| 摘 要： | 应用三向应力作用的双剪强度理论,在Rankine土压力理论的基础上,得出三向应力作用下无粘性土的主动、被动土压力计算公式;将此公式应用于无粘性土中浅埋锚定板的容许抗拔力计算,使计算出的容许抗拔力值比以只考虑大小主应力而不考虑中间主应力的Mohr-Coulomb强度理论为基础计算出的该值增大,表明实际土体具有更大的抗拔潜力.

| Abstract: | The formula of Rankine active and passive earth pressure in triaxial state of stress in sand is established based on twin shear strength theory,and it is used in a calculation of the allowable anti-pulling force of shallow-buried retaining wall with anchored bulkhead in sand. The allowable anti-pulling force is bigger than that is calculated by the traditional formula of Rankine active and passive earth pressure,which is deduced based on Mohr-Coulomb strength theory in which the intermediate principal stress is not considered. |
