【摘要】 采用三维非线性有限元法,对园满贯RCC拱坝进行破坏模式及稳定性的研究,确定出坝基(肩)的点强度储备安全系数,以及在超载法和综合法下的破坏模式及稳定安全系数。结果表明:该拱坝安全系数满足工程要求,但温升温降荷载对坝体变位和坝身应力影响显著。更多还原

【Abstract】 The failure model and the stability of Yuanmanguan RCC arch dam is studied with three dimensions non-linear finite element method for the determination of reserve safety coefficient for dam foundation strength and the failure model and the stability safety coefficient with the overload method and the synthetic method. The result indicats that the safety coefficient of this dam satisfies the project demande, but, the temperature rise and the temperature drop load influences notably the deformation and the stress of dam body .更多还原
