Abstract为同时保证植被根系生长需求和坡面稳定, 需通过试验确定植被混凝土有机质合理类型与配比。选取4种常见富含有机质材料( 稻壳、锯末、玉米酒糟、稻谷酒糟) , 以有机质类型和掺入量为变量, 分别试验研究了其对植被混凝土孔隙率和无侧限抗压强度的影响。试验结果表明: 植被混凝土孔隙率增幅随有机质配比增加而逐渐减小, 无侧限抗压强度降幅则随有机质配比增加而增大; 有机质的合理类型为小粒径粉末状有机质, 合理配比范围为7%~9%。
Other Abstract In order to simultaneously guarantee the root growth needs of vegetation and slope stability,proper types and ratios have to be determined through selection tests.Four kinds of common organic matter(rice husk,sawdust,corn vinasse,and rice vinasse) were selected to investigate the influence of different organic matter types and ratios on the porosity and unconfined compression strength of vegetation concrete.The test results show that while the porosity decreases with an increase in organic matter ratio,the unconfined compression strength increases with increasing organic matter ratio.The most reasonable type of organic matter is found to be the small size powder with a ratio ranging from 7% to 9%.
