软土地区大面积回填地基地基加固方案分析研究

Analysis and study of the foundation reinforcement for large area backfilled foundation in soft soil area

深厚软土场地经浅层地基处理后进行大面积回填,场地各区域于运营期间均发生不同程度的沉降,沉降对建(构)筑物的安全及项目运营产生了一定的影响。因此,需对场地现地面的沉降情况进行分析及评估,在确保安全的前提下,提出适宜该场地岩土工程条件且较为经济的地基加固方案,并为后续地基加固提供合理化建议,以期为类同项目提供借鉴意义。

The deep soft soil site is backfilled in a large area after shallow foundation treatment.Various areas of the site have different degrees of settlement during operation,which has certain impact on the safety of buildings(structures)and project operation.Therefore,it is necessary to analyze and evaluate the settlement of the existing ground of the site,put forward a more economic foundation reinforcement scheme suitable for the geotechnical engineering conditions of the site,and provide reasonable suggestions for subsequent foundation reinforcement,with a view to providing reference for similar projects.
