利用所编写的非稳定渗流计算程序，计算土石坝上游水位变化时自由面位置随时间的变化规律、孔隙水压力的分布情况。
The program is utilized to calculate soil rocks dam free surface position variation and pore-water pressure distribution condition with time when the up water level position changed.
有效应力分析方法中依据渗流场的计算分析得到条间孔隙水压力。
Based on computation and analysis of seepage field, pore water pressure of inter-slice is defined in the effective stress method.
因此，对坝体应力分布的研究要同时考虑孔隙水压力和渗流驱动力的作用。
Therefore, when we study the distribution of the stress in the dam body, we will consider both the action of pore water pressure and the action of flow drive force.
计算结束后得到的渗流场孔隙水压力为零的各点的连线即为浸润线。
The link line of the points whose pore water pressure equals zero in the field that is got after the calculation is the seepage line.
