摘　　要：某水库库底地基变形较大,蓄水初期曾引起库底沥青混凝土防渗护面开裂。为研究进一步蓄水后可能产生的更大沉降及对沥青混凝土防渗护面的影响,对库底地基土层进行了反分析,研究地基土层的有关参数,利用反分析得到的参数进行了有限元正分析,研究地基的固结特性,为预测进一步蓄水后地基的沉降提供了重要依据。Large deformation was induced in soils of a certain reservoir bottom during the first water impounding, and resulted in cracks in the asphalt concrete impervious face. In order to study the possibility of further settlement and the influence on asphalt concrete face under further water impounding, back analysis of ground soil layers of the reservoir bottom is carried out; and then finite element analysis of the foundation is performed to predict further deformation of foundation and assess the possibility o...
