【摘要】：随着我国公路、铁路、水利等基础建设大规模兴起,产生了愈来愈多的边坡工程,边坡防护技术也取得了长足进步。由于公众对生态环境的重视,以及国家对绿色循环经济的要求和大力推广,对边坡防护技术提出了更高的标准,边坡防护不仅要满足边坡稳定的工程要求,还要达到生态环保,故而生态护坡技术是现在发展的趋势。但目前生态护坡在材料选择和价格方面存在一些缺陷,本文将以一种新型的生态防护—草绳绳网为对象,运用土力学、水力学和泥沙运动学的基本原理,研究分析草绳绳网护坡机理、坡面冲刷规律以及配套施工工艺。主要内容有：(1)系统分析了目前生态护坡形式和其特点,以及边坡受降雨冲刷的坡坏形式,并研究得出草绳绳网材料的物理性能参数、制作方法和防护机理。(2)通过建立降雨冲刷模型,模拟边坡降雨冲刷试验,确定草绳绳网网绳直径和间距对边坡泥沙冲刷的影响,得出冲刷规律；通过模拟边坡径流试验,确定草绳绳网防护对坡面径流流速的影响规律。(3)在现场试验中验证草绳绳网生态防护的实际效果,草绳的抗腐蚀情况,以及草种的生长情况,得出防护形式和草种的生长规律的关系。(4)通过对多种植被护坡技术的比较分析,得出与草绳绳网防护相配套的施工工艺,制定详细施工流程方案。
[Abstract]:With the development of highway, railway, water conservancy and other infrastructure in China, more and more slope projects have been produced, and the slope protection technology has made great progress. Due to the attention of the public to the ecological environment, as well as the national requirements for green circular economy and its promotion, the slope protection technology has been put forward a higher standard. Slope protection should not only meet the engineering requirements of slope stability, but also achieve the ecological environmental protection. Therefore, ecological slope protection technology is the trend of development. However, there are some defects in material selection and price of ecological slope protection at present. This paper will take a new type of ecological protection-grass rope network as the object, and apply the basic principles of soil mechanics, hydraulics and sediment kinematics. This paper studies and analyzes the slope protection mechanism of grass rope network, slope surface erosion law and supporting construction technology. The main contents of this paper are as follows: (1) the current ecological slope protection form and its characteristics, as well as the slope failure form of slope washed by rainfall, are systematically analyzed, and the physical performance parameters of the grass rope network material are obtained. By establishing rainfall erosion model, simulating slope rainfall scouring test, determining the influence of the diameter and spacing of grass rope mesh rope on slope sediment erosion, the erosion law is obtained, and the slope runoff test is simulated by simulating slope runoff test. The effect of rope network protection on runoff velocity on slope surface was determined. (3) the actual effect of ecological protection of grass rope network, the corrosion resistance of grass rope and the growth of grass seed were verified in the field test. Through the comparative analysis of various vegetation slope protection techniques, the construction technology matching with the grass rope network protection is obtained, and the detailed construction flow scheme is worked out.
