在路基边坡坡面的防护措施中,最理想的是植物防护。它可以美化路容,调节边坡土的温、湿度,起到固结和稳定边坡的作用。在草原地区更是独具优势。采取植物防护不但是必要的,可行的,而且从经济上、收益上都是合算的。一、必要性我们知道,对路基稳定性起主要作用的是水分、温度变化和风蚀。坡面遭到破坏的主要原因也是这三方面。1.草原地区降雨的主要形式是阵雨,持续时间短、次数频繁,单位时间内降雨量大,对坡面冲刷严重。往往造成路堤
In the subgrade slope protection measures, the most ideal plant protection. It can beautify the road capacity, adjust the temperature and humidity of slope soil, play the role of consolidation and stability of the slope. In the grassland area is even more unique. It is not only necessary and feasible to adopt plant protection, but also economically and profitably. First, the necessity of We know that the main role of subgrade stability is the moisture, temperature changes and wind erosion. The main reason for the slope damage is also the three aspects. 1. The main form of rainfall in the grassland areas is the showers, which have a short duration, frequent frequency, large amount of rainfall per unit time and serious erosion on the slope. Often caused embankment
