| 摘 要： | 本文建议以“沿坝底面抗剪最不利点未达到屈服状态”作为稳定准则,采用了真实弹性抗剪强度这一新概念,导出了岩基混凝土坝沿坝底进行抗滑稳定分析的理论公式,提出了确定安全系数的方法和计算公式。并证明当混凝土与基岩弹模比不同,坝高、坝型不同时,应采用不同的安全系数,坝越高、基岩越坚硬则安全系数越小。

| Abstract: | The stress state of the most unfavourable point for shear but still lower than the yield point on a dam base to be taken as the criterion of stability is suggested. A new concept—the real elastic shear strength, is adopted. The theoretical formulas for investigating the sliding stability along the base of a concrete dam on rock foundation are derived, and the method and calculating formulas for determining their safety factors are proposed. It is proved that variable safety factor should be adopted according to variable ratio of the modulus between the concrete and the foundation rock and different heights and types of dams. The higher the dam or the harder the foundation rock, the smaller the safety factor should be. |
