| 摘 要： | 通过三维有限元计算，结合现场实测结果，研究基坑坑内土体加固控制变形的规律性。认为坑内加固提高了土体强度，减少了基坑坑底隆起量和基坑侧向位移，使基坑土体塑性区范围明显缩小，对控制变形是有效和显著的。

| Abstract: | According to FEM results and survey records,this paper analysed the sof-clay soil foundation deep pit deformation when the soil below the pit bottom was consolidated.It is concluded that,after consolidation,the soil strength gets higher,the horizontal and vertical displacements are reduced,and the plastic zone gets smaller.So the consolidation method is effective in deformation control. |
