摘　　要：在分布有深厚软土层的河、海岸边进行施工,软土地基的稳定性除受其本身压缩固结引起的地面不均匀沉降的影响外,其深部地基的稳定性也需引起重视。文中结合工程实例分析软土层下为倾斜坚硬层且倾向河道中间的情况,此时上方的填方或基础施工等很易引起软土层整体沿软硬层接触面向河中间滑移而导致地基失稳,并指出勘察设计中容易忽视的重点问题。In the distribution of deep soft soil of the river,coast construction,uneven ground settlement caused by the soft ground of stability in addition to and subject to its own compression consolidation,the stability of the deep foundation also need to pay attention to.In this paper,the project of the soft soil under tilt the hard layer and the middle of the tendency of river,at the top of the fill or foundation construction is very easy to cause the soft soil as a whole slip along the hard and soft layer of contact for the middle of the river and cause foundation instability.And it pointes out that is easy to overlook the key issues in the engineering survey and design.
