EKL型水文缆道设备观测资料的对比分析

Comparison Analysis of Observation Materials by EKL Type Hydrometric Cableway Equipment

近几年来,新疆伊犁水文水资源勘测局先后引进6台EKL型水文缆道设备,并分别应用于不同特性的河流,选择沙质河床和卵石河床组成断面的四个水文站进行测深、测宽及流量比测试验,通过对EKL设备的测深、测宽功能及流量实测资料进行统计分析计算,分析了该设备在沙质河床和卵石河床河流上的应用。通过分析得出:河床组成和河床质的分布对测深的影响较大,河床质粒和分布不同,对断面面积测验的影响不同,测宽误差对流量测验精度的影响不大。

In recent years, Yili branch of Xinjiang Uygur autonomous region hydrology and water resources survey bureau introduced six EKL type hydrometric cableway equipment being used in rivers with different characteristics. Four hydrological stations of sandy and pebble bed section have been chosen to make depth, width and discharge comparing measurement experiments. By making statistics analysis and calculation of depth, width and discharge date measured by EKL type hydromftric cableway equipment, it is shown that the equipment can be used in rivers with sandy bed and pebble bed, and that bed material and load distribution have bigger effects for depth measuring, different bed load and distribution will have different influences to cross-section measurements, width measurement error will have little effect on flow measuring precision.
