摘　　要：石油化工项目多处软土滩涂场地,地基土压缩性高、沉降大,差异沉降易引起地下管线泄漏,危害严重。文章对软土地基的沉降原理进行分析,指出防治地下管线沉降的必要性,并对传统防沉降措施进行总结,分析其优缺点。提出优化的软土地基防沉降措施“关键点支承”法,对其可行性进行分析,并结合实际工程进行验证。There are many soft soil beach sites in petrochemical projects,with high compressibility and large settlement of foundation soil.Differential settlement is easy to cause leakage of underground pipelines,which is seriously harmful.This paper analyzes the settlement principle of soft soil foundation,points out the necessity of preventing and controlling the settlement of underground pipelines,summarizes the traditional anti-settlement measures,and analyzes their advantages and disadvantages.An optimized anti-settlement measure for soft soil foundation keypoint support method'is proposed,and its feasibility is analyzed and verified in combination with actual projects.
