| 摘 要： | 库坡浸润线计算的准确性直接影响到坡体的稳定分析和工程治理.将库坡浸润线的求解简化为一维非稳定渗流问题,可以得到库水位等速下降时的浸润线解析解.通过对解析解曲线的拟合,得到了便于工程应用的简化计算公式.借助有限元模拟方法,对简化计算公式进行修正,并通过室内模型试验对修正公式进行了验证.结果表明,试验值与公式计算值较为吻合...

| Abstract: | The calculating accuracy of phreatic line in reservoir slope is important to the stability analysis and engineering treatment for reservoir slope.Regarding the problem of calculating phreatic line as one dimensional non-steady seepage analysis,the analytic solution of phreatic line in reservoir slope under drawdown conditions can be obtained.The simplified formula convenient to use in engineering is obtained by fitting the curve of analytic solution.Then,the simplified formula is amended by finite element s... |
