摘　　要：运用岩石弹性动力学理论及弹性力学变分法原理，提出、分析并论证了剧冲式高速岩质滑坡碰撞解体及冲击 成坝阶段滑坡坝冲击夯实动力学机理，推导出滑坡坝土石体压实密度计算的理论方程及公式，并以滑坡坝土石体土 工试验资料为依据，充分验证了符合实际情况的滑坡动力学新机理。Using the principle of elastic dynamics of rock and the variational method of elastic mechanics, the dynamic mechanism is explored of landslide damming by shock wave when the landslide mass is sharply disintegrated and collides with high moving speed. The calculating formula is proposed to deal with the compaction density of rock and soil. Based on the in-situ geotechnical testing, the proposed landslide dynamics is confirmed.
