近年来，碾压混凝土重力坝沿坝体碾压混凝土层面的抗滑稳定性受到普遍关注．从结构方面考虑，提高碾压混凝土层面的抗滑稳定性可采用使层面向上游倾斜与折斜或局部提高下游坝面附近碾压混凝土层面的抗剪能力等措施．通过对龙滩碾压混凝土重力坝层面抗滑稳定性的分析可以看出：碾压混凝土层面向上游倾斜、折斜，或局部提高下游坝面附近的抗剪强度等措施，可在不增加或很少增加工程量的情况下，大幅度提高其抗滑稳定性，给工程带来较明显的经济效益．
In recent years, the roller skate stability of the RCC gravity dam along the RCC layer has received widespread attention. Considering from the aspect of structure, measures to increase the anti-sliding stability of RCC can be adopted by inclining and straightening the layer upstream or partially improving the shear resistance of the RCC layer near the downstream dam surface. Through the analysis of the anti-skid stability of the Longtan RCC gravity dam, it can be seen that the measures of the RCC layer inclining or inclining upstream or partially increasing the shear strength near the downstream dam surface can be achieved without increasing or Few cases of increasing the amount of projects, a substantial increase in its anti-skid stability, to bring more obvious economic benefits.
