整体式碾压混凝土重力坝的抗滑稳定性分析

On Sliding Resisting Steadiness Analysis of Entirety Roller Compacted Concrete Dam

文章采用三维弹塑性力学有限元法对整体式碾压混凝土重力坝的应力和抗滑稳定性进行了计算分析，并与刚体极限平衡法的计算结果进行了比较。结果说明，整体式碾压混凝土重力坝的应力和稳定条件较好，狭谷中的中低坝采用整体式碾压混凝土重力坝，具有明显的经济效益，在采取了严格的温控措施后，可推广采用。

The stress and sliding resisting steadiness of entirety roller compacted concrete dam have been analysed by the finite element technique of three-dimension elastic-plastic mechanics and compared with the calculation results of rigid body limiting.balance method in this paper. The results show that the stress and steady conditions of entirety roller compacted concrete dam are better and this type of dam can be adopted in construction of medium and low dams in a valley and has obvious economic benefit and can be spreaded after adopting strict temperature controlling measures)
