摘　　要：由于深厚软土在自身固结沉降过程中产生的负摩阻力及不均匀变形对桩基础、建筑物具有灾难性的破坏,故深厚软土区域进行桩基施工前应对软土进行有效处理。以某海外项目软基处理为例,采用指数曲线法、沉降曲线图解法(Asaoka法)和双曲线法预测最终沉降量,并进行了比较,希望能给工程技术人员提供参考。Because negative friction and uneven deformation of deep soft soil in process of self consolidation and settlement have disastrous damage to pile foundation and buildings,and the soft soil should be effectively treated before pile foundation construction in deep soft soil area.Taking soft foundation treatment of an overseas project as an example,this paper uses exponential curve method,settlement curve graphical method(Asaoka method)and hyperbolic method to predict final settlement,and makes a comparison,hoping to provide reference for engineering and technical personnel.

关 键 词：沉降预测 排水固结 最终沉降量
