摘　　要：经过大量试验表明淤泥软土地基其结构受外力影响变化较大,在经过一段时间沉降后其结构可慢慢复原,由于淤泥软土地基产生的沉降为不均匀沉降,会导致建筑主体产生倾斜、结构破坏,所以淤泥软土地基不适合作天然地基。将淤泥软土地基作为工程主体的基础时必须进行处置,常见的有强夯挤压、加压密实、砂井排水、淤泥固结等施工处置措施。在实际工程施工中如何处理好现有地基减少换填量,在保证工程质量的情况下,降本增效是一个值得我们技术人员思考的问题。After a large number of experiments,it has been shown that the structure of silt soft soil foundation is greatly affected by external forces.After a period of settlement,its structure can slowly recover.Due to the uneven settlement caused by silt soft soil foundation,it can cause tilting and structural damage to the main body of the building.Therefore,silt soft soil foundation is not suitable as a natural foundation.When using the silt soft soil foundation as the foundation of the main body of the project,it must be disposed of.Common construction disposal measures include strong compaction and compression,pressure compaction,sand well drainage,and silt consolidation.How to effectively handle the existing foundation and reduce the amount of replacement in actual engineering construction,while ensuring the quality of the project,and reducing costs and increasing efficiency,is a question worthy of our technical personnel’s consideration.
