依据泥沙运动学及砂土蠕变的研究成果,对黄河高含沙水流运动规律及河床冲刷底面下砂基的变形进行了研究。采用高含沙河流的层移质运动解释了砂基蠕动,从流变学论述了冲刷高程以下砂基的蠕变问题,并研究了砂基的弹性变形。研究结果表明,黄河砂基“蠕动”不会对深埋的穿黄隧道结构造成影响。 Based on the research results of sediment kinematics and sand creep, the movement rule of high silt water flow in the Yellow River and the deformation of sand foundation under the riverbed erosion bottom were studied. The sand-based creep was explained by the layer-shifting motion of the high sandy river, the creep problem of the sand-based foundation below the erosion elevation was discussed from the rheology, and the elastic deformation of the sand-based was studied. The results show that the Yellow River sand foundation “creep ” will not affect the structure of the deep buried yellow tunnel.
