Abstract:: The structural heterogeneity of current loess is the result of continuous infiltration of seepage water during the eras of geological history. We took homogeneous loess as the case, void ratio structure parameter m_p as indicators and seepage canal as devices to study percolation in loess. Study on movement characteristic of seepage water in unsaturated homogeneous loess and the relationship between vertical seepage and structural parameters m_p under single and multiple point water supply was carried out. According to the results, the longitudinal flow velocity is 1~4 times more than horizontal flow velocity; the lager the ratio of longitudinal and horizontal velocity is, the greater the influence on the structure of loess is; the longitudinal flow velocity makes a great contribution to current loess structure, however, the effect of the horizontal flow velocity cannot be ignored.
