGISbaseddynamichydrauliccalculationmodelforwatersupplynetworkZhouYu-wen,HeMin,FangQi(CollegeofCivilEngineering&Architecture,BeijingUniversityofTechnology,Beijing100022,China)Abstract:InthispaperanewandpracticalmethodfortheallocationofnodeflowandtoestablishaGISbaseddynamichydraulicmodelforhydrauliccalculationofwatersupplynetworkwerepresented.ThemodelworkswellwithcombinationbetweensimulatedresultsandGISgraphicalinformationaswellasthedisplayandoutputofthestateresultsinGIS,whichwashardtosolvebefore.ThismodelhasbeenappliedpracticallyinthewatersupplynetworkofXianshuiguTowninTianjinCity.ThepracticabilityofthedynamicmodelwastestedandverifiedbycomparingthecalculatedvalueswiththesimulatedvaluesofMIKENETandcalculationvaluesofEPANET2.0.Finally,theapplicationprovidedanewmethodfortheestablishmentofadynamichydraulicmodel.Keywords:GIS;Watersupplynetwork;Hydrauliccalculationmodel;Dynamic　　,GIS,,。[1,2],,,、。,GIS。1　GIS,,;,,,。1.1　GIS。,。[3]。DOI牶牨牥牣牨牫牱牳牴牤j牣cnki牣wwe牨牴牰牬牣牪牥牥牰牣牥牳牣牥牪牰　Vol.32　No.8　200697　　　GIS,、、。,,IDGIS;,ID,,,。(1)[4]:qi=QT∑ni=0CiCi(1)qi———;QT———;Ci———(GIS)。(2):qpi=Q-∑Qilik1i∑(k1ili)(2)qpi———;Q———;Qi———;li———;k1i———(、、)。1。1　1.2　GIS。,GIS(*.tab、*.ship),,、,,。,,GIS。ID;GIS,、、、、,。,GIS。,;。,:、、、。:、。(GPS)GIS,,;AutoCADGIS,AutoCADGIS;,:、。、,。,。GIS、、。1。2　GIS。GIS,,,98　　　　Vol.32　No.8　2006GIS,,1　1IDInteger621Integer632Integer64Single85Single86Character207Data158Character59Character5010Single8GIS,GIS。,,:(1)ID()。,,,,2。,。,。2　(2),,,。3　3.1　,,。,,2m3/d。8。,,。8PLC。34。3　24h4　24h3.2　,GIS,。,MIKENET(,GIS,ArcGIS*.shp)[4,5]。200412,。20052171050,27.3mH2O(1mH2O=9.8×103Pa),383m3/h。,(),,,GIS、MIKENET　Vol.32　No.8　200699　　　EPANET2.02。2　IDGISMIKENETEPANET2.0231026.0326.0326.03770127.1227.1227.12771423.9323.9323.93781026.9926.9926.99790127.0127.0127.01793425.7725.7725.77850225.9525.9525.95851425.8625.8625.86911023.6323.6323.63931623.5623.5623.561071023.0823.0823.081380126.9926.9926.991492125.9025.9025.901630726.4426.4426.441790326.1426.1426.141960225.9025.9025.902081125.9825.9825.982130326.0326.0326.032180525.7825.7825.782260325.7325.7325.732600425.0625.0625.062670225.0425.0425.043111023.8323.8323.833441025.7925.7925.793880123.7323.7323.734180223.5823.5823.584270123.5823.5823.58　　2,GIS、MIKENETEPANET2.0,GIS,。3.3　,,GIS,GISGIS。ArcGISMIKENET,56。,ArcGISMIKENET。,DN6005　ArcGIS6　MIKENET,,DN400,DN600。4　(1)GIS,。(2),SCADA,,,。(3)GIS100　　　Vol.32　No.8　2006　卿晓霞　龙腾锐(,　400045)　　　从污水处理系统过程控制、建模及故障诊断等几个方面,对近年来国内外人工智能技术在污水处理领域的应用情况进行了较全面的介绍和分析,并结合国内研究的现状对今后需进一步开展的研究工作进行了展望。　污水处理　人工智能　智能控制　　(ArtificialIntelligence,AI)。2070AI,AI,、。,。,AI、。1　,、,,:①;②;③;④;⑤。(CSTC,2005BB7250);“”(2004BA604A01)。,。、,,,、、,。,。,(),,、,、,、;()PLC、、。,。,GIS,GIS,。(4)、、、。参考文献1　,,..,1999,25(2):17～192　,..,2002,(1):37～403ChaseDV,OrmsbeeLE.Computergeneratedpumpingschedulestostaisfgoperationalobjectives.AWWA2002,85(7):37～394　IngeduldP.ModelingofwaterdistributionsystemwithMIKENET.Denmark,DHIWater&Environment,2003.125～1355　DHI.MIKENET2001Manual.Denmark,DHIWater&Environment,2001　　○E-mail:[e-mail]:20060227:20060517
