【摘要】：随着我国国民经济的进一步发展,水资源紧缺的矛盾日益突出,输水工程的建设及管理尤为重要。“三分建七分管”,对水利工程而言,建设是基础,管理是关键,使用是目的。工程管理的好坏,直接影响效益的高低,管理不当可能造成严重事故,给国家和人民生命财产带来不可估量的损失。在中国西北严寒、寒冷地区,输水工程出现的问题更为复杂、突出,尤其是输水明渠。因此合理利用现有的引水工程,最大限度的发挥工程效益,是迫切需要研究、解决的问题。由于影响水利工程的自然因素较复杂,工程气象、水文、地质条件、设计方案、施工质量、运行管理模式都可能是影响渠道正常运行的因素,在实际运行中可能是其中一种甚至几种因素同时作用引起的。新疆北部某大型长距离引水工程是跨流域调水工程,输水渠道包括西干渠和风克干渠,全长329公里,其中西干渠渠道全长217公里;风克干渠渠道全长112.0公里。由于输水渠道跨越了不同的地貌单元,地质条件复杂,岩性变化较大,渠道在调度运行过程中,受地下水、地质条件、渗流等影响,导致渠道结构破坏较严重,维修工程量大大增加,每年仅维修费用就达5000余万元。针对新疆北部第四系地层上的输水渠道断面型式及基础处理方式的初步分析与研究的基础上,根据课题的需要,重点选取北疆第四纪覆盖层上某大型引水工程为课题研究对象,对渠道历年产生的破坏形式、机理以及出现的问题进行分析研究,借鉴新疆类似引水渠道工程的断面型式及基础处理方案,结合引水渠道工程沿线的工程地质条件,通过相应的室内和室外相关实验,以及分析得出的成果,推荐出符合北疆第四系覆盖区引水渠道的最优断面结构型式。
[Abstract]:With the further development of China's national economy, the contradiction of water resources shortage is becoming increasingly prominent, and the construction and management of water conveyance project is particularly important. To water conservancy engineering, construction is the foundation, management is the key and use is the purpose. The quality of project management directly affects the level of benefit, and improper management may cause serious accidents and bring incalculable losses to the lives and property of the country and the people. In the cold and cold regions of northwest China, the problems in water conveyance projects are more complex and prominent, especially in open channels. Therefore, it is urgent to study and solve the problem of rational utilization of the existing diversion project and maximum benefit of the project. Due to the complexity of natural factors affecting water conservancy projects, engineering meteorology, hydrology, geological conditions, design schemes, construction quality and operation management mode may all be factors affecting the normal operation of the channel. It is possible that one or even several factors act simultaneously in actual operation. A large long-distance diversion project in the north of Xinjiang is an inter-basin water diversion project. The water conveyance channel includes the west trunk canal and the Fengke trunk canal, with a total length of 329 kilometers, of which the west trunk canal is 217 kilometers long and the Fengke trunk canal is 112.0 kilometers long. Because the water conveyance channel has crossed different geomorphological units, the geological conditions are complex, the lithology change is great, the canal is affected by groundwater, geological conditions, seepage and so on, which results in serious damage to the canal structure. The amount of maintenance works has increased greatly, and the annual maintenance cost alone amounts to more than 5000 yuan. Based on the preliminary analysis and research on the cross section type and foundation treatment method of the Quaternary strata in northern Xinjiang, according to the needs of the project, a large water diversion project on the Quaternary overburden in northern Xinjiang is selected as the research object. This paper analyzes and studies the damage form, mechanism and existing problems of the channel over the years, draws lessons from the cross-section type and basic treatment scheme of similar diversion channel projects in Xinjiang, and combines with the engineering geological conditions along the diversion channel project. Through the relevant indoor and outdoor experiments and the results obtained from the analysis, the optimal cross-section structure of the diversion canal in the Quaternary covering area of Northern Xinjiang is recommended.
