摘　　要：本文根据不同地质条件,不同软弱地基厚度,利用太沙基一维固结理论、有限元模拟条件计算并结合规范要求,分别分析换填、水泥搅拌桩、预应力管桩对淤泥质粉质粘土的地基处理效果,最后通过方案比选,从经济技术合理性的角度出发,确定具体采用的处理方法。According to different geological conditions and different soft foundation thicknesses,this paper uses Terzaghi's one-dimensional consolidation theory,finite element simulation condition calculation and combined with code requirements to analyze the effects of replacement,cement mixing piles,and prestressed pipe piles on the foundation treatment of silty silty clay,and finally through the comparison and selection of plans,from the perspective of economic and technical rationality,determines the specific treatment method used.
