通过室内动水压力模拟试验,研究不同浸水饱和度、脱空面积、荷载位置、荷载大小和荷载速度等条件下的水泥混凝土路面板底脱空处的动水压力。结果表明:脱空位置在板角处引起的动水压力最大,为最不利脱空位置;随着脱空面积的增多,动水压力呈线性增大;当浸水饱和度低于60%时,动水压力增加的幅度较小,当浸水饱和度高于60%时,动水压力急剧增大;随着荷载速度的增大,动水压力显著增大,但荷载大小对动水压力影响不显著。
The hydrodynamic pressure at the bottom of cement concrete pavement under different conditions of saturated water saturation, void area, load position, load size and load speed was studied by indoor dynamic pressure simulation test. The results show that the hydrodynamic pressure is the highest at the corner of the plate due to the emptying position, which is the most unfavorable position. With the increase of the void area, the hydrodynamic pressure increases linearly. When the water saturation is less than 60% The hydrodynamic pressure increases sharply when the water saturation is higher than 60%. The hydrodynamic pressure increases significantly with the increase of the load velocity, but the load has no significant effect on the hydrodynamic pressure .
