上海某污染场地基坑工程设计与实践
摘要:上海某规划开发区域遗留的化工污染场地，需进行场地开挖辅助污染土壤的修复工作。针对场地污染物空间分布特点，周边环境情况以及污染物挥发性问题，通过基坑围护方案合理选型，对开挖区域进行分区分工况开挖设计，设计密闭大棚放坡开挖，以及局部采用重力式水泥土挡墙联合钢板桩等复合围护方案，使污染场地修复工作得到快速、高效、廉价、安全运行，且满足环境保护要求，为类似工程积累丰富的经验。
Abstract:The restoration of contaminated soil assisted the site excavation is netded by a chernieou contaminated site in a planned development area in shanghai.According to the spatial distribution characteristics of pollution sites,the surrounding environment and the volatility of pollutants,Through the rational selection of foundation pit protection scheme,excavation design of the area is divided into different working conditions,the excavation made is designed of closed greenhouse grading excavation,and the partial use of gravity type cement soil retaining wall combined steel sheet pile and other composite enclosing plan.The remediations of contaminated sites have been quick,efficient,cheap,safe and satisfies environmental protection requirements.It has accumulated rich experience for similar projects.
