Design And Application Study On The Ecolofical Slope Protection In River Management Engineering

River is a balanced and perfect ecosystem formed after a long period of evolution under a combination of hydrological,climatic,and geographical conditions.With the development of human beings and the intervention of human activities,many uncoordinated problems have appeared in the rivers.However,many problems such as straightening,hardening,and channeling have occurred in the process of river management,resulting in the degradation of river ecosystems.It has a large negative impact on the ecological environment.In order to maintain the sustainable development of urban resources and environment along the river,the river management should pay more attention to the use of natural ecological engineering measures to maintain the ecological balance of the river.Slope protection is a transitional zone between river system and terrestrial ecology,On the basis of satisfying the flood safety of rivers,it is an important research topic to improve the ecological functions of river through the ecological slope protection of river,so as to achieve harmony between river management and ecological environment..This paper takes ecological slope protection in river management as the study object.Firstly,it analyzes the existing problems in river management and the concept of river management,and analyzes the functions that ecological slope protection can play in river management.By analyzing the various types of traditional slope protection and its drawbacks,the types,principles,advantages and disadvantages of the various types of ecological slope protection,and the applicable conditions,as well as the selection and configuration of slope plants,are introduced in detail At the same time,the design principles of ecological slope protection and several problems to be solved are analyzed,Then,taking Tianshui Xi River Comprehensive Management Project as an example,the application of ecological slope protection in urban river management project is introduced.In this project,the form of gebin cage stone covering grass is mainly used,interspersed with various forms of slope protection structure and form while ensuring anti-shock safety,ecology hydrophilic property,landscape,cultural requirements.The implemented project section is very effective.The two sides of the river are full of vitality,through the blend of water system,green space,ecological slope protection,and the organic combination of Tianshui ancient civilization and modern civilization,to creat a unique urban landscape and to form a good natural environment and a beautiful urban landscape.Finally,taking the Han River flood controling project in Yang County as an example,the application of ecological slope protection in mountainous river management project is introduced.The prefabricated articulated block slope protection + upright type masonry retaining wall structure type is used in the project.The project is currently under construction.Through specific engineering examples,it provides some reference for the specific design and selection of ecological slope protection in river management.The final conclusion is as follows:(1)The traditional slope protection only pays attention to the role of the river itself,such as flood control and impact resistance,destroying the original natural ecosystem and natural landscape,then ecological slope protection becomes a new choice in the future water conservancy design.(2)According to the comprehensive analysis of the characteristics of watershed and river evolution analysis,flow rate,current status of river sections,geological conditions,flood control standards,socio-economic development planning of the project area and surrounding environment,sub-section design and select the most suitable slope protection type on the premise of meeting flood control safety.(3)According to the analysis of the examples in this paper,urban river management pays attention to ecological and landscape effects,and the Gebin cage stone slope protection can be used as a reference.Due to the high load and limited investment,the mountainous river can refer to the prefabricated articulated block slope protection+retaining wall type.
