摘　　要：城市地下空间开发造成的大规模弃土的放置、处置问题以及对地质环境的不良效应一直倍受关注,如何开展弃土堆填场地的二次开发利用工作对提升城市形象、建设宜居城市有重要意义。以武汉豹子溪流域大规模弃土堆填现象为例,全面调查评价堆填场地的基本状况,分析大规模堆填的地质环境效应。阐述大规模堆填改变原生地形地貌,改变地表水及地下水补径排条件,恶化水土环境,形成堆填体不稳定边坡;分析其侵占土地资源,造成水土流失,处理不当甚至容易引发崩塌、滑坡、泥石流等安全问题;同时在此基础上提出后期开发利用需要采取的相关措施建议,为更好的破解城市“渣土围城”困境提供参考。The placement and disposal of massive waste soils and minimization of the adverse effects on the environmental and geological effect induced by the underground space development in the urban area have received more and more attentions recently. This paper presents the large-scale waste soil fills in the Baozi Creek Basin of Wuhan case history. The subsurface conditions were comprehensively investigated and evaluated, and the geological and environmental effects of large-scale waste soil fills were analyzed. This paper also states that the large-scale soil fill changes the original topography, changes the conditions of groundwater and groundwater recharge, imposes an adverse effect on the groundwater and soil environment, and develops an unstable slope in fills. On the other hand, the soil fill will encroach on land resources, induce soil erosion. The improper handling of waste soil may even lead to safety hazards such as collapse, landslides, and mudslides. Suggestions of better utilization of the waste soils and minimizing the wide spread of waste soils are also proposed the paper.
