平原水库提高蓄水深度的研究

Study on feasibility of increase of water-storage depth for plain reservoirs

从坝体坝基应力、变形、稳定和渗流控制方面研究了提高平原水库蓄水深度的可能性 .研究证实 ,在黄河河口冲积和海相沉积的软弱地基上对坝基不作全面处理 ,而使蓄水深度大幅度提高是完全可行的 .研究成果可供平原水库规划设计参考 .

Based on the analysis of stress, deformation, and stability of and control of seepage from dam bodies and dam foundations, the feasibility of increase of water-storage depth of plain reservoirs is studied. The research shows that, without comprehensive treatment of dam foundations, it is feasible to greatly increase the depth of water-storage on soft soil foundations formed by alluviation at the Yellow River Estuary and marine deposition. The result is of a certain reference value to design and planning of plain reservoirs.
