摘要

侧堰是与主河道平行或以一定角度布置的建筑物，目的是通过侧河道排出多余的水，以防止河道发生洪水，并控制主河道的水位和流速。Ogee型堰是大坝和水库的重要组成部分之一。堰结构对于保证建筑物在可能发生洪水时的安全以及以可控或不可控的方式转移洪水至关重要。本研究旨在对ogee型堰作为溢洪道时的泄洪能力进行试验研究，以保证水库作为侧堰时的安全。为此，将ogee型堰与尖顶堰的承载力进行了比较。通过对两种侧堰的比较，可以看出ogee型侧堰具有较好的泄流能力。此外，还建立了ogee型侧堰的流量系数方程，并将计算值与实测结果进行了比较，验证了方程的有效性。作为比较的结果。确定R2值为0.9932，计算RMSE值为0.102 × 10−3。从R2值可以看出，用所得的堰系数计算流量的结果是比较可靠的。

Experimental analysis of discharge capacity of ogee type side weirs

Side weirs are structures placed parallel to the main channel or at certain angles in order to discharge excess water through side channels to prevent floods in the channels and to control the level and flow rate of water in the main channels. Ogee type weirs are among the most important parts of the dams and the reservoirs. Weir structures are essential to ensure the safety of the structure in case of any possible flood and to transfer the flood waters in a controlled or uncontrolled manner. In this study, it is aimed to experimentally investigate the discharge capacity of ogee type weirs used as spillways in order to ensure the safety of the reservoirs when they are used as side weirs. For this purpose, the capacity of ogee type weirs compared with sharp crested weirs. According to the comparison of the weirs, it was seen that ogee type side weirs have a better discharge capacity. In addition, a flow coefficient equation was obtained for the side weir with ogee profile and the validity of the equation was examined by comparing the values calculated by the equation with the measurement results. As a result of the comparison. R² value was determined as 0.9932 and RMSE value was calculated as 0.102x10 ⁻³. According to R² value it was seen that the calculation of discharge with the obtained weir coefficient gave quite reliable results.

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
