摘　　要：根据小湾工程坝前堆积体高边坡加固处理,提出采用大直径混凝土锚固硐的加固方案,作者用三维弹塑性非线性有限元,对加固后的堆积体稳定性进行研究分析,并对锚固硐自身的应力状态、锚固硐直径、锚固硐长短等不同因素对堆积体稳定性的影响进行了比较分析。This paper has put forward an alternative of reinforcing the accumulation body high slope located upstream of the Xiaowan dam by constructing large diameter concrete anchorage piers, and made a study and an analysis of the stability of the then reinforced accumulation body using the three-dimensional elastic-plastic non-linear finite element method. The paper has also made a comparison and an analysis of the influences caused by such various factors as stress state of the anchorage pier itself, diameter and length of the anchorage pier on the stability of the accumulation body.
