摘　　要：污染土的污染程度评价内容包括土壤物理力学性质的变化、对建筑材料的腐蚀性评价、对环境(人与植物)影响的评价。目前国内土木工程界仅关注前两类指标的评价,环境评估时仅关注第三类指标的评价。而对污染的建设场地而言,单一指标的评价方法欠全面。本文探索建设场地污染地基土的综合评价方法,以客观、全面评价污染土的污染程度,为后期修复与处置提供科学的依据。Approaches to determining the degree of contamination in a soil may include an evaluation of changes to the physical and mechanical properties of the soil,the extent of corrosion of building materials,and the impact on the environment（human and natural）.Currently,the first two aspects receive most attention in the domestic civil engineering field,while the environmental impacts are only considered when an environmental impact assessment is required.This limited approach is inadequate for contaminated building sites,and this paper considers a more comprehensive evaluation strategy that aims to determine,objectively and in some detail,the degree of soil contamination,and also to provide a scientific basis for later stage restoration.
