摘要
经研究认为,有些文献介绍的岩基上挡土墙抗倾覆稳定安全系数计算新公式存在一定问题。建议仍用传统的公式计算,传统公式合理、意义明确、其结果唯一。对土基上挡土墙,当基底应力的最大值与最小值之比值满足规范要求时,挡土墙抗倾覆稳定安全系数满足规范要求,即挡土墙抗倾覆稳定,挡土墙抗倾覆稳定性无需验算。
The new formula for calculation of the safety factor of the stability against overturning of the retaining wall on rock foundation isdoubted. It suggests that the conventional formula shall be still utilized because it is rational, its meaning is definite and the result is sole.Regarding the retaining wall on the earth and when the ratio of the maximum value to the minimum value of the stress on the foundation bot-tom satisfies the requirement in the code, the safety factor of the stability against overturning of the retaining wall meets the requirement in thecode. Namely, the retaining wall against overturning is stable. Its stability against overturning is not necessary to verify.
