燃煤电厂的粉煤灰和灰渣可通过与原土掺合后用于基坑回填土作业中,在一定程度上降低了建设工程成本。在满足回填土物理力学性能的基础上,本文以两个不同地区工程为例,通过室内易溶盐试验及水质简分析试验参考《岩土工程勘察规范》分析判断地下水经过掺合土处理后产生的腐蚀性等级变化。试验结果表明,地下水经过掺和土处理后各离子含量均有变化,且粉煤灰和灰渣掺和土对地下水产生的影响幅度也略有不同;不同地下水环境情况下,粉煤灰和灰渣的掺合土对原厂区地下水的腐蚀性结果判定产生的影响也不同。
Fly ash and ash from coal-fired power plants can be used in foundation pit backfilling operations after blending with original soil, reducing the construction cost to a certain extent. On the basis of meeting the physical and mechanical properties of backfill soil, taking the engineering of two different regions as an example, the paper analyzes the easily-soluble salt test and water quality analysis test of indoor reference to “Geotechnical Investigation Standards” Corrosiveness level changes. The results show that the content of groundwater changes after the treatment of mixed soil, and the impact of fly ash and ash mixed soil on groundwater is also slightly different. Under different groundwater conditions, the content of fly ash and ash The admixture of slag on the original area of groundwater corrosion results determine the impact is different.
