复杂相邻地块土壤修复基坑清理效果评估优化布点

Study on optimization of sampling design scheme for effect monitoring of complex adjacent foundation pits digging in soil remediation

通过分析基坑清理效果评估过程中的问题和难点,在参考相关技术导则和技术规范的基础上,设计了一套基坑清理效果评估的布点监测优化方案,结合案例提出了相邻但用地类型不同地块、基坑相互重叠或交叉、多污染物复合污染等情况下的布点监测思路,拟为类似情况下基坑清理效果评估提供参考。

By analyzing the problems and difficulties in evaluating the foundation pit digging effect and referring to relevant technical guidelines and technical specifications,a set of optimization schemes for sampling design and monitoring for the evaluation of the foundation pit digging effect is designed.Combined with this case,a scheme for sampling design and monitoring was proposed in the context of adjacent sites with different types of land use,overlapping or crossing foundation pits,and pollution from multiple sources.A reference is provided for similar projects to evaluate the effects of foundation pit digging.
