【摘要】：隨著我國(guó)西部大開發(fā)的推進(jìn),山區(qū)交通建設(shè)蓬勃發(fā)展,基建過程中產(chǎn)生大量次生裸地,水土流失現(xiàn)象嚴(yán)重。大片裸露巖質(zhì)邊坡不但帶來了安全隱患,而且因其顏色灰暗、單調(diào)對(duì)生態(tài)環(huán)境產(chǎn)生視覺污染,與我國(guó)生態(tài)文明建設(shè)理念相違背。如何快速恢復(fù)裸露的巖質(zhì)邊坡的生態(tài)并穩(wěn)固邊坡不僅是公路景觀設(shè)計(jì)的一大難題,也是山區(qū)道路行車安全的保障。基于對(duì)國(guó)內(nèi)外邊坡生態(tài)恢復(fù)技術(shù)相關(guān)文獻(xiàn)的檢索分析,提出了一種快速高效自適應(yīng)公路高陡巖質(zhì)邊坡生態(tài)恢復(fù)技術(shù)(已獲國(guó)家專利授權(quán)),并給出了該技術(shù)的詳細(xì)參數(shù)、工作原理及關(guān)鍵施工工藝。該技術(shù)解決了高陡巖質(zhì)邊坡固土難、根系缺水、綠化見效慢、綠化期短暫、施工難度大、成本高、后期需人工澆水等問題,與現(xiàn)有技術(shù)相比優(yōu)勢(shì)明顯。該生態(tài)恢復(fù)技術(shù)將植被的生長(zhǎng)和巖體的特征結(jié)合起來發(fā)揮優(yōu)勢(shì),不但可提高綠植存活率,還能穩(wěn)固邊坡。本研究成果彌補(bǔ)了現(xiàn)有邊坡生態(tài)恢復(fù)技術(shù)的不足,更適合于公路高陡巖質(zhì)邊坡的生態(tài)恢復(fù)。
[Abstract]:With the development of China's western region, the traffic construction in mountainous area is booming, a large number of secondary bare land is produced in the process of capital construction, and the phenomenon of soil and water loss is serious. Large areas of bare rock slope not only bring safety hidden danger, but also because of its dark color, monotonous visual pollution to the ecological environment, which is contrary to the concept of ecological civilization construction in China. How to quickly restore the ecology of exposed rock slope and stabilize the slope is not only a difficult problem of highway landscape design, but also a guarantee of driving safety of mountain road. Based on the retrieval and analysis of the related literatures of slope ecological restoration technology at home and abroad, a fast and efficient adaptive highway ecological restoration technology for high steep rock slope (authorized by the state patent) is proposed, and the detailed parameters of the technology are given. Working principle and key construction technology. This technique solves the problems of high steep rock slope, such as difficult to fix soil, water shortage of root system, slow effect of greening, short period of greening, high difficulty of construction, high cost, need artificial watering in the later period, and has obvious advantages compared with the existing technology. The ecological restoration technology combines the growth of vegetation with the characteristics of rock mass, which can not only improve the survival rate of green plants, but also stabilize the slope. The research results make up for the deficiency of the existing slope ecological restoration technology and are more suitable for the ecological restoration of highway high steep rock slope.
