【摘要】：隨著我國(guó)公路、鐵路、水利等基礎(chǔ)建設(shè)大規(guī)模興起,產(chǎn)生了愈來(lái)愈多的邊坡工程,邊坡防護(hù)技術(shù)也取得了長(zhǎng)足進(jìn)步。由于公眾對(duì)生態(tài)環(huán)境的重視,以及國(guó)家對(duì)綠色循環(huán)經(jīng)濟(jì)的要求和大力推廣,對(duì)邊坡防護(hù)技術(shù)提出了更高的標(biāo)準(zhǔn),邊坡防護(hù)不僅要滿足邊坡穩(wěn)定的工程要求,還要達(dá)到生態(tài)環(huán)保,故而生態(tài)護(hù)坡技術(shù)是現(xiàn)在發(fā)展的趨勢(shì)。但目前生態(tài)護(hù)坡在材料選擇和價(jià)格方面存在一些缺陷,本文將以一種新型的生態(tài)防護(hù)—草繩繩網(wǎng)為對(duì)象,運(yùn)用土力學(xué)、水力學(xué)和泥沙運(yùn)動(dòng)學(xué)的基本原理,研究分析草繩繩網(wǎng)護(hù)坡機(jī)理、坡面沖刷規(guī)律以及配套施工工藝。主要內(nèi)容有：(1)系統(tǒng)分析了目前生態(tài)護(hù)坡形式和其特點(diǎn),以及邊坡受降雨沖刷的坡壞形式,并研究得出草繩繩網(wǎng)材料的物理性能參數(shù)、制作方法和防護(hù)機(jī)理。(2)通過(guò)建立降雨沖刷模型,模擬邊坡降雨沖刷試驗(yàn),確定草繩繩網(wǎng)網(wǎng)繩直徑和間距對(duì)邊坡泥沙沖刷的影響,得出沖刷規(guī)律；通過(guò)模擬邊坡徑流試驗(yàn),確定草繩繩網(wǎng)防護(hù)對(duì)坡面徑流流速的影響規(guī)律。(3)在現(xiàn)場(chǎng)試驗(yàn)中驗(yàn)證草繩繩網(wǎng)生態(tài)防護(hù)的實(shí)際效果,草繩的抗腐蝕情況,以及草種的生長(zhǎng)情況,得出防護(hù)形式和草種的生長(zhǎng)規(guī)律的關(guān)系。(4)通過(guò)對(duì)多種植被護(hù)坡技術(shù)的比較分析,得出與草繩繩網(wǎng)防護(hù)相配套的施工工藝,制定詳細(xì)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.
