摘要
在我国北方寒冷地区道路工程施工建设中,经常会出现大量的开挖,破坏周围环境原有植被,产生大量的裸露土坡和岩石边坡,最终导致严重的水土流失和生态环境失衡。植被混凝土是近年来出现的新型护坡材料,在南方已经广泛应用,通过对植被混凝土材料选取及配合比调整,并对其进行软化及冻融循环试验,使用UTM-100伺服液压多功能材料试验系统测试试件浸水前后及冻融循环后的强度,并对其结果进行归纳分析,研究植被混凝土中水泥掺入比的变化对植被混凝土浸水前后及冻融循环后无侧限抗压强度的影响,当植被混凝土水泥掺入量达到11%时,能够满足强度要求及植被生长所需环境。
The road engineering construction in cold regions in the northern parts of our country always encounters lots of excavations. Excavations destruct the original vegetation in the surroundings, which produces lots of bare earth slope and rock slope, eventually resulting in serious water loss, soil erosion and unbalanced ecological environment. The vegetation-growing concrete appeares in recent years, which is a new type of concrete slope protection materials widely used in the south. By series of investigations towards mixing proportion experiment of vegetation-growing concrete, freeze-thaw cycle test in laboratory, the compression strength is tested by using UTM-100 servo hydraulic multifunction material testing system. By deducing and analyzing the laboratory testing results of vegetation growing concrete, the impact of cement content conditions on unconfined compression strength of vegetation growing concrete are studied. When the vegetation concrete cement content is 11%, it can meet the strength requirement and the vegetation growth required environment.
