| 摘 要： | 该文对不透水地基上的均质土坝模型,在线性变化水位边界条件下的渗流流态和特性进行了实验研究。测定了非恒定渗流过程中坝体内浸润面的变化过程和压力水头的变化,通过对实验数据的分析,得出了非恒定渗流在水位变化过程中的物理力学特性。该实验对江河堤坝在洪水涨落期间的坝体内渗流场变化的研究有较高的借鉴价值,同时为渗流数学模型的可靠性和准确性提供了最直接的检验数据。

| Abstract: | The flow pattern and characteristics of the seepage are studied in this paper,which happens in a homogeneous earth dam model on the impervious foundation.And the water level boundary condition of the model is linear change.The change process of seepage free surface and pressure head in the earth dam are measured in the unsteady seepage process.By analyzing the experimental data,the physical and mechanical characteristics of unsteady seepage flow are summarized,which show in the water level change process.This experiment has higher reference value for the research on the seepage field change in earth dam during the period of the flood fluctuation on the river embankment.At the same time,it provides the most direct inspection data for the reliability and accuracy of mathematical model of seepage flow. |
