摘要：随着我国工程建设项目的飞速发展,边坡的土壤流失现象越来越严重,这促进各种护土固坡技术的产生^[1]。传统的护坡方式已经不能满足人们的要求。生态防护工程越来越被建设者们认同，它弥补了传统工程防护中施工难、成本高、生态效益低的缺点。生态防护主体是植物，不同的植物配比所产生的防护效果不同，对不同植物配比条件下的生态防护效果也是研究重点。本文将针对不同防护方案对边坡防护的效果进行对比分析。

Comparison of flexible protection schemes for slope plants in Haiqi Expressway

Abstract: With the rapid development of China#39;s engineering construction projects, the soil loss phenomenon of slopes is becoming more and more serious, which promotes the generation of various soil-slope-fixing techniques [1]. The traditional way of slope protection can no longer meet people#39;s requirements. Ecological protection projects are increasingly recognized by builders, which make up for the shortcomings of traditional engineering protection, such as difficult construction, high cost and low ecological benefits. The main body of ecological protection is plants, and the protective effects produced by different plant ratios are different. The ecological protection effect under different plant ratio conditions is also the research focus. This paper will compare and analyze the effects of slope protection for different protection schemes.

1. 研究的目的和意义

高速公路建设飞速发展, 低碳节能环保型高速更加引起重视^[2]。江苏省传统的高速公路护坡方式有砌石防护、抹面防护、抗滑桩防护、滑动带加固等方法等纯工程护坡的方法。中国平原地区高速公路路基边坡防护普遍采用圬工结合植草或三维网液力喷播,边沟采用圬工防护,但对于粉砂土路基边坡及边沟段,由于土质松散、土壤贫瘠,导致圬工防护施工难度大、生态效果差、施工效率低^[3]。纯工程防护方式虽然提高了安全可靠性，但生态效益和景观效果较差，且防护成本高昂，不符合当今社会生态文明发展的要求。高速公路建设的快速发展要求我们加大护坡防护技术研究力度，提供技术保障，打造精品示范工程，为全国高速公路护坡建设提供可参考、可推广的样板。
