长江中游护滩服役状态评价体系
Evaluation System for the Service Status of Beach Protection in Midstream of the Yangtze River
随着长江航道建设的快速发展,维护管理好在役的航道整治建筑物成为一项重要工作。目前国内针对长江中常见的航道整治建筑物——护滩服役状态的相关研究较少。基于考虑指标模糊性的可拓云理论,建立护滩服役状态评价模型。依据监测信息、护滩历年维护经验和相关规范,构建了评价指标体系,并结合序关系法和熵权法,综合确定指标权重,经模型计算可以得到护滩所隶属的服役状态等级。将该模型应用于长江中游新九水道护滩服役状态评估,评价结果与工程实际情况吻合。验证表明,本文所建立的护滩服役状态评价模型可以正确识别护滩服役状态,指导护滩日常维护工作,推进长江航道养护智能化。
With the rapid development of the Yangtze River waterway construction, maintaining and managing the existing waterway regulation buildings has become an important task. Beach protection structures along the Yangtze River, despite their commonality, lack comprehensive research on their operational status in China. This study adopts an extension cloud theory that incorporates indicator fuzziness to establish an evaluation model for beach protection service status. Drawing from monitoring data, decades of maintenance experience and relevant specifications, we developed an evaluation index system. Utilizing a combined approach of order relationship and entropy weighting, we comprehensively determined index weights. Through model calculations, the service status level of beach protection can be accurately assessed. Application of the model to evaluate the service status of beach protection at Xinjiu Waterway in the midstream of the Yangtze River yielded consistent results with actual engineering conditions. Verification confirms the model’s accuracy in correctly identifying beach protection service status, guiding daily maintenance and promoting intelligent maintenance practices along the Yangtze River waterway.

Water quality assessment entails essentially a multi-criteria decision-making process accounting for qualitative and quantitative uncertainties and their transformation. Considering uncertainties of randomness and fuzziness in water quality evaluation, a cloud model-based assessment approach is proposed. The cognitive cloud model, derived from information science, can realize the transformation between qualitative concept and quantitative data, based on probability and statistics and fuzzy set theory. When applying the cloud model to practical assessment, three technical issues are considered before the development of a complete cloud model-based approach: (1) bilateral boundary formula with nonlinear boundary regression for parameter estimation, (2) hybrid entropy-analytic hierarchy process technique for calculation of weights, and (3) mean of repeated simulations for determining the degree of final certainty. The cloud model-based approach is tested by evaluating the eutrophication status of 12 typical lakes and reservoirs in China and comparing with other four methods, which are Scoring Index method, Variable Fuzzy Sets method, Hybrid Fuzzy and Optimal model, and Neural Networks method. The proposed approach yields information concerning membership for each water quality status which leads to the final status. The approach is found to be representative of other alternative methods and accurate.Copyright © 2016 Elsevier Inc. All rights reserved.

针对潜没式治河建筑物(潜坝、潜没导板、潜没圆柱体、护滩带等)附近的复杂水流形态,结合国内外的研究成果,对其影响下的流速分布、剪应力分布、涡流结构、紊动动能、比尺效应、分离区、糙率和潜没度等进行了综述,讨论了其冲刷、壅水等机理。相关研究结果表明:潜没建筑物对水流的扰动程度决定了其水流特性,其诱导的漩涡及回流对水流结构产生巨大影响,增大了局部河床阻力,使得综合糙率重新分布。进而指出现有研究成果及其不足之处,并结合已有成果提出展望,为后续的工程及研究工作提供参考。

On the basis of research achievements in China and abroad, we made a review on the complex flow characteristics (flow velocity, shear stress distribution, eddy flow structure, turbulent kinetic energy, scale effect, separation zone, roughness coefficient and immersion ratio) near submerged river improvement structures (submerged groyne(dikes), vanes, cylindrical and beach-protection belt). We also discussed the mechanism of scouring and backwater effects. Research results indicate that the flow characteristics are determined by the disturbance of these submerged structures to flow. The induced eddy flow and backwater greatly affect the flow structure, increase local bed resistance, and redistribute the comprehensive roughness coefficient. Finally we present the shortcomings of the achievements and put forward prospects to future research.
