摘要
酸性废石堆场存量大,危害严重,必须采用有效的覆盖及阻隔手段才能彻底消除其风险。利用电石渣作为酸性堆场的覆盖材料,既可以达到堆体封闭隔离的要求,又可以解决常规土工材料单独使用长期稳定性问题,并实现堆体的中和改良。经工程实施验证效果良好,在陡边坡酸性场地具有很好的适用性。
The acid waste rock yard has a large stock and serious harm,so effective covering and blocking measures must be adopted to completely eliminate its risks.The use of carbide slag as the covering material of acid storage yard can not only meet the requirements of the closure and isolation of the pile,but also solve the long-term stability problem of conventional geotechnical materials used alone,and realize the neutralization and improvement of the pile.The project implementation has proved that the effect is good,and it has good applicability in the acid site of steep slope.
