| Popis: | 102 Long time is required for clay layers under load compared with other soils. Deep mixing pile is a comparatively economic and fast method of ground improvement in order to speed the consolidation rate of clay. However, there seems some shortage of deep mixing pile with complicated geology in the theoretical and designed aspects. Recently, the numerical analytical method is used as the references of design with the availability of computer applied program. This study is aimed at the settlement, relevant mechanical behavior and the effect of influencing factors of soft clay without and with deep mixing pile as engineering projects using Plaxis 2D program. From the analyzed results, it indicates that (1). Deep mixing pile has the effect of speeding consolidation rate and reducing the differential settlement. (2).The final settlement is reduced and consolidation rate is speeded with the increase in the area of ground improvement. (3).The final settlement of pile can be effectively reduced, consolidation rate is speeded and differential settlement is decrease with higher modulus of pile. (4).The consolidation rate can be speeded with the increase of pile drainage. But there is no effect in the final settlement. |
