  7. Based on the analysis, we gave an example to study the dynamic contact with friction of the intermittent joint, and got some essential rules : the friction coefficient could n ' t influence the distributing of dynamic stress on the contact surface, and the roading rates affected evidently on the dynamic characteristic on the contact surface. in the last part, this paper made respectively use of the time - history method and the response spectrum method to analyze the dynamic response of the rock slope on baise hydraulic power plant, and got the coincident resultant. simultaneously, the contact theory was applied to study the stability of the intermittent joints

    基於上述的接觸理論和接觸分析結果，本文在最後一部分中分別利用動力時程法和反應譜法對百色水電站尾水渠的巖質邊坡進行動力響應分析，兩者計算方法得出比較一致的結果，同時採用動力摩擦接觸理論重點分析了斷層對于邊坡的穩定影響，認為斷層的存在會使得巖坡的穩定性降低，在地震等動力荷載的作用下對于斷層將發生張開、閉合和錯動現象，尤其是動力荷載和其他荷載如滲流力等的耦合作用將會對斷層產生極為不利的後果，進而影響巖坡的整體動力穩定，應該要引起足夠的重視。
