中文摘要：

黄河三角洲潮坪上构筑的道路使得道路两侧水动力条件出现差异。在道路两侧各选典型区域，取样进行X-ray衍射物相分析，概略分析潮坪沉积物的矿物成分及含量对水动力条件响应的变化，发现了强水动力环境使沉积物中碎屑矿物含量增大，黏土矿物含量减小，非均匀性增大的规律，此规律在表层沉积物中更为明显。

英文摘要：

The road paved across the tidal flat is perpendicular to the propagating direction of waves in the Yellow River Delta, which makes a sharp difference on the hydrodynamic condition of both sides of the road. We selected two representative research regions on both sides and took some sediment samples respectively. The X-ray diffraction phase analysis shows the characteristics of the mineral components and their contents which respond to the hydrodynamic conditions. In general, the content of detrital minerals increases in intense hydrodynamic condition. It is manifested more prominently in the superficial layer of the sediment.
