摘要
软土在负压下进行排水固结产生的变形很大,属于大变形问题。分别利用大变形和小变形数值方法对负压下软土固结性状做了数值模拟,主要包括固结沉降和固结过程中的孔压变化,并与现场的实测数据进行对比,发现利用大变形方法得到的计算结果更加符合实际。
The large deformation for soft soil occurs when it is drained and consolidated under negative pressure. It does belong to large deformation problem. The numerical simulation on the consolidation properties of soft soil under negative pressure is carried out by the methods of large deformation and small deformation separately, mainly including consolidated setdement and the changing pore pressure during consolidation, moreover by comparison with field measured data, it has been found that the calculat ing results obtained by the large deformation method are even more in accord with practice.
