Abstract
There are two adjacent chemical pollution sites, belonging to the first andsecond land use plan, containing 16 contaminated areas. The pollutants are hexavalent chromium and benzo [a] pyrene. The contaminated soil is excavated simultaneously and group by group, remedied respectively in offsite plant. Based on the research, a set of sampling scheme is designed which is suitable for the foundation pit digging effect evaluation of multiple combined pollution foundation pitswith different land use plan and restoration target values. The results show that the evaluation of foundation pit digging effect of the two sites isup to standard, and the schemes of first excavation and expanding excavation are feasible. Scientific and accurate evaluation of foundation pit digging effect is conducive to reducing the risk of human health in the late management and utilization of the site.
