| 摘 要： | 通过计算有地下水时多种工况下考虑及不考虑渗流时水泥土挡土墙的抗倾覆和抗水平滑动稳定抗力分项系数,认为地下水的渗流对水泥土挡土墙稳定性有很大影响。计算结果表明增大基坑内外水头差、墙底进入相对弱透水层、适当减弱坑底土的透水性等方法有助于提高水泥土挡土墙的抗倾覆和抗水平滑动稳定性。 |

Stability analysis of cement-soil retaining wall considering the seepage |
|
| Abstract: | It is indicated that the seepage of groundwater have a full impact on the stability of the cement soil retaining wall, by computating the subitem coefficients of resistance to its overturn and horizontal gliding. The computation results show that some methods, e.g., the increase of water head between inside and outside of the pit, the insertion into the relatively weak permeable layer by the pile tip and the proper weakening of permeability of the soil under the pit, are helpful to improve the stability of the wall to resist its overturn and horizontal gliding. |
