1、国外水文测验设施与方法美国水文站建设如何?测站如何运行管理?流量测次如何布设?测验规范规定与我国有哪些差异?国外水文测验设施设备(以美、德、英等国家为例介绍水文站的测验设施设备)如巡测车、缆道、测船、测流堰、水文观测平台是啥样子?对我国有何借鉴作用?国外水文测验设施与方法美国水文站建设如何?一、发达国家的水文站一、发达国家的水文站 美国水文站与我国差别很大,美国水文测验采用巡测,水文站的概念与我国不同,其“测站”用“测验断面”也许更准确。美国的测站很少有固定设施,不象我国的测站有各种用途的站房(宿舍、办公室、食堂、活动室、会议室、餐厅、车库、仓库等)、观测房、观测道路、供电线路和设备、通讯线路

43、据自动发送至属于国家流量测验是水文站最重要的测验内容,流量测验的方式决定着水文测站的规模和管理运行。美国水文测站中约有400个,占6%的测站采用缆道测验;有约有4000多个采用桥梁测验,占60%; 约2000多个采用船测和涉水测验 ,占30% ;其他测验方式约占4%三、 流量测验设施3.0 测验方式 美国流量测验是水文站最重要的测验内容,流量测验的方式决定着水文测美国河流流量测验方法:流速面积法(电磁流速仪、多普勒、机械)、走杭ADCP、水平ADCP、非接触水面流速仪(光学、多普勒)、测流堰、水力学计算等。最常用的方法是流速面积法。这种方法测验的测量的具体内容与我国相似,即通过测量水深起点距方

44、法测量过水断面上断面面积和测量过水的水流流速,两者相乘求得流量,美国流速测量通常采用的是机械流速仪,不过美国多用旋杯流速仪(我国多用旋浆流速仪)美国河流流量测验方法:流速面积法(电磁流速仪、多普勒、机械)为了确定断面平均流速,将断面宽度分为25-30个部分,尽可能使每个宽度之间的部分流量大致相同,流量测量是测量部分宽和垂线上的水深,并测量垂线的平均流速。当垂线水深较小时采用0.6一点测速,当垂线水深较大时采用0.2,0.8两点测速,以求得垂线平均流速。通过宽度、水深和垂线平均流速计算部分流速,各部分流量之和为全断面流量。一般掌握部分流量不超过断面流量的5% USGS流量计算采用其统一的标准程序

54、的山区、荒漠、森林等地区,难以满足缆道驱动所需的动力电,加上美国流量测验次数很少,因此美国不提倡采用缆道测验。缆道测验技术研究也不多深入,缆道测验设施设备技术也不够先进,(还不如我们的缆道先进),从下图我们可以看出各种缆道相对简单与黄河70年代末水平相当,近几年为提高工作效率缆道站也有采用ADCP进行测验。如下是一组缆站图片。3.3 缆道测验Standup cableway on Colorado River at Cisco, UT.Standup cableway on Colorado R水文测验方法(设施)Cableway MeasurementsCableway Measuremen
