摘要
结合凤滩大坝左岸岸坡渗流实测资料,通过定性和定量分析,综合评价了左岸岸坡的渗流特性;绘制了实测数据过程线,建立了回归模型,得出了水压、降雨、温度以及时效各分量的影响系数;并对各测点的异常进行了物理成因解析,对显著特征年用模型分离了年变幅.结果表明:大坝左岸岸坡的渗流性态基本正常.
Based on the data in field measuring the seepage of Fengtan dam, the seepage characteristic of the dam is synthetically evaluated by the qualitative and quantitative analysis,the graph of field data is drawn and the regression model is established, effect coefficients on water pressure, precipitation, temperature and component of effectiveness are obtained. The physical cause of abnormity fi＇om different measuring paris of the dam is analyzed, and the annual changing range in the obvious characteristic yeats is analyzed with models. The results indicate that the condition of the dam seepage is normal.
