| 摘 要： | 对重力坝设计规范中坝基深层抗滑稳定计算模型提出改进意见,建议坝基主滑动体与抗力体间界面--第三破裂面倾角选用非直立的坝基深层失稳模式,并导出了新的计算公式,编制了相应的电算程序,计算分析坝基深层抗滑稳定安全度.第三破裂面倾角根据坝基深层抗滑稳定最不利的情况确定.

| Abstract: | This paper presents the calculation model of simply non-vertical third angle of rupture for stable dam foundations and new calculation formula on the basis of traditional rigid limit balance method. Moreover, the program is established to the purpose of calculating and analyzing the degree of security of the anti-sliding stability of the gravity dam foundations. Regarding with the most destabilization of the gravity dam foundations with weak intercalary strata, it is possible to determine the third angle of rupture for stable dam foundations. |
