中文摘要: |
本文提出重新研究抗滑稳定计算中的第三原则,用1949年以来各单位所做大型野外试验数据说明,使用这些原则计算实质上更合理。强调坝基不连续面用抗剪硐塞(键)处理时,尤其应该使用该原则进行刚体极限平衡意义上的抗滑稳定分析。通过实际工程应用和数值分析,建议有关单位研究将规范[2]中的剪摩抗滑稳定数值作适当降低。 |
英文摘要: |
This article brings up the necessity of further study on the third principle of sliding stability analysis and the reasonability of adopting this principle is demonstrated on the basis of test data in situ. It has been emphasized that this principle is especially suitable to the rigid body limit equilibrium calculation in sliding stability analysis of discontinuous plane strengthened by concrete block in dam foundation. It is suggested that the allowable shear-friction factors of safety in design standard should be reduced. |
