摘要
为改善重力坝的抗滑稳定性 ,提出一种齿型基岩面设计与施工方法 .分析认为 ,若选择三角齿方案 ,在起伏角为 40°左右且齿高不低于混凝土最大骨料粒径时 ,基岩面的抗剪能力可望达到混凝土本体的水平 。
To improve the sliding stability of gravity dams,this paper proposes a kind of construction method by making a dentate joint between the dam and the base.Through the analysis,we know that if the tilt angle is made about 40° and the highness of triangular dentate is not smaller than the maximal diameter of concrete aggregate,the shearing strength of the joint between the dam and the rock will approach the strength of concrete.So,the sliding stability safety factor of gravity dams can have a great increase.
