摘要
利用室内试验方法对河道淤泥气泡混合土在酸雨作用下的性质变化进行了考察。试验结果表明,河道淤泥气泡混合土的性质受酸雨影响,模拟酸雨酸性越强影响越明显。在较强酸性条件下经60 d浸泡后土体中性化速率明显提高;与气中养护条件相比较,经酸雨浸泡后河道淤泥气泡混合土强度降低,脆性化程度提高,且随着酸雨酸性程度的提高其强度下降及脆性化程度更加明显。
The experimental study on the change of properties of foamed light soil with river sludge（FMLSS） under the action of acid rain was carried out. Experimental results show that acid rain has effect on properties of FMLSS, and the stronger the acidity of simulated acid rain, the more significant the influence. It is also shown that the neutralization rate of FMLSS is higher under stronger acid condition during 60 days of immersion, and that peak strength of FMLSS decreases and brittleness degree increases after soaking in acid rain by comparing with those in the air, besides the decrease of strength and the increase of brittleness degree become more obvious with the increase of acidity of acid rain.
