Geo-environmental impact due to several chemicals was studied to minimize the soil and groundwater contamination. The main results from this study can be summarized as follows : (1) Effect of acid rain on the physico-chemical and engineering properties of stabilized and unstabilized soils was evaluated. The equations to predict the neutralization of stabilized soil, which significantly affects the engineering properties, was proposed. (2) Environmental impact due to alkali from the stabilized soil was experimentally and analytically evaluated. The method to minimize the impact of alkali on groundwater was proposed. (3) Batch and column leaching tests were conducted on the specimens of stabilized MSW fly ash and sewage incinerated ash from the view of geo- environmental impact. Environmental impact of leaching heavy metals leaking from landfill sites was analyzed. (4) The performance of landfill bottom liners (geomembrane liner, clay liner, and composite liner) was reviewed and its evaluation method was proposed. "LANDFILL" concept, to create the new environment by reclaiming a huge amount of waste materials and excavated surplus soils, was proposed.

研究了几种化学品对地质环境的影响，以尽量减少土壤和地下水的污染。主要研究结果如下：（1）评价了酸雨对固化土和未固化土物理化学性质和工程性质的影响。提出了对固化土工程性质有重要影响的中和反应预测公式。(2)通过实验和分析评估了稳定土中碱对环境的影响。提出了减少碱对地下水影响的方法。(3)从地质环境影响的角度出发，对城市生活垃圾粉煤灰和污水焚烧灰的稳定化试样进行了批式和柱式浸出试验。分析了垃圾填埋场重金属淋溶泄漏对环境的影响。(4)综述了垃圾填埋场底部衬垫（土工膜衬垫、粘土衬垫和复合衬垫）的性能，并提出了其评价方法。提出了通过回收大量废弃物和挖掘剩余土壤来创造新环境的“LANDFILL”概念。
